Manuel Sanchez was a 25-year-old resident of Philadelphia who was killed on December 20, 2012, one of six people killed during a particularly violent weekend in the city. His death was part of a surge in gun violence that December, when Philadelphia recorded 46 homicides, and contributed to an overall 2012 total that reached 306 homicides by year’s earlier tally and 499 by year end as the city struggled with escalating violence.

If anyone knew Manuel, witnessed the December 20 incident, or has information that could help, please come forward.
