Off-duty officer fires at stolen car - his mom's Trying to steal a car from the home of a police officer is not advisable. But if anything is even less wise, it is trying to steal a vehicle from the home of the officer's mother. Something like the second scenario unfolded Monday morning in Prince George's County, and it touched off a series of violent events. There was a car chase, and a confrontation on the street. That was followed by an effort to drive the vehicle at the officer, and finally, by gunfire. It all started about 6:45 a.m. at the home of a woman in the 4300 block of 23rd Place in the Temple Hills area, county police said. They said the woman's son, a member of the U.S. Park Police, was off duty and at her house when he saw her car being driven away. The officer got into his own personal car and drove after his mother's Corolla. About three blocks from the house, at Lynn and Olson Streets, the officer managed to confront the car thief. The officer, who was not named immediately, got out of his car and confronted the suspect, police said. But the thief revved up the Corolla, and drove towards the officer. The officer opened fire, discharging several rounds at the car, police said. Authorities are not sure whether anyone was struck by the gunfire. The officer was unhurt and the Corolla was abandoned in nearby Hillcrest Heights. On Monday evening, police were still looking for the thief.
