Carl Wideman, 26, was fatally shot outdoors in Philadelphia on November 11, 2013. The slaying came during a year marked by unusually high levels of gun violence in the city. Authorities have not identified any suspects and no arrests have been announced, leaving the case unsolved.

Police describe the motive as unknown; they note that many homicides that year resulted from arguments or altercations that escalated, but no official motive has been established for Wideman’s death. His family continues to live with the loss and the absence of answers.
