Why no comment on where he was picked up at such an hour and to head downtown when everything is closed is a big question. If he was picked up a possible business, I would think such a late night establishment would have some sort of surveillance. Or the cab company has a residential address and phone number of where they picked him up and what number was used for the call. But thats all basic investigative research. More answers to come I should hope. Also most cabs now a days have video surveillance to boot..
