Unless the police know something that we don't, it could be because of the circumstances; he had no enemies, and no other risk factors for running away or leaving his family.
Also, he was at a bar, which can be seen as a fairly high-risk environment. It seems that he vanished between the bar and a street corner where he was going to meet his mother, in a fairly built-up area.
I wonder if he was hit by a drunk driver leaving the bar, who moved his body, or he got into a minor scrap with someone that escalated when they caught him alone.
