I'm not saying anything like this happened, but time for a CSB ...
I know a guy who was charged for this exact thing a few years back.
He and his wife were drunk late one evening and had an argument at their house. She started to get violent. He was trying to restrain her from hitting him and was holding her arms with his hands when they went to the ground. While still holding her wrists in his hands, his forearm ended up across her neck which was enough for her to stop the struggle. When he let her up, she locked herself in a room and called the cops. They arrested him on this same charge and he spent the night in jail. The next day, when everyone was sober, he realized he should have just left the house and she realized that she overreacted in accusing him of choking her (she told me this directly). The charges ended up being dropped and after some counseling they are still married and have put it behind them.
All that to say, we do not know the facts yet, so I will reserve judgement until they come out. Once they do, if he really did strangle someone, he needs help and jail and a new career.
