BALTIMORE (AP) — The father of Freddie Gray says the family stands by the Baltimore prosecutor who led the case against six officers charged in his son’s death.

Richard Shipley said during a news conference Wednesday that the family “is proud to have her represent us.” 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.”
