Suspected Gilgo serial killer Rex Heuermann had a summer job that police say primed him with knowledge about his alleged chosen dump site for victims' remains.

The hearing was focused on the use of DNA evidence and whether there would be one trial or separate trials. One of the victims was from Scarborough.

Lawyers in the Rex Heuermann case continue to mount arguments on whether to throw out DNA evidence and hold a separate trial for some of the charged murders.
