A man whose car was stolen by the Boston Marathon bombers just days after the attack took place appeared in court on Thursday to describe the moment he was held at gunpoint by Tamerlan Tsarnaev.

Dun Meng said he pulled his Mercedes over to use his phone on April 18, 2013, when a man approached the window and pointed a gun at him. After a brief exchange, the man (later identified as 26-year-old Tamerlan) told him that he was responsible for the Boston Marathon bombing and ordered Meng to cooperate. 
"He pulled the magazine out of the gun to show me there's bullets in the gun. He told me, 'You know, I'm serious, so don't be stupid," said Meng, according to Reuters. 

Meng then rode around in the car with the two brothers, who told him they were bound for New York. Miraculously, he escaped unharmed while Tamerlan and Dzhokhar Tsarnaev were distracted during a stop at a gas station. 

He said the decision to try to flee was the "most difficult" one of his life. Though Tamerlan had told him he would not be killed, he recalled: "I was struggling, should I trust him about that? Or should I take this chance by myself and run away?" 

21-year-old Dzhokhar, the only living suspect in the 2013 bombing that killed three and left more than 260 others injured, could face the death penalty if found guilty.
