Thomas Ehret, 35, a Connecticut State Trooper, injured after his cruiser is struck by a tractor-trailer on I-95 near Stamford, Connecticut

A state trooper is recovering from injuries sustained when his cruiser was struck by a tractor-trailer on Interstate 95 in Stamford around midnight Tuesday. Police said Trooper Thomas Ehret, 35, had pulled over a car on I-95 southbound and was parked on the right shoulder near exit 8 when a tractor-trailer driving in the opposite direction drifted onto the shoulder and sideswiped the cruiser. The truck, driven by 44-year-old John Sgro, of Columbus, N.J., stopped briefly, then sped back up and fled the scene, police said. Stamford police stopped Sgro on I-95 northbound between exits 9 and 10. He was arrested and charged with evading responsibility, failure to maintain a lane and failure to move over when approaching a stationary emergency vehicle. Ehret was taken to the hospital for treatment of shoulder, neck and back injuries. Police said Sgro was not injured. Sgro was released after posting $2,500 bond and is due back in court April 8.
