Fmr. FBI official surprised Boston bombing suspect has eluded capture

It has been hours since the deadly shooting that killed one of the Boston bombing suspects, 26-year-old Tamerlan Tsarnaev. Yet one other suspect, 19-year-old Dzhokar Tsarnaev, is still on the run, despite the high number of law enforcement officials that are hunting him. Former Assistant Director for the FBI Bill Gavin said he is surprised the younger brother has eluded capture.

"It is surprising nobody has seen him run into a backyard, or into any place where they could get their hands on him," said Gavin.

"My concern is whether or not this young man, the 19-year-old, took maybe a couple rounds, because a lot of bullets went into that car and into his brother," Gavin said, referring to the deadly shooting that took place in suburban Watertown, Boston early Friday morning.

"I don't see how he escaped with having none, and I just wonder if he is gone to nest someplace and [bled to death], that would be a concern of mine," said Gavin.
