ABC: Boston terror suspect awake and responding to questions in writing

BOSTON - The surviving suspect in the bombings of the Boston Marathon is awake and answering some questions, ABC News reports.

The network tweeted that Dzhokhar Tsarnaev, 19, "is awake and responding sporadically in writing to questions…"

"They are asking about other cell members and other unexploded bombs," said a second tweet.

The information in both tweets was attributed to law enforcement sources speaking to ABC correspondent Pierre Thomas.

In the days following Monday's bombing, Tsarnaev was reportedly seen on campus at the University of Massachusetts Dartmouth, where he was a student.

Photos of Dzhokhar and his brother, Tamerlan, were released by the FBI Thursday, before their identities were known. That night and into Friday morning, the brothers allegedly engaged in another series of violent events with a carjacking, the fatal shooting of an MIT officer and a chase with another shooting that resulted in a transit officer being seriously wounded and Tamerlan being killed.

Dzhokhar was able to escape that shootout and elude the manhunt for several hours before he was found hiding in a boat stored in a backyard in Watertown, Mass.

Somewhere along the way, Dzhokhar was shot in the throat. As a result, he may never be able to speak again.
