[ bleep ] they can frame anybody right, that's how stupid those college geniuses are. my wife, she's bleeding all over the place. >> a family dog witnessed a brutal murder. >> whoever entered new the victim, knew the dog. >> an animal expert finally got the dog to talk, just not in the usual way. >> there are two sides to palm beach county, florida. it's home to some of the wealthiest people in the world, but a few miles away live people struggling just to pay their rent. >> we have a lot of crime for the size of community we are, we have an extensive amount of violent crime, a lot of murders.

>> cathy and jeffrey lamb didn't live in one of the palm beach mansions. jeff was a tow truck driver. cathy worked for the walgreen drugstore chain. >> i liked jeff. he was a good kid, good to cathy, and the main thing was she loved him. >> on june 15, 2004, jeff got home from work around 7:00 p.m. but when he walked inside, he found blood everywhere. >> what's the problem? >> my wife, wife, my wife's hurt and there's blood everywhere. >> he was hysterical on the phone. he was crying so much that i think the 911 dispatcher kept referring to him as a woman. >> okay, ma'am, i need you to take some deep breaths, breathe in and breathe out. okay. now, are you having an asthma

attack? >> no. my wife -- my wife is on the floor here. she's bleeding all over the place. >> the blood spatter was completely up one wall behind where her head was, and blood spatter was all over a desk and it flew underneath the desk to a wall through the chair. it was a lot of blood and it was very gruesome. >> when the ambulance crew arrived, they pronounced cathy lamb dead at the scene. she had been beaten to death. >> this wasn't an injury that was caused by one blow or two blows. there were multiple blows to the head. this was something heavy that made these -- that could create these injuries. >> between the first blow and what eventually killed her, she had to have been suffering, she was in pain. and she had to have been thinking, why? >> the murder weapon wasn't found at the scene.

although it looked like it was a blunt object with a hexagon shape at the end. two of couple's three dogs were badly beaten too. they were found unconscious nearby. >> they were both euthanized because of the head injury, severe head injuries. >> the dogs had blood on their paws and mouths, an indication they probably attacked the killer as he was striking cathy. >> the pack thing would have kicked in and the two of them would have packed up on this one individual. so you would have had, in my opinion, you would have had probably quite a bit of damage. >> and the killer would be bleeding profusely from those wounds. >> it was decided that we would go ahead and clip their nails and swab their mouths because, again, if this was a home invasion type situation, there's a good chance that these dogs had scratched or bit the intruder.

>> the couple's third dog was found in a closed bedroom, apparently unharmed. >> it was a mystery why anybody would choose to go into this residence with the three dogs, especially being large dogs. >> whenever i talked to the detective kim bradley, she told me we will get justice for cathy, we are going to find the person that did this. hey kevin...still eating chalk for heartburn? yeah... try new alka seltzer fruit chews. they work fast on heartburn and taste awesome. these are good. told ya! i'm feeling better already.

with no clear suspects, at least none we're being told about, the sheriff's department is turning to the neighborhood for help, passing out these flyers with cathy lamb's picture on them and asking people who may have any information to give them a call. >> cathy lamb's murder scene was stranger than any investigators had ever encountered. at first they thought the motive for robbery. cathy's husband, jeff, said the only thing missing was a pair of cathy's gold diamond earrings. >> in the master bedroom, all the drawers had been pulled out. the clothes weren't disturbed. there's lots of jewelry and

items on top of the dresser. >> the medical examiner estimated that cathy was murdered between 4:30 and 5:00 in the afternoon. since jeff lamb found his wife's body, he was naturally considered a suspect. >> jeff lamb had a very good alibi. there are several people that can vouch for his whereabouts at the time. >> soon, other suspects emerged. while police processed the crime scene, a woman named joy slidell arrived and introduced herself as jeff lamb's fiancee. >> it's curious that the husband, the grieving husband, is now being consoled outside the crime scene by his fiancee. >> i think human nature would tell you when a guy tells you he has a good relationship with his wife and girlfriend or fiancee shows up at the crime scene, it's going to start make you think something's going on here.

>> while jeff admitted he had an affair with joy, he claimed their relationship was over. >> jeffrey's story was he had reconciled with his wife and they were going to be permanently living together again. it was contradictory for joy to come over and say, no, we're moving over to this house in jupiter. >> joy slidell was now a suspect too. but she had an alibi for the time of the murder. she worked as a waitress at a nearby restaurant and dozens of customers saw her. next jeff's cell phone records identified yet another suspect. on the afternoon of the murder, jeff lamb spoke with another female friend on the telephone. >> the first phone call that was made after we believe the murder took place was made to lisa aserbell, who turned out to be joy slidell's neighbor.

>> lisa aserbell was a married mother of two children. when questioned by police, lisa admitted she, too, had a relationship with jeff lamb. in fact lisa's husband had caught them together in a compromising situation just a few weeks before cathy lamb's murder. >> so i kicked my front door in and he was on my couch with no shirt on. he had shorts on or pants on or something, no shirt or shoes. i got mad at him and chased him out the black sliding glass door. >> ray then said he called jeff on the phone. >> i left a message on his cell phone that if he came around my house or my family again, i was mad, i said i'll do anything to protect my family and i don't want him around. >> when we first learned that raymond had been so sangry with jeff, he was somebody we were interested in, we certainly had to investigate. >> both ray and lisa aserbell had an al alibi for the day of cathy's murder and were eliminated as suspects.

but police were still troubled by lisa's telephone calls to jeff on the afternoon of the murder. lisa said they were purely social. phone records proved that lisa made these calls from home. but jeff's cell phone records indicated jeff wasn't at work, as he claimed. >> we get the phone records, which show he is down by that house. the phone towers are hitting off of phone towers closer to the house than they are where he claims to be. >> and investigators found another contradiction. jeff said his dog bandit was in a locked bedroom when he found his wife's body. but investigators found bloody paw prints in the bedroom. and the blood was cathy's. this meant the killer put the dog in the bedroom after cathy's murder.

an unknown assailant not only attacked cathy lamb but also her two dogs, nipper and dakota, presumably with the same weapon. >> cathy's friends and even mr. lamb himself said that those dogs that were in that house would have torn apart a stranger.

>> but investigators couldn't understand why the dogs weren't all together. >> why were her two smaller dogs beat so severely and yet the biggest dog of the group was never struck? and the dog was also locked in a bedroom. >> the third dog was a hybrid, a wolf mix that was owned by the husband. >> investigators thought the blood on the dogs' mouths and paws had come from cathy's attacker. but forensic testing disproved that. >> the swabs and clippings that had been taken from the dogs came back negative for any human dna. >> the couple's third dog bandit was initially believed to be unharmed, but the humane society discovered he suffered injuries, too, but not from the killer. >> we discovered that bandit actually had several puncture marks, which indicated that he

had been in a fight and probably had been in a fight with the other two dogs. >> so the dogs attacked one another, but not the killer, even while the killer was beating them. >> and they stood there and they took their beatings, and then they went and they hid. >> to animal behavioralists, the reason was clear. >> and a stranger wouldn't have been able to beat those dogs brutally the way they were beaten without them fighting back. somebody obviously knew the dogs, so it had to be somebody that, you know, they weren't going to fight back. >> it seemed pretty clear from the evidence that only one person could have done this crime. >> but prosecutors had a problem. the surviving dog, bandit, obviously couldn't tell police what happened. so investigators had to dig deeper and started by looking into jeff lamb's finances. a few years earlier, jeff's former employer accused him of

stealing almost $30,000. he returned the money and agreed to pay an additional $20,000 fine. his current job as a tow truck driver didn't pay particularly well. and these payments were a hardship. >> $20,000 isn't a lot of money to most people, but to some people, it's like a million dollars. >> police also discovered that jeff was the beneficiary of cathy's $29,000 life insurance policy. >> he was making restitution for prior criminal activity. i think he was tired of making those payments. >> in a search for forensic evidence, investigators had the presence of mind to confiscate the clothing jeff was wearing the day of the murder. a forensic analysis found no blood on the shirt and boots. but blood spatter expert stewart

james examined the jeans. section by section under a stereo microscope. >> well, the dark color of the jeans certainly made it more difficult to see blood. >> but at 60 times magnification, james could see things invisible to the naked eye. deep within the fabric on the jean's left leg near the inside of the thigh, james saw tiny specs of what appeared to be blood. >> the suspected blood stains were actually down within the weave and between the weave of the fabric, which indicated to me that these stains were not the result of transfer, which would have just been on the top of the weave, but rather driven into the weave much more consistent with impact spatter. >> the blood spatter was the

same size and shape as one would expect to find after inflicting a beating with a blunt object. dna testing of this blood revealed it was cathy lamb's blood. >> we had impact spatters at the scene on the wall, and we also had impact spatters on the left interior thigh area of the dark jeans of jeffrey lamb. >> this was definitive proof jeffrey lamb struck the fatal blows. and blood spatter expert stewart james found one more thing. >> he just happened to reach into one of the pockets, just checking to see if there was anything in there, and he found an earring, a little diamond earring that belonged to cathy. and jeff told investigators that those earrings were missing. >> investigators now had

book on expedia before march 16th and save up to thirty percent. two months after cathy lamb's murder, a worker found a tire iron on the roof of his building. >> he was on the roof because it had been leaking over the tow company. and he found a fire tool that

was used on one of their big, big tow trucks. >> it was the office building of the tow yard where jeff lamb worked. the tire iron had hexagonal heads for loosening and tightening nuts. it was tested for dna. >> we tried everything to test the tire iron, but it was south florida and it rains all the time. the sun would have evaporated any dna as well as the water washing it off. >> but since it was so distinctive, as were the wounds on cathy's body, the tire iron was still a valuable piece of evidence. the hexagonal head was placed over photographs of cathy lamb's wounds. >> you look at the injuries on cathy's face. there's no way in the world anything other than this did it. >> jeffrey lamb was arrested and charged with first-degree murder. prosecutors believe jeff wanted

out of his marriage. he often told friends that cathy was a poorhouse keeper. but apparently jeff was no better. >> he called her dirty and yet his truck was filthy. he had more garbage in his truck than you would throw out in the street. i don't know if you would call him a hypocrite or something, but he didn't lave better lifestyle than his wife. >> the couple separated for a few years, but even after they reconciled, jeff continued to have affairs. cathy tolerated his infidelity, but she didn't like it. >> i felt very sorry for cathy. i felt very bad because i knew that she loved him very much and i thought she would be very hurt over that. >> jeff was paying off a $20,000 fine for embezzlement, and a divorce would have left him with even less money to make those payments. >> jeff had a friend. he had told him that i'm not going to lose my stuff and i'm not going to give up her life insurance policy. i'll kill her before she

divorces me. >> prosecutors believe jeff planned to use cathy's life insurance proceeds to start a new life with his fiancee. on the afternoon of the murder, jeff was at work. his fiancee's car was at the tow yard for repairs. according to co-workers, jeff said he was taking the car to get gasoline and left sometime between 4:30 and 5:00. the evidence suggests he went home, waited for cathy to return from work, and when she did, beat her to death with a tire iron. in the process, he got blood spatter on his jeans. the dogs didn't attack him, but in their agitation, they attacked each other. to separate them, he hit cathy's dogs and took his dog bandit

into the bedroom and closed the door. he took cathy's diamond earrings to make it look like a robbery. one of those earrings was later found in his pocket. jeff changed his shirt and shoes but not his jeans. he probably didn't see the blood on them. jeff's friend lisa called him on his cell phone just after 5:00 p.m. the call bounced off a cell tower near jeff's home, proving he wasn't at work as he had claimed. there was no evidence lisa new anything about the murder. when he returned to the tow yard, he threw the murder weapon up onto the roof thinking no one would ever find it. >> it was planned. he took my daughter from us, her

family, and her friends for $29,000. >> in september of 2006, jeffrey lamb was convicted of first-degree murder. he was sentenced to life in prison without parole. >> we were confident going to trial because the case wasn't just based on science, it was based on common sense. >> i don't believe he gets up one morning of one day and says how could i have done that to that human being? besides the fact that she was my wife, besides the fact that i have known her since she was a teenager. >> his first mistake was not to change his clothes after he killed his wife. the second mistake would be throwing a tool up on a roof where it doesn't belong and somebody may discover it.

>> his clothing was the key to the case. if the detectives had not asked him to remove his clothing, we could never have convicted him of a crime. he definitely would be walking free today fest. >> and at some point, he was >> that was definitely a staged scene. >> one of the best defense lawyers in san antonio, texas, was leslie vaughn. >> leslie was a workaholic. if you know anything about guys who tried to reach that status of perfection, leslie was a perfectionist. he really was.
