Pretrial motions are scheduled to begin for the fifth Baltimore police officer facing criminal charges in the arrest and death of 25-year-old prisoner Freddie Gray whose neck was broken in the back of a police van. Officer Garrett Miller faces assault, misconduct in office and reckless endangerment charges. Prosecutors say Miller illegally arrested Gray and was negligent for failing to buckle Gray into a seatbelt or call a medic when he indicated he wanted to go to a hospital. So far, four other officers have gone to trial for Gray’s death. The trials ended in three acquittals and one mistrial.
