Sean Lavell David Murphy was shot and killed in the late afternoon of February 25, 2010, while stopped at a traffic light in the Polish Hill neighborhood of Pittsburgh. He was 40 and driving a Cadillac Escalade at the intersection of Paulowna Street and Bigelow Boulevard when a man approached the vehicle and opened fire. After being struck, Murphy’s vehicle accelerated and hit the car ahead of it, producing a four-car pile-up. He was taken to UPMC Presbyterian and pronounced dead at 4:14 p.m.

Police described the shooter as a Black male in his early 20s, about 5 feet 8 inches tall, wearing dark clothing; witnesses said the man fled on foot down Paulowna toward Brereton Street and then left in a black car. At the time of his death Murphy was awaiting trial on drug-related charges and had a criminal history spanning the prior decade.

Did anyone in Polish Hill that afternoon see the shooter or the black car that left the scene?
