If nuclear DNA evidence is allowed in the trial of accused Gilgo Beach serial killer Rex Heuermann, it would be a first for New York.
A lab used the new technology to link hairs on several victims to Heuermann. That lab's founder, University of California scientist Dr. Richard Green, testified in court Tuesday.

'If nuclear DNA evidence is allowed in the trial of accused Gilgo Beach serial killer Rex Heuermann, it would be a first for New York. A lab used the new technology to link hairs on several victims to Heuermann.'
Apr 10, 2025 #CourtTV
Attorney Michael Brown, representing accused serial killer Rex Heuermann, discusses their ongoing battle over DNA evidence in the case.
''Investigators found DNA belonging to Heuermann's now estranged wife, Asa Ellerup, in hair recovered from a belt used to restrain Brainard-Barnes, according to the indictment. Heuermann's family was out of state when Brainard-Barnes was killed, prosecutors said, and Ellerup is not suspected to be involved.
"The DNA itself was extracted from the hair back in 2010," Tierney said. "At that time, there was no method to obtain nuclear DNA profile from hair -- that has since changed. So we're on the cutting edge with regard to using this DNA analysis."
Thankyou so much for this- that was a great article.

I can imagine him as a trail stalker as he has been reported for doing exactly that.
so there is one kind of murder...he could have done that would be a variation. Murders where
he would stalk a victim on a trail and murder the victim outdoors in heavily wooded areas.

Rex is also tall enough to navigate all kinds of terrains and he is strong enough to kill with his bare hands...although we have all heard about his hammer, Rex can trudge right through the tall grasses and reeds and areas that might intimidate others.

also, we have heard the story from the young woman who says she escaped from Rex, where she
went to a townhome with him, an empty townhome with lawn chairs. interesting. Could Ray have
taken women to real estate locations or project locations?

whomever murdered the Atlantic City 4, really went out of their way to leave the victims outside in a very overgrown area behind a motel. watching some footage of the actual hotel, it seems like you would have to go through that hotel to get back to that area. If I remember it was a two level building with rooms at the back where you wouldn't have to drag a victim far to be out of sight.

and then he has his property in SC, where not too many people know him and yet he was identified by the daughter of a missing woman.

so he didn't drag her to his house in LI, no..so he likely has a variety of MO's just as he has a variety of victims and interests. mOO

Adding, that the taxi driver story about Rex waving a gun around, lines up with his interest in guns.
bbm
This!!
"Ray" should be Rex, I assume?
I think, with RH's profession he had so much more opportunities to enter locations/buildings at any time than many other persons would have had.
 
what if this whole time there has been another kill site besides the basement? what could we learn?
I don't trust him not to.

mOO
I am nearly 100 percent positive there were other kill sites. Like this bloodthirsty murderer waited until he had the basement all to himself to kill? Or even the whole of the house, for that matter.
RH was what, 31 yo when he purchased the parents' home? Like RH didn't start killing until he was a 31-year-old homeowner?? Or he didn't start killing until after his first marriage, even?

He's definitely cunning. He targeted very vulnerable victims and by the looks of it made extensive (and infinitely twisted) use of his wife's vacations, and all of his resources and education. But in many respects, he's not at all clever. Like those horrid searches on his computer were a "good idea"? Like keeping clippings from his own murders was a good idea? Like HK doc was a good idea?? Like his weird true crime diatribes with Nikkie Brass were a good idea? He just had to have these things and do these things, he needed them, and that was it, he'd take the risks. Like that mindset sat around waiting for his own basement to start killing? I don't think so. And with the way the outside of that house looks compared to the vehicles he drives, I'd swear that his given vehicle at different junctures played a pivotal role in multiple killings.

Have personally never been 100% sold on the basement as a given for the bulk of cases, but LE clearly feels certain they can prove it for at least one case, so they're going to pound away on that and minimize what they don't know, which is a good strategy. But there is no, no way I think that's going to end up belng the reality, jmo. Where'd he do it, then? Where'd he do this? JMO again, he "switched things up" when he needed to do so. In some cases, maybe he strangled in dumpy motels and transported bodies elsewhere. He's clearly not afraid to transport dead bodies in a vehicle, he had to get to Ocean Parkway somehow. He has his boat. He has his house. He has motels. He has the woods. He has his vehicle. He has storage units. As noted already, he has access to lots of buildings through his work, knows when they'll be empty. He undoubtedly has knowledge of abandoned local structures as well. He has an extensive travel history. He has loads of firearms, yes, I am virtually certain he used those, too-- when he deemed it "appropriate," "most secure option," what have you. He does actual criminology research, and knows there'll be people sitting there until doomsday saying he couldn't have used a gun because it clashes with his m/o. There are more victims, and his basement isn't the only place he kills, jmo.

I would totally agree snooptroop88. For all we know he could have had a rental somewhere to do this when it was not convenient to do it at the MP home. (who was the girl in the NF doc that said she was with him at some sort of townhouse where he went upstairs? has anything ever come to light about that?). I guess you have to think that for him to be able to dismember a body there is going to be alot of mess and its going to stink like high heaven. Not to mention the sound muffling. I do not see how he could have contained himself to just those times when the house was empty either but maybe it is entirely possible he discarded that phase of his life once he saw his children grow up (particularly VH as his only daughter?) Perhaps this may be why AE is completely delusional about his innocence, that she has blocked out something long ago and he has never given her any reason to think anything since ? (just a thought out of the blue here !!)

In a bruising cross-examination performed by Suffolk County District Attorney Ray Tierney that will continue Wednesday, Adams was painted as lacking the credentials and scientific expertise to critique Astrea and its probabilistic genotyping software.

Adams, 38, admitted that it took him about a decade to get his bachelor's degree — prompting state Supreme Court Justice Timothy Mazzei to interject and ask "what was going on in your 20s?"

Agree. Rex is not inflexible. He actually seems to enjoy thinking on his feet.

He even describes himself as versatile tool in that bizarre you tube interview.

MOO
 
Whoa Nellie!
A year ago Bob Macedonio tells Vinnie that AE's marriage was troubled long before his arrest and they had discussed divorce.


LoL, Macedonio blames Rex's bad reputation on the news media lying about his crimes. Really? He certainly sounds like a defense attorney for Rex in this interview.

Basically everything the media has reported has been based on the statements made by LE and the prosecutor's office, as well as legal filings with the court. But according to Macedonio, that's false information, so its ok if Asa doesn't believe it.

She's been able to go into court and hear the evidence against Rex for over a year now. She's been able to read the search warrants, etc., yet she still can't decide if he's guilty.

I'm not sure Chris Cuomo is buying it.

I am interested to know if he had a selection of handguns.
 

"The Gilgo Beach serial killer suspect uttered the words 'good job'
to one of his defense attorneys during the critical murder trial hearing taking place this week.

Defense attorney Danielle Coysh
was given the high praise by accused murderer Rex Heuermann
after she wrapped up her questioning with their expert defense witness Nathaniel Adams,
a systems engineer at Ohio-based Forensic Bioinformatic Services, Inc,
Newsday reported.

Coysh has been an integral part of Heuermann's legal team
and has been working alongside lead attorney Michael Brown since Heuermann's arrest in July 2023."
