RIVERHEAD, N.Y. -- Suspected Gilgo Beach serial killer Rex Heuermann is scheduled to return to court Wednesday on Long Island. The 61-year-old is charged with the murders of seven women dating back to the 1990s .

The office argues nuclear DNA science is "generally accepted" within the scientific community and "based upon technology that has been implemented for decades."

Rex Heuermann’s attorney said in court Wednesday that the DNA technique used by a lab to allegedly link Heuermann to the Gilgo Beach serial killings is essentially “magic,” not science, and should be thrown out as evidence in the Long Island case.
