detectives shirts the towards home, they found no sign of a forced entry just an unlocked side window. and inside the house, once again, no forensic evidence. but a different pattern. the killer had taken his victims with him. >> we don't know if they were killed inside the house and transported away, or if they were just transported away and killed elsewhere. >> the burned out nissan maxima that carried the mother and daughters bodies didn't yield any significant clues either. the fire had destroyed everything but a tiny piece of jeans on dolores his body. and attached to the jeans, some leaves foliage experts identified as coming from a beach tree. odd because there were no trees like that in the neighborhood. and the mystery only deepened when the autopsy results came back. >> ebony and dolores were actually killed 24 hours prior to them being burns in the car. that was another hiccup in the case. where were these two bodies kept for a full day?

>> it seemed the debates killer took immense risks to get rid of the bodies. >> you're talking about taking two women out of their house and transporting them to another location and then stealing a car, putting those dead bodies in the car, driving past the house that you just stole the car from, and then parking in a driveway of a vacant house, that setting that car on fire and walking away. >> and the autopsy also revealed that tillerson ebony were strangled, not shot as the lofted's had been. it was a puzzle. were they dealing with a serial killer are not? >> did you think one guy was responsible for both these crimes? >> i would go back and forth. one day i would -- it was all in that it was the same person. the next day, i thought it wasn't. because both crimes are so different. >> then finally the detectives caught a break. they learned that a month before the dewitt murders, the owner of the stolen we saw maxima had been the victim of a break in.

she reported it but at the time, told the police that nothing had been taken. now she noticed that her spare set of car keys was missing. >> so tony, as i understand your detective logic goes something like this. if i can find the person who broken who stole the key but then use the vehicle to transport the bodies i'm getting close to my killer. >> exactly. it gives me direction to where i can find the killer. >> 200 police officers blanketed the area and brought in more than 80 people for questioning, all to no avail. for many prince george county residents, home invasion victims vicky and lloyd urban that man only one thing, panic. >> it was crazy. i couldn't sleep at night. any sound, i had alarms put up throughout the entire house and plus we got the dog, -- >> and bars on the windows. >> yes. >> the house was turned into four knocks. a barking crazy dog who closet the windows if he hears a doorbell ring. there was no peace in the house. i was like, we have to turn some of this stuff down.

i can't live like this because he's, like i don't care if this is going to save our, life you know? >> just the fear that spread was absolutely amazing. >> by july 2009, four months after the debate murders and six months after the lofted murders, detectives were stumped. >> we kept calling them and they weren't giving us no answers so that pisses me off because i felt like we deserved to know something. >> it was wild. we had nothing. >> we were out of the investigative playbook and that's when it got scary. >> the detective had made a promise to patricia that he would take down her sister's killer. with that turnout now to be an empty promise? at this point, what he needed was luck. and luck was about to come his way from the most unexpected source. coming up, an unassuming neighbor comes forward with some unbelievable information. >> at that point we realize that our investigation just took a drastic turn. >> when dateline continues.

investigators wondered, was he afraid of jason? >> another former coconspirator was telling investigators jason was no one to cross. >> he's sensitive. you gotta watch how you talk to him. >> these guys would say, if i ever got into a fight with jason, jason you know one fight me, back two years later he be the type of guy to come back and burn my house down. >> that's the type of duty, was he's. crazy >> three weeks after is king for a day deal, jason scott was still walking the streets. investigators knew an off about him to worry for their own safety. >> his mo was, he would specifically go and cut the power to these homes, caught the fire alarm so one night sleeping, and i kind of become aware that all the sudden the power is off in my house. so knowing that jason knew my name and thinking he could figure out where i live, i actually grabbed my gun and proceeded to tactically clear my house. just to make sure that he wasn't the reason for the power being out. as i worked my way through the house and into the kitchen, i finally came up and i noticed

that in the backyard, the entire neighborhood is dark. at that point, i take a sigh of relief and i realize it's not him. but that's how concerned i was. he is that dangerous of a guy, that i recognize he needed to be in jail. >> if jason scott was smart, the task force simply had to be smarter. and investigators notice jason did not seem to understand an important legal nuance. his proffer did not guarantee him complete immunity. the cops could not use his own words against him, but they could use the words of others. so one investigators found that other accomplices of jason's, they grilled him. >> do you know of him to break into a house and just take carcass? >> yeah he talked about one job, a couple of jobs going in and take the keys and just have just in case he needed the car. >> these details eerily mirrored what happened in the dewitt murders. >> he likes to steal car keys, spare keys.

he likes to come back later and get that car. >> that was exactly the case with the nissan, right. >> first. check he likes to park carson vacant houses, preferably houses that were for sale. >> again the torched car with the bodies, was a vacant house that was up for. sale >> detective nelson nail down several connections between jason's got in the first mother daughter murder. the law often. 's most important of those, jason's car, a dark blue toyota kammuri. it matched the description of the mysterious car one of the law often's neighbors had seen. >> that could very well have >> that could very well have been the vehicle the neighbor had seen the night of the killing. >> then investigators discovered another sticking piece of evidence, a video jason made of the victims of one of his home invasions. a mother and her teenage daughter. >> he brought her into her bedroom instead of a video camera. and in the process of setting up the camera in which he was going to, basically film him self sexually assaulting her, the kim and happen to pan right

to his face and the screenshot showed us this. wow. >> this is what a lot of justin 's victims. saw it's cold, calculating eyes, lifeless. >> investigators were shocked. even more so when they dug up the old police report and notice with the perpetrator they now new to be jason, ed blurted out to the mother and daughter just before he left. >> okay. here it is. >> he said he didn't to hurt us, but he said he was supposed to kill us. >> yet all the evidence was purely circumstantial, not enough to charge, let alone convicted jason with murder. that was about to change. and it had to do with the one case police had plenty of evidence for, the weapons theft. when the agents talked to jason's about it, he mentioned the spooky house, an abandoned building off to be in path and upper marlborough. he said he is a complicated sweat to divvy up dilute.

detective shark never had a spooky feeling he'd bought more than guns there. >> we're still trying to find the place or house or whatever where the do its were stored or kept for those 20 someone hours. >> so this spooky, house whatever it, is could be the place. >> absolutely. >> and according to jason's proffer, if his statements led to new evidence, that evidence could be used to prosecute him. >> mice thirst thaw and impressions were that this is going to be like, and old rickety alice, maybe even falling apart. >> it doesn't feel like we're heading to spooky house, guys. >> it wasn't until we came here, that we realize there is a long driveway here that maybe made sense. >> there it, is when? >> the spooky house was a georgian mansion up for sale, like the property where the nissan was set on fire, vacant.

what a hideaway to do whatever you want to do from prying eyes, have? >> absolutely. and at night this is absolutely pitch. dark this is just a playground the jason sky had. >> the task force called in the forensic team. >> we walk down here through these rocks here and that's when i first initially saw the sweater, which was right down here in the rocks. >> it was the charred remains of a blue sweater, the kind ebony dewitts had worn the last time she was seen alive. >> once we saw, that we said hey this is it this is finally, something you were talking about a high five moment. you walk further down these rocks here, and gathered in these leaves where the other two pieces. >> jeans that seem to match the gene fragments covered from dolores dewitt body. -- detective sharpen are brought

in expert to the spooky, house to identify the foliage. >> and he pulled up here and he said, this is the jackpot of beach trees. >> poor ebony and her mom were here. no question. >> without a. doubt >> but to arrest jason, vest gaiters needed more. so the heat they eliminated is complicit as a murder suspect, so they hear him up again into jason is talking, if you don't, you'll be the want to take the fall. that did it. marcus hunter finally agreed to cooperate. right away he dropped a bombshell about jason. the specter of him becoming a monster grows with each and every stone we overturn. >> coming up. >> i think he truly thought he could outsmart us. >> could? he >> wouldn't take to put jason behind bars? when dateline continues. this is what people with eczema said about how their skin feels...

scott walked out of the prosecutor's office, with the potential stay out of stay adjala delight hand. -- to cooperate. the king for a day was about to be dethroned >> so marcus tells us a month earlier, prior to the dewitt family being killed, jason and here running through the backyard on a job. and jason stops and looks into the do its house and notices ebony, and he starts to stare at her. marcus gets uncomfortable and says, hey we can't stay here

all. night we need to go. >> much more damaging, the accomplice told the task force that after yet another robbery, and approximately an hour before dolores and of any were killed, he'd given jason a ride to his car, parked just a block or so from the dewitt house. in the accomplice had more. >> he said there was at one point and it was during the time that the law often's were murdered, that he had seen jason scott for a short timeframe, with a glut 17. >> a glut 17. the very weapon used to murder karen and carris. >> i had one of our investigators try to find out who purchased glut 17's of the last two years, and then contact those people and find out if they can account for their handgun. any found out that a home was

broken into 13 days before the law often's were killed, and during that break in, they're glut 17 handgun was stolen. >> and here is where detective nelson got lucky. the state of maryland requires handguns to be test fire before they are sold so it can archive eats gun shell casings to help identify, or trace the weapon should it be later used in a crime. >> we immediately took out the shell casings and had them compared to the known shell casings from that known handgun. and during that testing, they were able to verify that all six shell casings came from that one particular glut 17. that was the weapon that was used to kill both of my victims. once we found out where the murder weapon came from, that was used to kill the lofton we need to find out of jason's guy ever had that gun in his hands. we asked his accomplice marcus hunter if they ever broke into a house in this one particular neighborhood.

he said they did, it was only one house. we never told him which when it was and he looked took us directly to it. the house that the glut was stolen from that killed the law often's. >> this far as the handgun goes, i think that was the nail in jason's coffin. we know he stole that weapon. >> did that solve the lofton murders? >> it got us as close as we are going to. get >> detective schatner and melted arrested jason's at his home in 2009. >> i remember telling him jason take a look at your house, this is last time you will see. it >> he didn't have a response, he just gave some type of noise. smacking his lips of if i'll be back. >> i think he truly thought he could outsmart. us and fortunately for bernie and i and the two agents from the atf we outsmarted him. >> and personally, the takedown of jason scott made the detective a promise keeper.

>> he said i am going to get him. if it's the last thing i do. he said i am going to get him. and he got him. >> in exchange for his cooperation, marcus hunter got a reduced seven year sentence for weapons possession. it would be another three years before the atf and county police analyzed all the evidence against jason scott. when all was said and done he was sentenced to 185 years in prison. >> one of the things that the judge said, and i'll never forget this, he said you're not even a crime wave year a tsunami of crime. >> the satisfaction take down a guy like? this >> extreme. >> it was the proudest moment in my career. >> but just did cut one final deal. in exchange for acknowledging the prosecutors had enough evidence to convict him for the dewitt, the state agreed not to prosecute him for the lofton. that did not sit well with the lofton family. but that's the best investigators thought they could do. >> the bottom line is we know

jason is gone forever. he only has one life to give. we cannot punish him anymore than what he is already being punished. >> this serial killer, the master robber and burglar, will likely die behind bars. the neighbors he terrorized are safe again. but under some roofs, there's been damage to the concept of home as a sanctuary. take vicky in lloyd ervin. they've kept their burglar bars their home alarm system, they didn't know how much they needed that stuff until we fill them in. >> let me tell you something that, will probably freak you out in this comes from a guy number two in your house. he said, after the home invasion they came back. >> are you serious? >> he wanted another round, they parked in front of your place, did a little surveillance, sculpted out, and jason scott wanted to come back in and even the score. >> i didn't know that, that's scary. >> could've been your picture on the 11:00 news. >> that's. right >> how does one person

cause so much damage and so much her in so much loss for so many people? it still blows my mind. >> that's all for this edition of dateline thank you for watching. coming up on the mehdi hasan show. -- top republican still pre-trump, but new reporting shows that we know that they know who he is. new details on kevin mccarthy's and mitch mcconnell's outrage after the january 6th attack on the capitol. plus the fight for the senate! we'll look for the billion dollar battle that shows there is no -- in politics. and the escalation of violence in israel in the occupied territories, is easily similar to last year's war. i'll talk to the prime minister about what we know about the ongoing occupation.
