Prosecutors dropped the remaining charges Wednesday against three Baltimore police officers awaiting trial in the death of Freddie Gray, bringing an end to the case without a conviction.
Gray was a black man whose neck was broken while he was handcuffed and shackled but left unrestrained in the back of a police van in April 2015.
Prosecutors had said Gray was illegally arrested after he ran away from a bike patrol officer and the officers failed to buckle Gray into a seat belt or call a medic when he indicated he wanted to go to a hospital.
His death added fuel to the growing Black Lives Matter movement and caused massive riots in Baltimore.
The decision by prosecutors comes after a judge had already acquitted three of the six officers charged in the case, including the van driver and another officer who was the highest-ranking of the group. A fourth officer had his case heard by a jury, who deadlocked and the judge declared a mistrial.
