friend and fishing buddy roger a good blin would join them on the water. >> roger owned flagler title, one have to largest title insurance company in the country. roger liked the good life and shared with it everyone in his circle of family and friends. jimmy jimmy's brother patrick. >> he had the best of the best. he enjoyed the best of what life had to offer. jimmy trindade met roger in the boom time '80s of the real estate mark and if two became like brothers. vacations, parties, it was always the trindades and the gamblins. roger had two sons. his son chris was especially close to jimmy. both loved boats and jimmy taught him everything he knew about fishing and the sea. when they took separate boats from florida to the bahamas, jimmy made sure chris made the four-hour crossing safely. >> he was like a father figure to him. he also taught him everything he know, too.

>> twice a year, roger rented the isle resort of spanish key. and invited jimmy and his family for an all expense paid vacation that roger threw for friends and clients. don davis owns the island and spanish key resort. >> he did a lot of entertaining with his clients. he would bring 60 or so different folks. >> give me a sense for the kind of money they drop here. >> it has been sometimes $300,000, $400,000 a year. >> good customer. >> yeah. >> with money no object, they had fwhees him ian parties down to a science. bringing food to the boat. the sun sets do the rest. in december 2006, jimmy taylor and her mom candice were back at spanish key for aw two-week vacation. they would all spend new years together. and especially important day for taylor. >> my birthday is on new years. we had like band come. we were all just like partying. it was a lot of fun.

we just go out fishing every day. >> roger provided everything for his guests on those spanish key holidays. the best food and drink, champagne and steak. $is guests didn't spend a dime. he brought over three of his own power boats including this 38-foot donzi. one of the fastest boats on the high seas. he bought it just before christmas for $200,000. before roger bought the boat, it had been used in a movie version of a classic florida tv show. >> the 38-foot donzi that jim was pilot had been used on the filming of the miami vice. >> this is the donzi used during one of the night scene in the 2006 miami vice movie, starring jamie foxx and colin ferrell. when the vacation was oevg jimmy's family flew home. he skippered roger's new boat on the 100-mile trip back to florida. this is home video of jimmy

>> candice called me and said that jim was missing. and that the boys, meaning brian and chris, had lost sight of him. >> missing. lost sight of him. it must be a mistake, jimmy's family thought. when word reached jimmy' best friend, roger, he didn't believe jimmy could just vanish. his fate unknown. he vowed at that moment, he would do everything he could to find him. coming up -- while an ocean search was about to begin, jimmy's friends were convinced he would be back with a great story to tell. >> they're saying he probably ran out of gas. that he is drinking, waiting for someone to find him. >> and later, casey anthony's mom back on the stand today. >> how much had caylee grown since this video was taken? >> she had grown quite a bit. hoching toeico really se you % or more on car insurance?host: doartphos to do dumbhings? man 1: send, that is the weekend. app grapgic: yeah

somewhere out there in the mile of ocean between florida and the bahamas, where the currents swirl north, jimmy trindade and his 38-foot miami vice power boat were lost. >> i didn't believe it. i didn't think much of it at all. >> some of jimmy's friends like fred who had made the trip with jimmy many time himself, weren't too concerned. >> jim's level of competence around boats, he was not prone to mishaps. had something happened to the boat, when they found the boat, they would find jim. >> you figured you would have a story to share with him over beers when he finally made it to shore. >> a joke or two anyway. it was chris gamblin who had radioed the coast guard to say

jimmy was missing. the coast guard put out an alert and geared up for a search and rescue operation. paul, alber of the florida marine patrol heard the alert. he met chris gamblin and his friend brian when they pulled into a palm beach marina. they were about three hours overdue. >> what did they say had happen? >> at some point during the trip, the smallest boat had a mechanical issue. they had to slow down and take care of it. >> brian was in the smallest boat and jimmy was in the biggest and fastest a few miles ahead. >> they had radioed to him saying we have a problem. we need to stop. he indicated to them that he would wait for them but when they tried to reestablish contact, after they cleared up their breakdown, they were unable to could not tack him. >> so they will you that they never talked to him again or saw him again. >> that's correct. >> they said they were in a hurry to get to jimmy's house where his family kept vigil. after a taking a quick look at

the boats, alber let the young men go. >> we suggested they come to candice's house. we need to talk to them. >> chris and brian tried to reassure jimmy's daughter taylor, saying jimmy, the experienced boater, was probably taking it easy waiting for help. actually joking about it saying he probably ran out of gas. drinking his rum on the boat. waiting for someone to find him. >> but chris's father roger was taking his best friend's disappearance very seriously. roger, a man used to getting thing done no matter what the cost, immediately lined up private search planes and boats to look for jimmy. but there was a problem. president george bush and air force one were in palm beach county that day. >> at that particular time there was a no-fly zone called. with hours lost waiting, roger immediately got a plane in the air but returned shortly after as darkness turned blue seas to black.

the coast guard also launch ad falcon jet with infrared night vision cameras. around midnight it spotted something about 40 miles off the coast of florida. >> got him. he's at 10:00. >> got it. okay. >> we get a call from the coast guard that they had identified the boat and they were sending a marine boat, or a cruiser, to intercept it. >> and you're thinking at that point, that's good news. >> i'm thinking, great. >> news. if they foun" the boat, my thought is they found my brother. >> do you see any people? >> then another call. more good news. >> we got a call later in the mo)ning that the infrared showed that perhaps someone was on the deck. but not moving around. so we're thinking, maybe he's sleeping on the deck. >> programs it would turn out to be just another sailor story to laugh about over beer. then at 5:00 a.m., the phone rang again.

>> it was a woman, coast guard on the phone who said we've boarded the boat. and i need to report to you, there is no one on board. >> your heart had to sink. >> what do you mean there's no one on board? how could that be? >> and then the second thought was, he's gone. how can i live life without my brother? >> what did your mom say to you? >> she said, they found dad's boat but he wasn't on it. and i didn't know what to think. i just started crying. >> but jimmy' best friend roger was not about to give up hope. his private search would turn into an obsession. him to choose between his best friend and his family. that search would begin with jimmy's boat. what searcher found and did not find was disturbing. >> it looked like, if i had

wiped everything down, made it nice and clean and sat it in the middle of the ocean.

within a week of jimmy trindade's disappearance, the coast guard had called off its search. but his best friend roger gamblin kept looking. for jimmy daughter's taylor, roger was her best chance. >> we had plane going out every day searching for him. i know it was really scary because they had the seas were extremely rough. if he was in the water, there was no hope for him. w the coast guard stepping out.

picture, the fbi became more active, investigating the possible death of jimmy trindade at sea. but roger gamblin wanted to mount his own investigation independent of the fbi. he had set up his war room and now had a website staffed by what he called the jimmy t recovery team. he also hired three retired fbi agents to help as private investigators. when the coast guard returned roger's 38-foot donzi, he parked it in his driveway and had his 3 employees take everything off checking to see what might be missing. obsessed with detail, roger made sure everything was videotaped. one of the retired fbi agents, joe del campo, then did forensics on the boat looking for blood, hair, fiber or prints. anything that might shed light on what happened. >> if they tried to overpower jimmy -- >> it could be somebody's blood

on board. the one problem was we received the boat a week later after the incident had taken place. where tons of people had walk on the boat. >> to see the very least, this was a compromised environment, if not contaminated. >> i would say beyond compromised. there was nothing there of evidentiary evidence we could find. >> with no arrests, the fbi seemed to be languishing. jimmy's family had him declareñ legally dead. that seemed to be tend of the story. áhen ten months after jimmy's disappearance, a possible break. a homeland security agent named don guthrie got a call from an informant of his. a former drug smuggler. guthrie spent 30 years on the ocean chasing drug smugglers. he asked that we disguise him. >> the smuggler asked me if i was sitting down. i said why? i'm in the bahamas and the word i'm in the bahamas and the word is that jimmy trindade's donzi,

his 38-foot donzi was sabotaged by somebody pouring water in the gas tank. that this endeavour was related to a cocaine smuggling venture. >> this was the first time an informant had come forward with specific information that drug smugglers were involved in jimmy's disappearance. investigators had found a small baggy of cocaine and some residue on the boat. but guthrie ruled out that the drugs belonged to jimmy. if they weren't jimmy's, who did they belong to and why was the boat sabotaged? looking for clues, guthrie went back and questioned the coast guard men who boarded the boat. coast guardsmen nathan black well told guthrie, when he check the boat's gps to find out where jimmy had traveled that night, the gps for the most part, had been erased. >> i couldn't determine where exactly the boat left from and get its course and where it was headed. it was strange. something definitely didn't add up. >> there was something else

about the boat that didn't add up to the coast guard. >> when we got therqit was sitting dead in the water. i turned the key to see if there was fuel in the boat. and the gauge, it said water and fuel. >> jay christo of the coast guard found the boat was emof fuel but had a lot of water in the tank. that much water would force the engines to run poorly and possibly burn out. as the coast guard infrared cameras showed, only two of the three engines displayed any heat from running. the third engine had already shut down, causing the boat to go around in circles. but where could the water have come from? rosie tone grand key marina where the boats gagsssed up. there was never water in the fuel. >> if the water didn't come from the marina's fuel supply, it appeared to agent guthrie that his informant's tip was correct. >> it was three to four inches have walter in that 320 gallon

fuel tank on the 38-foot donzi. it fathers vessel may have been sabotaged at grand key. >> guthrie concludedyú& as jimmy left grand key, a drug deal was about to go down at sea and the participants didn't want jilly to interrupt it. so they sabotaged his fwoet slow him down. but agent guthrie believes the sabotage didn't work as planned. >> jimmy may have pulled up on a scene where -- >> on a drug deal. >> on a drug deal that was during and basically, he argued with one of the smugglers and this individual blasted jimmy right on the 38 donzi. >> and this come from a reliable confidential informant. >> it come from a reliable person that has a lot to lose by admitting this endeavour. that's all i'll say now. >> there was one piece of the puzzle that guthrie hadiest to figure out. what was jimmy doing in the middle of a drug deal what made him stop in the first place? jimmy's brother patrick thought

the last two people to see jimmy alive, chris gamblin and brian pratts, might have some answers to those questions. >> when i was trying to question them as to what happened, it was very obvious and the gut feeling in me that we weren't getting the truth. >> growing suspicion aimed at jimmy's fellow voyagers. >> we were at odds because of the lack of truthful answers from the last two people to see my brother. say something inter so how about this weekend we learn some new tricks of the trade... then break out our doing clothes and get rolling. let's use some paint that helps us get the job done in record time and makes a statement when we're finished. we're lowering the cost of a new favorite color. more saving. more doing. that's the power of the home depot. get five dollars off gallon cans of our top paint brands now through july 4th only.

as homeland security agent don guthrie started investigating the disappearance of jimmy trindade, he got an earful from the missing man's brother patrick. jimmy's family had grown increasingly frustrated with jimmy's best friend, roger gamblin. while roger seem to be doing everything he could to find out what happened to jimmy, patrick felt he should be looking closer to home for answers. >> we were at odds at this point because of bizarre behavior and the lack of truthful answers from the &ast two people to see my brother. chris gamblin and brian pratts. >> patrick's suspicion started the night jimmy disappeared. the coast guard had just called with the news they found the boat but jimmy was not on it. >> brian and chris were laying on the couch. and i saw chris's head. and he looked up. when he saw me, he put his head back down like he was sleeping. >> faking it. >> yes.

but at this point i couldn't deal with chris. i needed to continue to make sense of what was happening at that moment. whatever happened to jimmy trindade on this boat, one thing is for certain. neither jimmy's family nor many of his friends nor federal investigators believed chris and brian were sharing everything they knew about what had happened. their story seemed to shift with every telling. the only one who seemed to believe them was chris's father roger. the man in charge of the massive search for his best friend jimmy. the rift between the gamblin and trindade families would turn into a barrage of accusations of betrayal. two families, once so close, were now split along blood lines. chris's attorney, richard lubin. >> it was very painful for roger that this man who had been so close to, like a brother, and now his family was suggesting that roger's family had something to do with his death. and he didn't like that.

>> roger became so defensive about the allegations from jimmy's family, he came up with his own theorys. one surprisingly was that jimmy was not dead at all. he floated the story to a local newspaper that jimmy may have engineered his own disappearance. >> is there any chance your father would have tried to engineer his own disappearance? >> no. he loved my mother so much and loved me so much. and he would never leave us for any reason. >> and then roger attacked jimmy's wife candice, telling a report per perhaps she was involved. >> roger was floating stories, saying something like, well, his wife was the only one who would benefit from his missing. >> roger had theory after theory after theory. and most of them very bizarre. and i believe the reason for that would be to continue to steer people away from what i believe to be true. that brian and chris know more than they've told us.

>> agent guthrie dismissed roger's latest theories and instead went back to carefully check out chris and brian's stories. >> is it fair to say that chris gamblin's story didn't hold up? >> that's fair to say. >> for example, the story of how chris and brian were separated from jimmy. all along, chris had said when one of the boats broke down, he radioed jimmy who said he would wait for them a few mile ahead. but jimmy's friends and family told guthrie that as the most experienced boater and with his best friend's son involved, jimmy would never leave them behind. >> did jimmy trindade strike you as the kind of skipper who would leave younger boaters behind with a mechanical problem? >> he was very loyal to roger. and he would not have allowed those boys to get out of his sight. >> remember, the two told investigators, that brian's boat, the smallest one, had mechanical problems.

the reason they gave was that an oil reservoir flipped over and stalled brian's boat. but guthrie said just before the trip to the bahamas, roger her that problem repaired. >> he had replaced the oil reservoir and put a new strap on that canster. the way it was situated between two batteries, it would make the flipping over very unlikely. >> guthrie's suspicions flew even more when their story changed about the last radio contact with jimmy. chris said he thought he heard jimmy calling for help. >> he stated that he heard over the radio jimmy calling u.s. coast guard, u.s. coast guard. and theyer in made contact with him again. >> is there any evidence to support chris gamblin's claim that he heard jimmy trindade call the coast guard on his vhf radio for help? >> no. we interviewed individuals in the area. we spoke to the florida marine patrol officer that was monitoring the radio traffic.

and -- >> he didn't hear anything. the coast guard never heard anything. >> the coast guard didn't hear anything from jimmy. >> what's more, if chris and brian heard jimmy calling the coast guard, why didn't they mentron it to the first law enforcement officer they met at the dock that night? paul alber. >> it was definitely a detail that they left out when they spoke with me. if i was traveling with a friend and i heard him calling for the coast guard, i would be pretty concerned about that. >> so the odds are -- >> probably didn't happen. right. >> guthrie also learned that early on in their investigation, fbi agents had asked chris and brian to take lie decker tests. the fbi would not share those test results with "dateline." but one of roger's private investigators, ross gaffney, can did. >> we were told there were signs of deception. while they may not have actually participated in his disappearance, that they knew something about his

disappearance. >> and one other thing guthrie look at. five months before jimmy was lost at sea, chris gamblin was arrested for cocaine and marijuana possession. in a plea agreement, chris serbed eight days in jail. but his record would show he was never formally convicted of a crime. agent guthrie now had his theory as to why jimmy's boat was sabotaged and who was involved in the drug smuggling. he believed jimmy had tried to stop the drug deal that day because his best friend's son, chris gamblin, and his friend brian pratts were somehow involved. their they posed the theory that somehow mr. trindade had come upon the boys involved in a drug deal and he was killed in their presence. it is a theory. but there is no evidence to party is. >> chris gamblin and brian pratts denied they were involved in any kind of drug deal at sea,

nor witnessed jimmy trindade's murder. >> brian was consistent. that he knew nothing about how jimmy had disappeared or had, that that he had not been involved in jimmy's disappearance and certainly hadn't seen jimmy murdered. >> chris's attorney said the young man would never do anything to put his father's best friend in jeopardy. if you're going to do a drug deal, why would you do it with him anywhere around? the whole thing is crazy. just crazy. >> attorney lubin said even after chris was being treated as a suspect, he still voluntarily submitted to a polygraph and dna testing. roger even hired his own polygraph examiner. and those test results obtained by "dateline" showed no deception. chris gamblin and brian pratts have not been charged with any crime. on the two-year anniversary of jimmy's disappearance, chris showed up for a jimmy t golf tournament. toasting jimmy with his favorite

drink, mount rum. >> cheers. >> cheers. >> palm beach post editor jan tuckwood. >> any time you get a guy lost at sea, people are turning against each other. lifelong friends. it is going to be a mystery that would last a long time. how strange it would get, he we did not know. >> strange would be the word all right. when roger just like jimmy vanished. >> are these disappearances related? >> a whole new round of questions begins. and later, an emotional day at the casey anthony trial. as her mom tak [ coach ] in albuquerque citi pre-approved my mortgage.

roger gamblin had spent more than two years and hundred of thousands of dollars to find out what happened to his best friend jimmy trindade. but federal investigators and his best friend's family thought roger's son chris knew more the whole story was doubly hurtful according to his attorney, richard lubin. >> it broke his heart that jim

was gone and it broke his heart that anybody would think his son had anything to do with it. >> and then in june 2008, two and a half years after jimmy trindade went missing, this strange story got even stranger. roger gamblin didn't show up for work one day. calls to his phone and knocks on his door went unanswered. it appeared roger, the wealthy businessman and fixture in the palm beach real estate world, had just disappeared, along with his wife. tuckwood. >> so now everybody is speculating. related? does roger know where jim is somewhere? it opens up a whole other pandora's box of speculation. who know? >> had roger met the same fate as jimmy? or had the two best friends plotted all along to meet later in some tropical paradise. did roger perhaps take with him the secret of jimmy's

disappearance? within days, the answers became pretty clear. roger's disappearance had nothing to do with jimmy's. the fbi was investigating funds missing from his title company. and before he could be arrested, roger took some of the money and ran. >> ups and disappears one day. takes the money from his business and he's gone. >> while the allegation was that roger had stolen $10 million @r(t&háhp &hc& from escrow accounts, it appears he spent a lot of it paying for the bahama partiqák the miami vice boats, and later his son's legal bills as well as the search for jimmy. when the real estate bubble burst, roger couldn't repay the accounts. roger and peggy gamblin written died for mail and wire fraud, as well as conspiracy. the fbi learned they were last seen on a private jet headed to texas where roger has family. from there, the trail went cold. after a while, relatives assumed roger, who suffered from heart problems, had died.

>> earlier today, a judge heard from some of the people the gamblins allegedly stole from. >> meanwhile, creditors and home own here lost escrow money to roger went to court to get it back. >> it did take a big hit on me and my family. >> for two and a half years, there was no sign of roger and peggy. that was about to change, far away from florida in the colorado rockies. in the mountains outside durango, colorado, a couple named ron and nancy jenner showed up and rented a cabin. they made home improvements, including 12 surveillance cameras and six motion detectors. according to the cabin's owner, they said they were afraid have bears. >> as soon as you entered the driveway, they knew you were coming. the locals down at the shank house bar and grill. she was quicklyñknown by the nickname of red.

ron was too sickly to work. but nancy picked up odd jobs. sth worked as a cleaning lady. >> she also worked at this convenience store. >> hard working. >> last december, ron jenner went to a durango hospital with heart problems. he had a defibrillator which is encoded with patient information. after a routine scan, doctors were puzzled why the device showed a different name and notron jenner. in w$at may be a first in how fugitives get caught, hospital lawyers googled the name that appeared on the medical device. wondering why a patient would lie aboqhis eye dent. the name on the device was roger gamblin. and gamblin was a fugitive. two days later the fbi arrested roger and his wife peggy as he was released from the hospital. >> you can't make this stuff up. >> you can't make it up. >> the gamblins were under indictment and charged with stealing millions, it is unclear how much of that they had.

roger look pretty scruffy with his gray beard. the month before they were landlord if they could pay the rent late. roger and peggy gamblin were sent back to florida and held without bond. now with roger in custody, patrick trindade saw an opportunity. he hoped roger knew more about his brother's disappearance, and might tell all to avoid possible prison time. >> and gave me a flicker of hope that perhaps we would find out more. rather than him facing the rest of his life in prison. he had spent all this time apparently in my eyes, protecting chris. i didn't think he would really stop now. >> breaking news tonight. a once high-powered businessman accused of fraud and conspiracy has died today while in federal custody. >> like patrick trindade's hopes, roger gamblin didn't live long. one month after his arrestering died in custody from heart failure. his wife peggy recently entered

a plea deal to a lesser charge of covering up roger's crimes and faces three years in jail when sentenced. the case of jimmy's disappearance, while still open, seems dead, too. recently the lead ago don guthrie retired from the department of homeland security. >> how much did it hurt your investigation that you didn't get started until ten months after jimmy trindade disappeared? >> it affected it in a huge way. >> do you think had you gotten on to this right away -- >> yes. >> we would have suspects in custody? >> i think so. >> for jimmy's daughter taylor, the pain continues in unexpected ways. although she stopped talking to chris long ago, recently she received two text mssages from him. what was the first text? >> stating that he loved my dad. that he promised his dad that he would find out what happened. >> so how did you react to that? >> i just blew it off.

>> and literally just days before this interview, chris texted you again. >> yeah. he asked me if i got the same phone calls he did. that he heard that jimmy will be to the u.s. soon. >> what do you think the purpose of that was? >> i don't know if it was a hurtful text or him just trying to cover up something. i don't know if it was just on his mind or what was going through his head. >> chris gamblin seem to believe jimmy is still alive. even though he signed an affidavit six months after jimmy's disappearance saying+ô o cf1 o believed jimmy died at sea. chris declined requests for an interview with "dateline." but in an interview wrote that he wanted, quote, to move on and start with my livism want to pray for healing and reconciliation for everyone. i pray they find jimmy as well. >> what has been the hardest part of this for you? >> i just feel my dad, i wish he was around. i graduated last year. ñphe was not there for my

graduation. it's just hard. >> taylor trindade, now 19, has spent a quarter of her life without her father. but she still finds solace in the thing that made him happy. the smell of the ocean, the salt spray, and the wind on her face. >> the ocean air reminds me of him. it is a peaceful place. me and my friends have boats so we'll go out fishing and stuff. it reminds me of him and it put me in a happy place. >> let's get the latest now in the casey anthony trial. her mom took the stand yesterday and dropped a bombshell. today she was back with another day of emotional testimony. here's dennis murphy. >> do you know what that photograph is of, mrs. anthony? >> yes. >> cindy anthony, the mother of the accused, was back on the stand today as a defense witness. wiping tears as she looked at snap shots taken of her granddaughter caylee in the backyard swimming pool. >> it's a picture of caylee walking up the ladder.

and i'm behind her, holding her. >> i would like to tell you what happened. happened. the defense said weeks ago in its opening statement that caylee wasn't murdered by her mother casev rather, the child had died in an accidental drowning in the aboveground pool in this photo. this pool ladder was removable so caylee couldn't get into the water by herself. >> we took extra precaution every day to keep the ladder off the pool. >> but cindy anthony testified her granddaughter had recently learned to climb the ladder by herself. and she told the court that on the day the defense claimed that caylee drowned, she remembered coming home from work to find the ladder in place against the pool. >> was that a highly unusual event for you? to see that? >> yes. >> the testimony was a rare flash of emotion in recent days. >> i don't understand how could you get those with mixed up. >> more than a week into the defense's case, it has been @r(t&háhp &hc& mostly tedious forensic testimony. >> he did not list carbon --

>> the lead detective has been badgering crime scene teches and badgering crime scene teches and scientific experts about their work on evidence collected from where little caylee anthony's remains were dump asked processed from the trunk of the car, driven by her mother casey anthony. >> the defense has done a good job of taking every little piece of the science and raising a doubt about it. >> beth karas, a correspondent and former prosecutor, is covering the trial for "in session" on thetrutv network. she said jurors may still be wondering about some holes in the prosecution's theory of the case. >> the open questions are, how was it done?% where wait done? why was it done? >> but the collective glaze in the courtroom after more than a week of droning scientific testimony, shattered quickly when cindy anthony, the accused' mother was first call back to the stand yesterday. what a story she had to tell.

>> i almost dropped my pen. >> in unexpected testimony, the mother said it was she who had searched on the home computer for information about chloroform. >> i started looking up chlorofrm -- i mean, clore fill. that prompted me to look up chloroform. >> why is that important? the prosecution says ominous computer searches on topics like chloroform and neck breaking were made in the home months before the child went missing. it is the foundation of the argument fors premeditation in the death penalty case. now the mom is saying, she made at least some of those computer searches while researching whether leaves in the backyard were making her dog sick. >> i thought to myself, why are you saying this now? she waits until close to the end of her daughter's capital murder trial to drop a bombshell. >> while cindy hanth mentioned her computer searching to prosecutors in a deposition two years ago, they seemed surprised

by her testimony for the defense. earlier in the trial, the prosecutors had taken a kid cf1 o gloves approach to the emotionally fragile mother. but not yesterday on cross-examination. >> did you input the words into the google search engine, how to make chloroform. >> i don't recall putting in how to make chloroform. but i did google search chloroform. >> and even though her employment record shows she was at work during the time the searches were made on the home pirate, cindy now tells the prosecution, she may have had a day off or left work early on those days. >> very convenient. not telling them that for three years? >> caseyies brother lee also return to the stand today. he lost his composure as he rektd being angry at the time of caylee's birth. how he felt about being excluded from the news of the pregnancy. >> i was angry with everyone in general that they didn't want to include me.

>> while it was unclear where the defense was headed with these questions, the testimony from lee made a big impression on casey. some sensational courtroom moments with likely more to come. >> every day we wonder, what is the next bombshell? because there are a lot of thing that are happening that are unpredictable. that's all for this edition of "dateline" friday. we'll be back again for "dateline" sunday at 7:00, 6:00 central. i'm lester holt. for all of us at nbc news, good night. -- captions by vitac
