Summary of what I have learned so far - he had season tickets to the Celtics and went with a friend/co-worker, he had been drinking heavily and left unexpectedly in the 3rd quarter, he told his co-worker he would meet her after the game at her car, he was in contact with her while he was outside and didnt seem to know where he was but seemed ok, at some point he tried to call an uber, his phone went dead between 10-11pm Wednesday about a mile away from the Garden (where the Celtics play) on Tremont Street. He lived pretty far away but eventually after not hearing back from him she just went home. Nothing since.
edit - i initially thought they were saying he was with two people, now it sounds like he was with just one person, a woman - does it sound weird to anyone that he took a woman with him to a celtics game, got really drunk, got up and left unexpectedly during the game and told her he would meet her after the game, and she stayed and watched the rest of the game? im sure this can and will be confirmed by cameras in and around the garden, it just strikes me as odd.
It is odd and reminds me, too, of the Morgan Harrington case a few years ago.
