 NPR's Ayanna Archie reports the lawyer for Mitchell's family says the use of force in the incident is concerning. 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 is face down on the ground. Witnesses say the struggle lasted at least 10 minutes. A cause of death is pending. The security guards involved in the incident have been suspended.
