In news from Baltimore, the prosecutors who failed to secure convictions for police officers after the death of Freddie Gray say the city’s police department undermined their case. Prosecutors Michael Schatzow and Janice Bledsoe say police failed to serve search warrants for police cellphones that would have offered evidence of how officers reacted after Gray’s death. Gray died in April 2015 of spinal injuries after he was arrested and transported in a police van. Six officers faced charges related to his death, but prosecutors dropped all remaining charges against three officers Wednesday after failing to win convictions for any of the first four officers to go on trial. Five of the officers have also filed suit against Baltimore City State’s Attorney Marilyn Mosby, alleging defamation and unlawful arrest.
