CHESTER COUNTY – PA is mourning the loss of a State Police trooper killed in the line of duty Sunday evening in Chester County. Officials say Cpl. Timothy O’Connor had stopped an erratic driver around 8:15 p.m. at the intersection of Compass and Michael Roads in West Caln Township. O’Connor called in the stop and that was the last authorities heard from him. As O’Connor approached the vehicle, the driver open fire, killing him. The driver, a 32-year-old Chester County man, then took his own life. When O’Connor did not respond to further calls, authorities responded to the scene and found the two deceased individuals. Gov. Josh Shapiro responded saying, “ Lori and I mourn with the Pennsylvania State Police family and with all of our law enforcement partners. I’ve directed flags across our Commonwealth to be lowered Monday in honor of Corporal O’Connor. May his memory be a blessing.” O’Connor leaves behind a wife and daughter.
