A timeline of the investigation of the Gilgo Beach killings

By The Associated Press

Starting in 2010, police searching for a missing woman found 10 sets of human remains in the scrub along a barrier island parkway near New York’s Gilgo Beach. Police almost immediately feared some were left by a serial killer. Over the years, investigators used DNA analysis and other clues to identify the victims. In some cases, they were able to connect them to remains found elsewhere on Long Island years earlier. Prosecutors have charged a Long Island architect, Rex Heuermann, in six of the deaths. One of the alleged victims was killed in 1993.
