Derrick Banks, 28, was shot in the head and killed in the early hours of Sunday, January 30, 2011, in Brewerytown, Philadelphia. The shooting happened in the 2900 block of West Turner Street, not far from his home, and followed an argument, though reports do not specify what the disagreement was about.

Banks’s death occurred during a weekend that saw seven homicides across the city.

Does anyone who lived in Brewerytown at the time or who knew Derrick have information that could shed light on what happened that night?
