The man fatally shot while he worked at a Port Richmond Jiffy Lube on Wednesday afternoon was 40-year-old Samuel Rivera, of Olney.

Police said Rivera was driving a customer's car into the service bay when he argued with another man who then pulled out a gun and shot him in the face and the chest, fatally wounding him.

Cops have not yet identified a suspect in Rivera's murder. It's unclear what sparked the argument that led to his killing.
