He got away from that many policeman and FBI agents?
There's always the possibility that this cat is well out of town, by now. In the past 8 hours, or so, he could be 20 miles down the road. I'm not familiar enough with the Boston area to know for sure, but I bet 20 miles would put him in a rural area, with even more hiding places.
