My hunch is since it’s been reported by the family the decedent had mental issues and according to reports he assaulted the cop, it’s probably a safe bet he did assault the cop for whatever reason. And when the cop pulled his gun as a warning the decedent failed to heed that warning with all 3 family members jumping in attempting to disarm the guy with the gun. Did the cop announce he was a cop? I dunno.
Btw, the decedent appears to be about 6’6” and someone who could disarm a person rather easily unless he was stopped from doing so.
According to his family he was 6' even.
