Gilgo Beach Killer's Confession

Asa Ellerup, the former wife of Rex Heuermann, shared the details of his confession in a teaser for a new Peacock documentary.

Heuermann allegedly admitted that the majority of his victims were killed in the basement of their Massapequa Park home while Ellerup was away.

The disclosure provides a chilling new look at the crimes that haunted Long Island for over a decade.

Investigators are now reviewing the home for additional evidence that may have been missed during previous searches.
