 Police say Mitchell caused a disturbance at a Hyatt Regency location and got into a struggle with security guards as they escorted him out. Video posted online appears to show the guards leaning their weight onto Mitchell, who was face down on the ground. Witnesses say the struggle lasted at least 10 minutes. When police arrived, Mitchell was unresponsive and declared dead. A cause of death is pending, though the local coroner has ruled it a homicide. The security guards involved in the incident have been suspended.
