‘Tragic’ and ‘profound’: Authorities mourn the loss of Cpl. Timothy O’Connor, state trooper killed in Chester County traffic stop

An air of unease swept over Chester County dispatchers Sunday night when reports came in of a shooting along a wooded stretch off Compass Road in West Caln Township — but no word from the state trooper on scene.

Corporal Timothy O’Connor had pulled over a car near a dead-end residential street, which leads to a cluster of low-slung mobile homes and ranch-style houses. Minutes later, responding officers arrived to find O’Connor’s cruiser and the suspect’s vehicle, according to scanner audio.

“Trooper and a suspect down!” one officer radioed.

O’Connor was rushed to Paoli Hospital, where he was pronounced dead. The driver, who police identified on Monday as Jesse Nathan Elks, fatally shot himself at the scene.

O’Connor, a 40-year-old Pennsylvania State Police officer, served on the force for nearly 16 years until the fatal traffic stop.

Within law enforcement across the state, O’Connor’s death reverberated deeply. He was the 105th member of the state police force to die in the line of duty, a loss his department described on Monday as “tragic” and “profound.” The Pennsylvania State Troopers Association called O’Connor a trooper who lived with “honor, bravery and integrity.”

O’Connor signed up with the Pennsylvania State Police in 2010, and served in both patrol and criminal investigations. He was most recently assigned in Troop J, Embreeville Station.

He was promoted to corporal in 2022, according to state police. The promotion elevated him into a leadership role within the department’s ranks — one of 63 troopers statewide who advanced to corporal and were recognized during a 2023 ceremony at the Scottish Rite Cathedral in Harrisburg.

O’Connor is survived by his wife, Casey, and their young daughter. Attempts to reach his family by phone on Monday were unsuccessful.

The officer’s mother, Maureen O’Connor, made a memorial post on social media early Sunday morning, honoring her son.

“Our lives are forever changed,” she wrote. “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. 💙”

O’Connor pulled Elks over shortly before 8:30 p.m. Sunday, after reports that Elks had been driving erratically near Compass Road and Michael Road, according to investigators. After radioing in the stop — the last his colleagues would hear from him — O’Connor approached the driver’s side door. Authorities say Elks opened fire, fatally wounding O’Connor, before turning the gun on himself moments later.

A solemn procession later carried O’Connor’s body from Paoli Hospital to the coroner’s office in West Chester for an autopsy.

In the hours after the shooting, Gov. Josh Shapiro ordered flags across Pennsylvania lowered to half-staff in O’Connor’s honor, calling the trooper “a hero” who died protecting others.

At a news conference Sunday, Shapiro hinted that the shooter’s motive may not be clear for some time.

“There are many questions, many of which will go unanswered,” Shapiro said. “But the one thing we absolutely know for certain is that [O’Connor] … died protecting others.”

Much remains unclear about the motive behind the killing on Sunday night.

Public records and social media posts left behind by Elks offer a loose portrait of a recently separated man who had moved into a mobile home park in Honey Brook, a quarter-mile from where the shooting took place.

A Facebook account under Elks’ name often posted pictures of himself with a Chester County woman and a young child.

One family photo posted in 2020 included a banner that read “ACAB,” an anti-police acronym for “all cops are bastards.”

Elks’ last Facebook posts date to three years ago, in 2022. Attempts to reach members of Elks’ family were unsuccessful on Monday.

Public records show that Elks shared a home with the woman until about that time. Elks later purchased a 1988 Skyline mobile home in the Hideaway Mobile Home Park, records show.

Police said the investigation is ongoing, and have not released any information about a suspected motive at this time.

Messages honoring O’Connor spread quickly Monday. In a Facebook post, Pennsylvania Attorney General Dave Sunday called the trooper’s killing “a tragic reminder that no traffic stop is ever routine,” adding that officers confront unknown dangers every day in the line of duty.

Pennsylvania House Democratic leaders echoed that sentiment in a statement thanking law enforcement officers who “put their lives at risk every day to keep us safe.”

Tributes also came from fellow officers. Police departments across Pennsylvania posted messages honoring O’Connor and expressing support for his family and the Pennsylvania State Police, describing the shooting as a devastating loss felt across the law enforcement community.

“May Corporal O’Connor’s memory be a beacon of inspiration to us all, and may his family find comfort in the knowledge that his sacrifice will never be forgotten,” the Upper Merion Township Police Department wrote.
