Accused Gilgo Beach serial killer Rex Heuermann is charged in the murders of seven women, but his attorneys say DNA results from hair found at six crime scenes should be excluded from the trial. Heuerman's attorneys are asking the presiding judge to exclude expert testimony related to nuclear DNA results from hairs found at the crime scenes.
