NORTH HAVEN — A 21-year-old New York man was killed late Friday night, Oct. 16, when a wrong-way driver struck his car on Interstate 91 South near Exit 9 in North Haven, setting off a four-vehicle crash, according to Connecticut State Police.
Troopers from Troop I were called to I-91 South in the area of Exit 9 at about 11:43 p.m. for reports of a wrong-way driver, according to the state police accident information summary. Before they arrived, the vehicle had been involved in a multi-car head-on collision.
State police said a 2018 Honda Accord was traveling south in the left lane when a 2005 Chevrolet Silverado, heading north in the southbound lanes against traffic, hit it head-on. The Honda then went into the left-center lane, where it was struck by a 2020 Jeep Grand Cherokee, and then into the right lane and shoulder, where it was struck by a 2022 GMC Terrain, according to the preliminary investigation.
The Honda’s driver, Ryan O’Shea, 21, of Stony Point, New York, was pronounced dead at the scene, state police said. His next of kin have been notified.
The wrong-way driver, identified by state police as Guillermo Carmona-Lopez, 31, of Bridgeport, was taken to Yale New Haven Hospital with serious, life-threatening injuries. The Jeep’s driver and front-seat passenger were taken to Yale New Haven Hospital and the GMC’s driver to St. Raphael’s with minor injuries, according to state police.
The State Police Collision Analysis and Reconstruction Squad responded and is assisting with the investigation, which remains ongoing. No charges have been announced.
