WEST CALN TOWNSHIP, Pa. – A Pennsylvania State Police Corporal was shot and killed in the line of duty in Chester County.

County and state officials say Cpl. Timothy O’Connor was shot during a traffic stop in West Caln Township.

Police officials say O’Connor stopped the driver for erratic driving just after 8 p.m. at the intersection of Compass Road and Michael Road.

According to 6ABC, Police say that within seconds of approaching the stopped vehicle, the driver opened fire, killing O’Connor, before turning the gun on himself.

O’Connor is a 15-year veteran of the Pennsylvania State Police.

He leaves behind a wife and a daughter, 6ABC says.

Officials are not releasing the suspect’s name at this time, but say he is a 32-year-old man from Chester County.

The county District Attorney is assisting in the investigation and says they will be looking into the man’s background and possible motives. 

Gov. Josh Shapiro wrote about Cpl. O’Connor’s death on social media, saying, “Pennsylvania tragically lost one of our finest when State Police Corporal Tim O’Connor was killed in the line of duty. I was at Paoli Hospital this evening with Corporal O’Connor’s wife Casey and his parents Maureen and Tim. My heart breaks for Tim and Casey’s young daughter and their entire family…. May his memory be a blessing.”

Shapiro has ordered that flags be lowered in O’Connor’s honor.

Timothy’s mother, Maureen O’Connor, wrote about her son’s death on Facebook:

“Our lives are forever changed. My brave, fearless son gave his life tonight in the line of duty. Always the vigilant protector, until the end. I will always be proud of you Tim. Rest in peace my boy. Mom has it from here.”

Pennsylvania House Democratic Leaders issued a statement Monday on O’Connor’s death:

The Pennsylvania State Troopers Association released a statement Monday from President Stephen Polishan on O’Connor:

“Losing a Trooper is a tragedy for all members of the Pennsylvania State Police, past and present. It is a deep and profound loss because he is our brother. It reminds us how dangerous this job is and that something as simple as tomorrow is never guaranteed. Corporal Tim O’Connor lived his life with honor, bravery and integrity. We will never allow his memory to fade because heroes are eternal. His wife, Casey, and young daughter will forever be part of our family. Please join us in praying for Corporal O’Connor and his beautiful family.”

Fraternal Order of Police State Lodge President Joseph Regan issued a statement about the shooting:

“We are heartbroken by the tragic loss of Pennsylvania State Police Cpl. Tim O’Connor, who was performing one of the most routine and most dangerous duties in law enforcement when he made the ultimate sacrifice.

“Behind every badge is a person who swore an oath to serve and protect, knowing that each shift carries risks most people will never fully understand. Cpl. O’Connor answered that call with courage and dedication, and his sacrifice will never be forgotten.

“This tragedy is a stark reminder of the dangers law enforcement face protecting their communities. We ask the public to keep Cpl. O’Connor’s family, friends, and the men and women of the Pennsylvania State Police in their prayers.”
