PENN TWP — Four people were hurt Thursday afternoon in two separate accidents on Route 8 less than a half mile and about an hour apart, police said. Medical helicopters flew both drivers in the second crash to a Pittsburgh hospital, said Middlesex Township police officer Randy Ruediger. Middlesex police, who have a mutual aid agreement with Penn Township police, investigated that crash about 2:35 p.m. at Route 8 and Renfrew Road. Police described both drivers’ injuries as moderate. The crash happened when a 2009 Pontiac Vibe driven by Frank Colosimo III, 42, of Penn Township pulled out from Renfrew Road and into the path of a 1999 Subaru Forrester. The Subaru, which was southbound on Route 8, struck the Pontiac, badly damaging the vehicle. Ruediger said the Subaru driver was taken to the hospital before policecould speak to her. Penn Township volunteer firefighters had to use a Hurst tool to force open the door of the Vibe to reach Colosimo, who was trapped in the vehicle. Ruediger said Colosimo told him he never saw the other vehicle when he pulled out. The officer said the crash remains under investigation and he has made no decision if charges would be filed. The crash occurred just after Penn Township police had cleared the scene at an earlier accident on Route 8 at McBride Station. In the first accident about 1:30 p.m., the driver of a van had pulled into McBride Station to turn around and crossed onto Route 8 into the path of a car traveling south, said Ruediger, who assisted Penn police. Both drivers were taken by ambulance to Butler Memorial Hospital with minor injuries. The accident is under investigation.
