From The Baltimore Sun:
The three who face firing are Officer Caesar Goodson, who was driving the van where an autopsy determined Gray suffered fatal injuries; and supervisors Lt. Brian Rice and Sgt. Alicia White, according to sources with knowledge of the case. Officers Edward Nero and Garrett Miller, who made the initial arrest of Gray, face five days suspension without pay.
…The specifics of the charges — and what actions, or failure to act, led to them — is not clear. Davey said the officers are charged with “violations of policy and procedure,” but declined to elaborate.
Officer William Porter — the final officer in Gray’s case — is not facing an internal affairs review, reports the New York Daily News.
