With one of the two Boston bombing suspects killed in a shootout and the other the subject of a massive manhunt, PEOPLE spoke with their shocked father, Anzort Tsarnaev, and their sister, Alina Tsarnaeva, on Friday morning.
"They never could have done this. Never, ever, ever!" Tsarnev told PEOPLE via phone from Russia. In a conversation filled with screaming and yelling, he was clearly in a state of disbelief and horrified by the events he watched unfold on TV.
"I feel terrible! Why they kill my son? Something wrong! My sons never do bombing," he insisted. "They hated guns – how they do bombs?"
"I am hurt for all the people who lost someone," Alina told PEOPLE from her home in New Jersey. "I lost a relative, my brother. I love my brothers, this is shocking. I don't know what got into them."
Tamerlan Tsarnaev, 26, was killed overnight, while Dzhokhar Tsarnaev, 19, remains at large, believed to be in the Boston area.
"My sons liked everybody. They very good kids," said Anzort Tsarnaev. "They never do bad things to anybody. I talked to my sons yesterday, both of them. We talked about the bombing. I was worried about them, they said they were okay."
The Tsarnaev brothers lived in the United States for several years, and Dzhokar was known as a popular, well-adjusted student in Cambridge, according to numerous reports. Their father, hysterical over the events in Boston, continued to convey his shock to PEOPLE.
"I am very depressed," he said. "How am I going to live? Never I think in my mind this happen. My sons hate people who do bombs, they hate terrorists. Why they kill my son? And where is my other son? They have time to catch my other son, not kill."
He adds that his sons were "never interested in politics" – they had "big dreams" to go into business – and that they are "Muslim, but not radical Muslim."
Their sister Alina, who spoke from behind the door at her home, added that she hasn't seen her brothers for a long time and, too, is in disbelief over the news.
"They were smart boys," she says. "I am just so hurt."
