If it weren't for the pictures of the bruises on her face, I'd be a little more inclined to think that maybe it is possible she harmed herself. Is it not possible the cop turned off the camera innocently, although it does look like he put something over it. Maybe he left her alone and being somewhat distressed for having just put someone in hospital for being drunk at the wheel, she tried to take her own life. Maybe she somehow managed to slit her wrists on something.

Otherwise, looks like the cop is a woman beating scum bag and probably deserves to be imprisoned and tortured in a hard labour camp for 10 years.
