In this intense interview with CBS Boston’s Peter Wilson, the bombing suspects’ uncle Ruslan Tsarni takes a far different tone than their father, who is Tsarni’s older brother.

During the course of the interview, Wilson informs Tsarni that one of his nephews, Tamerlan Tsarnaev, has been killed. Tsarni, clearly distraught, is nonetheless very clear about his feelings about his nephews-turned-suspects, saying Tamerlan, “absolutely deserved his.”

“Oh, I just wish they never existed. I’m wordless. I am wordless. I am wordless. Shocked,” he said. “I’ve just been watching it. I’ve been reading it. People who did that they do not to deserve even existing on this earth. They do not deserve to exist on this earth. That’s what I think.”

Tsarni, who lives in Maryland, said he hasn’t had much contact with his nephews for many years, and did not recognize them in pictures released by the FBI. As he’s giving the interview, his wife seems to bring him a clearer picture of the Tsarnaevs, and he confirms their identity. He said the young men came to the United States around 2000 or 2001, as young children.

In his last conversation with Tamerlan, around 2009, Tsarni said, “He started telling me about that he’s in Islam. I tell him, ‘Islam’s always been there. You just do your business. Work , go to school be useful, know why you came to America.’ And, I just said, and I’m sorry for my word… I said, ‘You prick.'”

Tsarni also called Tamerlan a “loser,” who had not finished school and gone to college as his younger brother had.

He said his nephews’ actions are “not comprehendible in our family,” saying he’d followed news of the bombings with everyone else and, “I was saying ‘these are barbarians, whoever they are.'”

“For people, listen, what can I say? Sympathy, condolences. That I’m with them! And, if some of them are ready to send their curses on me, I’m ready to accept it because I’m associated with these bastards (by blood). What else can I say? What else normal person can say?”

The suspects’ uncle said he didn’t know why they’d perpetrate such acts.

“They’ve been refugees in the is country. They’ve been refugees.” he said. “They got their start as refugees, refugees from war.”

Update: I corrected the curses quote, which I slightly misheard in transcribing.

Update: Alina Tsarnaev, who lives in New Jersey.

A woman who identified the Boston Marathon bombing suspects as her brothers can’t understand what happened this week in Massachusetts – any of it. “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.”

Law enforcement is on the scene at her New Jersey apartment:

A woman who lives with her husband and at least one child in an apartment building in West New York, New Jersey says she is the sister of the Boston bombing suspects. On Friday, the FBI Joint Terrorism Task Force, NYPD and local law enforcement swarmed the building on Buchanan Place in Hudson County and directly across the Hudson River from New York City. At least a dozen law enforcement officials made their way into the building. WNYC identified the woman as Alina Tsarnaeva and say she was cooperating with the FBI. Earlier in the morning she spoke to NorthJersey.com from the door of the second floor apartment but refused to give her name. She said she was shocked by the bombings and surprised her brothers could have been involved. She called them “loving” but said she had not spoken to the brothers in years.

WBZ radio in Boston reports that she “has not been in frequent touch with her brothers,” and is “sorry for all the people who are hurt.” Her residence was described as “cordoned off.”
