An Unsolved Mystery on Long Island

In early 2011, the bodies of four young women were discovered in the brush off Ocean Parkway on Long Island, setting off an investigation into who they were and who killed them. All four women were petite and in their 20s and they all advertised as escorts on Craigslist and Backpage. Award-winning investigative reporter Robert Kolker tells the story of these unsolved murders. In Lost Girls: An Unsolved American Mystery, he reveals who these women were, looks at the shadow world of escorts in the Internet age, and writes about the police investigation.
