State's Attorney Marilyn Mosby is defending the prosecution of six officers charged in the Freddie Gray case and says she still blames police for the young black man's death. Mosby spoke Wednesday near the site of Gray's arrest in April 2015. Her comments came after prosecutors told a judge that they were dropping the remaining charges against three officers. Three other officers were acquitted. Mosby says prosecutors do not believe that Gray killed himself when he was handcuffed and shackled in the back of a police van and stand by the medical examiner's finding that his death was a homicide. She declined to take questions, citing a lawsuit the officers have filed against her. The prosecutor, Marilyn Mosby, announced earlier in the day that she was dropping charges against the remaining officers awaiting trial in the case. In a fiery defense of her prosecution, Mosby blamed police for an investigation that failed to hold anyone accountable for the death of Gray, a young black man. Gray's neck was snapped in the back of a police van, and he died a week after his injury. Mosby says she stands by the finding that Gray's death was a homicide, saying "we do not believe that Freddie Gray killed himself."
