Authorities delved more into the arrest of the Gilgo Beach murder suspect who was taken into custody Thursday night in New York City

Speaking at an press conference, Suffolk County Police Commissioner Rodney Harrison said the suspect was arrested Thursday night shortly after 8:30 p.m. ET around 35th Street and 5th Avenue in New York City.

He was transported back to Suffolk County Police headquarters in Yaphank on Long Island, Harrison said.

The suspect in the Gilgo Beach murder investigation, who was arrested Thursday, is connected to the murder of four women who have come to be known as the “Gilgo Four,” according to a spokesperson for the Suffolk County District Attorney’s office.

Authorities initially prompted by the search for missing Shannan Gilbert would come to discover the remains of four other women along a stretch of Ocean Parkway in 2010. All of the women worked as Craigslist escorts, according to officials.

The four women, who were wrapped in burlap and discovered within days of each other, were later identified as Maureen Brainard-Barnes, 25; Amber Lynn Costello, 27; Megan Waterman, 22; and Melissa Barthelemy, 24.

They were last seen between July 2007 and September 2010.

By the time Gilbert’s body was found one year later on neighboring Oak Beach, investigators had unearthed 10 sets of human remains strewn across two Long Island counties.

Authorities later said they believe Gilbert’s death may have been accidental and not related to the Gilgo Beach slayings.
