UPDATE 1:30 pm EST:

The Associated Press is reporting that the FBI is at the New Jersey home of the alleged Boston Marathon bomber’s sister.  Authorities say that she has been cooperative and that there are no reports that she was involved in any of the attacks.

Speaking to reporters through the crack in her door, she responded when asked if she was okay:

“No I’m not okay – no one is okay right now,” she said. “I’m hurt for everyone who has been hurt. I’m sorry for all the people who are hurt and for all the people who lost their lives.”

She commented on her brothers, whom she said she had not seen in a few years, according to the Star Ledger in NJ.

“They were great people. I never would have expected it,” said the woman, of the suspects in Monday’s bombing. “They are smart – I don’t know what’s gotten into them.”

 

UPDATE 11:40 am EST:

In a press conference with reporters this morning, Ruslan Tsarni, the uncle of the alleged bombing suspects, spoke in terse words about his nephews.

“What I think was behind it: Being losers,” the men’s uncle, Ruslan Tsarni, told reporters from Montgomery Village, Md. He encouraged his nephew to turn himself in and said the two had brought shame on Chechens. He said that he had encouraged his own family to stay away from that part of the family.

“Of course we’re ashamed,” he said.

Additional interviews are available here and here.

If you’re just catching up this morning on all the activity that occurred overnight in the hunt for the remaining Boston Marathon suspect, here’s the latest since our last update early this morning:

Watertown, MA remains on lockdown after a convoy of law enforcement personnel drove into the town and surrounded the immediate area.   Police have been going door to door to warn residents to remain inside, keep their doors locked and to stay away from windows.

At about 10:20am EST, Boston Police issued an alert for a 1999 Honda CRV with MA license plates; shortly thereafter, that was updated to indicate that the car had been found unoccupied and is being processed for evidence.  Police also distributed an updated photo of 19 year-old alleged bombing suspect Dzhokhar Tsarnaev, indicating that he is armed and dangerous.

Mass transportation in and out of Boston remains virtually shut down, although air travel at Logan International Airport is said to remain operational.  Highways in the Watertown area are said to remain closed.

NBC News has also compiled a helpful timeline of events.

A press briefing is scheduled to occur momentarily.  More updates as they become available.
