BOSTON, Mass. (KOIN/AP) -- Federal officials are moving forward on legal proceedings against the only surviving suspect in Monday's Boston Marathon finish-line bombings.
The suspect, 19-year-old Dzhokhar Tsarnaev, has yet to be charged with any crime.
Dzhokhar (joh-KHAR') is still in serious condition at a Boston-area hospital. He is sedated with a tube down his throat.
He and his brother are accused of planting two explosives that killed three people and injured more than 180 at the marathon, before unleashing a barrage of gunfire and explosives on police in areas outside of Boston.
"Given what I have seen, it would be appropriate to use the death penalty," New York Senator Charles Schumer said. "And I hope it would apply."
More questions are being raised about the suspects and what the FBI knew before the bombing. In 2011, FBI agents interviewed the teen's older brother, Tamerlan. Tamerlan then made a trip to Russia in 2012, but his activities are unclear.
At FBI headquarters in Washington, spokesman Michael Kortan says the bureau's 2011 interview with Tamerlan was the only FBI contact with him. He's standing by the bureau's public statement from Friday in which the bureau described that interview. That statement said the FBI did not learn of the identities of the bombing suspects, Tamerlan and his brother, Dzhokhar, until Friday, the day Tamerlan was killed.
Tamerlan was killed during a getaway attempt early Friday.
Police say the 26-year-old also was run over by a car driven by his younger brother fleeing the gunfire. As of Sunday, Terrel Harris of the state Executive Office of Public Safety and Security said the medical examiner hasn't determined Tamerlan's cause of death.
A transit officer who was severely wounded in a Monday night shootout -- believed to be led by the bombing suspects -- remains in critical condition Sunday. Thirty-three-year-old officer Richard Donohue Jr. was shot early Friday morning in the hunt for the Boston bombers. Doctors say they're cautiously optimistic about his recovery.
As for Dzhokhar, he will be represented in court by public defenders, according to the Huffington Post. His parents in Russia now are insisting that the FBI continued to monitor his brother after the 2011 interview -- and both sons were set up.
