Anthony Patterson was 20 when he was found dead inside a parked car near 800 Unruh Street in the Lawndale neighborhood of Philadelphia on July 18, 2011. His death came during a summer marked by a string of shootings and other violent incidents in the city.

Police opened a homicide investigation but did not immediately release information about suspects or a motive. Investigators faced a lack of witnesses and few leads, and the case joined several unsolved killings in the area at that time. Authorities continued to appeal to the public for any information that could identify who was responsible.

If anyone knew Anthony, saw activity around 800 Unruh Street on or before July 18, 2011, or has information that might help, please come forward.
