What did the Long Island serial killer do?

The Long Island serial killer case dates back to 2010, when investigators launched a search for a missing sex worker and found the bodies of 11 women buried along Gilgo Beach.

In 2023, investigators charged architect Rex Heuermann with the murder of three of the victims: Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Lynn Costello, 27. Investigators also named Heuermann the "prime suspect" in the disappearance and death of 25-year-old Maureen Brainard-Barnes.

Authorities began to pinpoint Heuermann in connection with the crimes in 2022. He matched a description provided by a witness and lived and worked near cell-phone sites that synced up with related calls made to the victims via burner phones. What's more, hair belonging to Heuermann's now-estranged wife was found on or near the victims. (His wife and two kids were out of town at the time of his alleged killings.)

Authorities revealed to CNN that they were motivated to arrest Heuermann after growing concern that he was planning another murder.
