During the past two days, the prosecution presented evidence about the murder of MIT police officer Sean Collier and the kidnapping of Dun Meng, a Chinese businessman, and his Mercedes vehicle by the Tsarnaev brothers.
The Boston Globe reports,
Dr. Renee Robinson, a state medical examiner, told jurors that the 26-year-old Collier was shot three times in the head, including once between the eyes, and three times in the hand, and he would have died instantly. Robinson said the shots were fired at close range, at least one with the muzzle pressed against his skin, based on the pattern of the bullet’s entry wound.
Two people were captured on campus security video approaching Collier’s vehicle from behind after he pulled over and stopped. They are visible leaving the scene from the same direction that they approached. The apparent motive for the murder was to steal his gun, but they were unsuccessful because it was locked in his holster. Police discovered that the holster had been damaged in an apparent effort to remove the gun.
Dun Meng, the Chinese businessman, testified about his encounter and escape from the Tsarnaevs. Here’s the Globe again,
Sitting at the edge of his seat, he described how he took several turns, and pulled his car to the side of the road on Brighton Avenue to send a text message to a friend. Suddenly, a sedan pulled up behind him quickly. A man stepped out of the passenger side of the car, approached his passenger side window and tapped. He asked him to lower the window. Deng thought he was going to ask for directions, but the man instead reached inside and opened the door, stepping inside his car.
“He pulled the gun to me, to my head,” Meng told jurors, describing how he thought he was being robbed. The man pulled out his magazine, to show he had bullets.
“I’m serious, don’t be stupid,” the man told him.
Then he said, “Do you know the Boston Marathon explosions? I did it, and I just killed a police officer in Cambridge.”
Meng identified Tamerlan Tsarnaev as the man with the gun. Dzhokhar Tsarnaev was following behind them in a green Honda. He eventually parked the car and joined them sitting in the back seat behind Meng. Dzhokhar used Meng’s ATM card to withdraw $800. Meng escaped when they stopped at a Shell station for gas while Dzhokhar went inside to pay for the gas and Tamerlan was distracted fiddling with a GPS device.
Meng unbuckled his seatbelt with one hand and unlocked and opened the door with his other hand. He tumbled out onto the ground and took off in a crouching sprint across the street to a Mobil station where he called 911.
Police were able to find the Mercedes because it was equipped with a sophisticated GPS positioning system that located it precisely. The shootout ensued.
So far the evidence has shown Dzhokhar to be a willing participant and that is going to hurt his chance to beat the death penalty.
