Ruslan Tsarni said his brother's family moved to the Boston area in 2003 and that he hasn't spoken to his brother since 2009. He said the suspects "put a shame" on his family and "the entire ethnicity."

"My family has nothing to do with that family," he said. "Of course we're ashamed. Yes, we're ashamed. These are children of my brother, who has little influence over them. Honestly, as much as I know, had little influence of them."

Ruslan Tsarni declined to say why he hasn't been in contact with the family, calling it a personal matter. "I just wanted my family to be away from them," he said.

Alvi Tsarni, who lives about a mile from Ruslan Tsarni, said the estrangement was related to a disagreement between the wives of his brothers. The issue was unrelated to the attack, he said.

"How I feel? I don't know how to say. I don't feel anything. I'm just tired of everything," he told reporters outside his home.

Asked if he had a message for the nephew who was then at large, he said, "He's not going to listen to me. What I can I tell him? Why do you think he is a separate family? They do not listen. They argue with us."

Neighbors described Alvi Tsarni as a kind man who regularly helped neighbors in the Montgomery Village townhouse community.

"He was friendly and really kept to himself," said next-door neighbor Nicole Cashaw, 30. "He was very straight and narrow. He did a lot of work for people around the neighborhood."

"I'm sure he's shocked, too. I feel bad for him," said neighbor Nadia Evans, 30. "It's unbelievable that something that happened so far away could be connected to us."
