Government officials say Boston Marathon bombing suspect Tamerlan Tsarnaev traveled to Russia last year and returned to the U.S. six months later.

The officials spoke on condition of anonymity because they couldn't publicly talk about an investigation in progress. One says that Tsarnaev traveled out of John F. Kennedy International Airport in New York.

One official said there are no known ties at this point to Chechen extremist groups.

The suspects' uncle, Ruslan Tsarni of Montgomery Village, Md., said Friday that 19-year-old Dzhozkar Tsarnaev should turn himself in to police and ask for forgiveness. He described his nephews as "losers" and said his family is ashamed. "It is an atrocity, we are shocked," he told reporters gathered in his front yard."

Tsami says he respects and loves the United States because "this country gives everyone a chance."

Cab service in the city of Boston has been restored.

Police recovered a bullet-riddled grey Honda CRV that was the vehicle hijacked by the suspects and was involved in a shootout with slain MIT police officer Sean Collier. The sequence of events is not clear.

Bloomberg News report bombing victim Jeff Bauman played a key role in identifying the suspects. His brother Chris says that when his brother woke up at the hospital under heavy medication following surgery he requested a paper and pen and wrote, "‘bag, saw the guy, looked right at me."

He later described to investigators a man he says dropped a bag at his feet that went off two minutes later.

Jeff Bauman lost both his legs below the knees and was in a photo showing him being pushed in a wheelchair by a bearded man.
