When Shannon Gilbert went missing in Long Island, her disappearance was largely ignored by the media and police. That is, until months later when the remains of other sex workers were discovered nearby — but none of them were Shannon. What happened to her? Who was targeting these women? And why weren't police doing more?  Journalist Bob Kolker, author of Lost Girls, investigated Shannon Gilbert's story and the institutional failings that plagued these women's cases. He joins us this week on Crime Story, providing updates on the investigation, including a recent arrest.  For ad-free listening to Crime Story, subscribe to CBC's True Crime channel on Apple Podcasts.
