Gilgo Beach Murder Investigation Timeline: Police Arrest Rex Heuermann

• The hunt for a suspect in the Gilgo Beach killings culminated this week in the arrest of Rex Heuermann.
• Police have found the remains of 10 people and a toddler near Gilgo Beach on Long Island since 2010.
• The arrest of Heuermann came after police announced a new joint task force last year.

For more than a decade the Gilgo Beach murders remained a mystery. But this week police said they finally found the man they think is responsible. Police arrested Rex Heuermann, 59, at his home in Massapequa Park, New York. He is an architect who is married and has two children, according to a neighbor.

The grisly story of the murders began more than a decade ago. Here’s a timeline of the Gilgo Beach murder investigation.

May 1, 2010: Shannan Gilbert goes missing

After visiting a client she met on Craigslist, Shannan Gilbert, who earned a living as a sex worker, did not come home. In a more than 20-minute 911 call placed just before 5 am on May 1, the 24-year-old said her life was in danger. She then knocked on the doors of multiple residents in the Long Island town of Oak Beach. Witnesses said she appeared incoherent and afraid before running off.

Gilbert’s family later filed a missing person report, CBS News reported, triggering a manhunt.

December 2010: Remains found on Gilgo Beach

While searching for Gilbert, police discover the bodies of four other women along a highway between Cedar Beach and Gilgo Beach in Long Island, not far from where Gilbert was last seen. But Gilbert herself is not found.

The four women, whose remains were found in burlap sacks, also worked in the sex business. They were later identified as Megan Waterman, Maureen Brainard-Barnes, Melissa Barthelemy, and Amber Lynn Costello. All had been missing for years.

At the time, police downplayed concerns.

“I don’t want anybody to think we have a Jack the Ripper running around Suffolk County with blood dripping from a knife,” Police Commissioner Richard Dormer told a local NBC affiliate.

April 2011: More bodies found

Police continue to find more potential murder victims, announcing they had found a 10th set of human remains in the area around Jones Beach State Park. The remains included those of a toddler, The New York Times reported.

But they were no closer to identifying a perpetrator.

“Right now, it could be anybody,” Det. Lt. Kevin Smith told a local radio station.

December 2011: Shannan Gilbert’s body found

Police divers find Gilbert’s remains in marshland near Oak Beach. But authorities differed on whether she was a victim of the same person who killed the other women, CNN reported.

“The theory is now that we’re dealing with one serial killer,” Police Commissioner Richard Dorner said at the time. But at the same press conference, Suffolk County District Attorney Thomas Spota pushed back, saying “I don’t know of anybody” who believes all were killed by the same person.

July 9, 2013: ‘Lost Girls book published

Jan. 16, 2020: Authorities reveal new evidence

March 13, 2020: A film about disappearances released

Streaming platform Netflix released “Lost Girls,” a film based on the earlier published novel about the disappearance of Gilbert and several other women around Gilgo Beach. In an interview, actress Amy Ryan, who stars as Gilbert’s mother, said she hoped the production would help bring a resolution to the case.

“If some justice could be brought for the families, that would be such a success for the film in my eyes,” Ryan said.
