Jurors in an Albany murder trial saw graphic video of the crime in court Tuesday.
Brian Beasley is accused of gunning down an Albany High School student, 19-year old Robert Purvis, at a Mock Road car wash in February 2011.
Prosecutors played surveillance video that shows Purvis walking up to a car as his girlfriend washes a car in the next bay.
Suddenly, Purvis falls backward after being shot at least twice in the chest.
Beasley sat quietly in court with his head down as the video was shown.
The shooter got out of his car, walked to Purvis's car, then came back to the body and took Purvis's car keys, and drove away in the teen's car.
Jurors then heard from Purvis's girlfriend, Shanna Moore, who is seen on the surveillance video finding his body.
