The arrest of suspected Gilgo Beach killer Rex Heuermann could mean justice for an unknown number of additional victims thanks to a key piece of evidence: Heuermann’s DNA, NYPD sources told The Post Saturday.
The department plans to compare the accused serial killer’s genetic material — obtained from
a discarded pizza crust, then matched to DNA found on the body of victim Megan Waterman — against its backlog of cold cases.
“His DNA was never in the system until they arrested him,” the source said. “Now we can compare it to other crimes.”
