Reward offered for information on slaying of D.C. cop in West Baltimore

The Bureau of Alcohol, Tobacco, Firearms and Explosives is offering a $20,000 reward for information on the slaying of an off-duty Washington, D.C. police officer who was killed in West Baltimore last weekend.

Tony Anthony Mason Jr., 40, was found suffering from gunshot wounds in the 2800 block of Elgin Ave. on Nov. 4, police said. He was taken to an area hospital, where he died of his injuries. Mason was a sergeant with the Metropolitan Police Department in Washington and was off duty when the shooting took place.

Police say Mason was sitting in a parked car when the shooting occurred. A 43-year-old woman who was with him was shot in the leg and treated at the hospital, police said.

Investigators believe an unknown suspect approached the parked car, began shooting, then fled.

The ATF is offering up to $20,000 for information leading to the arrest and conviction of the person responsible.

Anyone with information can call Baltimore homicide detectives at 410-396-2100, or (888) ATF-TIPS.
