Thomas Petersen, 32, was fatally shot during a carjacking in Philadelphia on January 24, 2017. Two Philadelphia police officers transported Petersen to Temple University Hospital, where he later died.

The shooting prompted a federal investigation by the Bureau of Alcohol, Tobacco, Firearms, and Explosives. A grand jury returned an indictment charging carjacking, use of a firearm in furtherance of a crime of violence, and murder in the course of using a firearm; Khalif Tuggle later pled guilty to those counts and received a 55-year prison sentence.

Anyone with memories of Petersen or information about the case is invited to share what they know.
