A carjack victim who escaped the Tsarnaev brothers was in court on Thursday to recollect his chilling run-in with the Boston Marathon bombers three days after the 2013 attacks.

Dun Meng, who moved from China to the U.S. in 2009 to attend Boston’s Northeastern University, testified in bomber Dzhokhar Tsarnaev’s trial that he had left work in Cambridge on the night of April 18, 2013, when he was carjacked by the Tsarnaev brother, who was later killed, according to WHDH.

A car quickly pulled up behind Meng and a man got out and knocked on his passenger-side window before forcing open the door, jumping in the passenger seat and flashing his loaded firearm at the driver.

CNN reported that after demanding money from Meng he asked if he knew who committed the Boston Marathon bombing. Meng acknowledged that he had heard about the tragedy, but did not know who did it, to which the man later identified as Tamerlan Tsarnaev said: “I did it, and I just killed a policeman in Cambridge.”

Tamerlan Tsarnaev is one of two brothers who had detonated two bombs near the finish line of the marathon, killing three people and injuring more than 260, in 2013. Prosecutors say Dzhokhar and Tamerlan Tsarnaev had earlier killed Massachusetts Institute of Technology Police Officer Sean Collier because they wanted to retrieve his gun although they were not successful in doing so.

After driving around for about 30 minutes, Tamerlan told him to pull over on a street in Watertown, Meng said. A sedan pulled up behind them before Tamerlan helped the driver load items from the sedan into Meng’s car.

While on the witness stand, Meng identified the second man as admitted Boston Marathon bomber Dzhokhar Tsarnaev. “The gentleman over there,” he said as he pointed to Tsarnaev. Meng also said Dzhokhar did not speak to him during the carjacking.

Meng said he decided to make his escape after Tamerlan pulled into a gas station and Dzhokhar went inside to pay. Recalling what he cites as the most difficult decision he has ever made, Meng slowly prepared himself to exit the car and bolted across the street to a different gas station.

The jury saw dramatic surveillance video of Meng running inside the station, holding the door shut and begging the clerk to call 911. In the video, he crouches to conceal his body before crawling into a storage room.

Tamerlan was killed after being run over by a car operated by his brother, shot by police bullets and enduring blunt trauma on April 19. Dzhokhar was captured hiding inside a boat that evening.
