Hamilton County Prosecutor Joe Deters sent a letter Tuesday to the UC police chief stating that the officer's action was justified.

His finding comes days after the county coroner reported that cause of death remains unknown for 18-year-old Everette Howard Jr. Howard was on campus for college prep classes and allegedly charged police with balled fists after they responded to reported fighting at a dormitory. Police say an officer used a stun gun when Howard refused to halt. He went into a fatal cardiac arrest.

A message was left for the Howard family attorney, who has said he plans a wrongful death lawsuit.
