BALTIMORE (AP) – A federal agency is offering a $20,000 reward for information in the fatal shooting of an off-duty D.C. police officer in Baltimore.

Forty-year-old Tony Anthony Mason Jr. was found with gunshot wounds early Saturday. He and a woman were sitting in a parked car when they were shot. Mason died at a hospital; the woman suffered a gunshot wound to her leg.

The Metropolitan Police Department in Washington said Mason, a sergeant, was a 17-year veteran of the force.

The Bureau of Alcohol, Tobacco, Firearms and Explosives offered the reward on Thursday.
