Freddie Gray died eight years ago of a broken neck, but just how has never been clear. Investigative reporter Justine Barron presents new evidence -- about the arrest of Freddie Gray, the investigation and the prosecution -- in her book, "They Killed Freddie Gray: The Anatomy of a Police Brutality Cover-Up."

Barron will be speaking this Thursday at Red Emma’s Bookstore Coffeehouse. RSVP here. On Sept. 2 she’ll discuss the book with Johns Hopkins University professor Stuart Schrader at Charm City Books.

Clarification from Sheilah Kast:

Investigative reporter Jayne Miller said my question to Barron was incorrect, in summarizing that Miller had reported it was possible that Gray broke his neck when police threw him headfirst into the van.

Miller interviewed a witness on WBAL April 17, 2015; the witness said she had seen police throw Gray into the van face down, head first, ankles bound, arms bound. Miller reported, “It is not known if Gray’s injury, a broken neck, occurred at that point. He was in the police wagon another 30 minutes, according to a police timeline, before medics were called.”

That was one of Miller’s reports on Freddie Gray that won a prestigious Alfred I DuPont-Columbia University Award.
