Word is they evacuated a 5 block area around either the guy's home (or the home of his parents?) and wouldn't tell the people why.
Some other parts of town were also evacuated for unstated reasons.
After the guy blew himself up, one of the local news stations went to his parents' house and talked to them - before the police got there! (Cops were right on top of this, eh?)
Parents claimed their son had moved out "years" before and had a roommate. Denied all knowledge that their kid was a mad bomber. Neighbors interviewed said the family was quiet and kept to themselves, never causing any trouble, and the mad bomber seemed just like a typical neighborhood kid as he was growing up.
Too bad the bomb that blew up the guy wasn't the first one to go off.
