WASHINGTON -- Despite reports that Tamerlan Tsarnaev harbored resentment over the U.S. denying his citizenship application, the application was still pending at the time of the Boston Marathon bombings, a law enforcement source said Sunday.
Tamerlan, 26, filed an application for citizenship six months ago and immigration officials had not yet made a decision on his case at the time of the Boston Marathon bombings, the source said.
Immigration officials were aware of a domestic violence charge on his record and also knew that the FBI had questioned him, the source said, but it's unclear what Tamerlan was told about his prospects for citizenship.
Days after the Boston Marathon bombings that killed three and injured more than 170, investigators are still trying to understand the motives of of the two prime suspects, Tamerlan and his younger brother, Dzhokhar Tsarnaev, 19. Authorities have begun to delve into the details of how the brothers came to be in the United States.
