A defense attorney for accused Gilgo Beach serial killer Rex Heuermann wants to block prosecutors from introducing DNA analysis they say links her client to the killing of 6 women, arguing that the technology is in its "infancy" and falls "far short of the general acceptance required by law," according to a motion submitted Friday.Suffolk County investigators employed Astrea Forensics, a California laboratory, which tested rootless hair samples found on the women’s bodies and used statistical analysis to compare those hairs with DNA samples from Heuermann and his family members.
DA Tierney said that the lab had connected the architect, his wife Asa Ellerup and their adult daughter to strands discovered on the remains of Maureen Brainard-Barnes, Megan Waterman, Amber Costello, Sandra Costilla, Jessica Taylor and Valerie Mack — six of the seven alleged victims.
Danielle Coyish, who is defending the Massapequa Park man charged with the killings, argued that Richard Green, the co-founder of the lab, has a financial stake in promoting the new forensic methodology — called IBDGem — used to establish the match, creating a conflict of interest.
"Admitting such evidence would improperly shift the burden from the State to the defense and risk prejudicing the jury with unreliable scientific claims," she wrote in her brief.
Prosecutors have until Aug. 22 to file their response. The judge has promised to rule on the issue by Sept. 3.
The prosecution says the analysis connects Rex Heuermann, his ex-wife and adult daughter to hair discovered on the remains of six victims.
