Cop in Amber Guyger case who asked dashcam to be turned off speaks out
The Amber Guyger murder trial may be over, but the investigations continue. During the trial, the Dallas Police Department was accused of misconduct during the Botham Jean murder investigation. A surveillance video entered into evidence shows Sgt. Mike Mata lean into the patrol car that Guyger was sitting in, and tell another officer to turn off the dash cam. Prosecutors allege he was trying to protect Guyger and hide evidence.
