McCOY The Philadelphia Inquirer An off-duty Philadelphia police officer suspected of driving under the influence injured two state troopers and a tow-truck driver yesterday when his vehicle crashed into a state police car on a shoulder of I-95, authorities said. Officer Matthew Sharkey, 23, was detained on suspicion of DUI after the accident, which hurt Troopers Matthew Sheeran and Michael Sadowski, state police said. The agency is investigating the crash. Sheeran was in fair condition at Hahnemann University Hospital, according to a spokesman there. Sadowski was treated at Hahnemann for cuts and bruises and released. Sharkey also briefly received medical care there. The tow-truck driver was also treated at Hahnemann, but there was no word on his condition. The accident happened about 3:30 a.m., after the troopers had parked their cruiser behind an abandoned car on northbound I-95 near the Girard Avenue interchange, state police said. The tow-truck driver had pulled in front of the abandoned car and was underneath it, hooking it up, when Sharkey's car drove through warning flares and hit the back of the cruiser, authorities said. Sheeran was pinned between the cruiser and the abandoned car. Despite his cuts and bruises, the tow-truck driver crawled out from underneath and pulled the truck forward, freeing Sheeran. State police did not identify the tow-truck operator, saying only that he worked for the Philadelphia Parking Authority. Sharkey was tested for alcohol and drugs, but no results were immediately available. No charges had been filed, and the state police asked witnesses to call 215-560-6200. Sharkey joined the force in 2007 and has been assigned to the 17th Police District at 20th and Federal Streets in South Philadelphia.
