Karl Kevin Sullivan II was taken into custody in Virginia late on September 10, 2026, following a standoff with authorities, bringing an 11-month manhunt to a close in the shooting death of 20-year-old Julian Lassic. The arrest closes out one of Washington, Pennsylvania's most closely watched unsolved cases, though police say the full details of what happens next will stay under wraps for now.
The City of Washington Police Department announced the arrest, saying it followed an agency-wide effort involving the department's patrol officers and investigators, according to WPXI. Police also confirmed the arrest location and standoff circumstances in a statement posted to the City of Washington Police Department's Facebook page. Lassic, who lived in Canonsburg and graduated from Washington High School in 2024, was shot in the 100 block of North Main Street and died at the hospital, per the same report.
A Bakery Alley Shooting That Shook Downtown
The fatal shooting happened at approximately 2:52 a.m. on October 11, 2025, in an alley outside Joe's Bakery on North Main Street, where a second victim was also shot and hospitalized in critical condition, according to CBS News. Lassic was rushed to UPMC Washington Hospital, where he was pronounced dead at 3:40 a.m., the station's report notes. The killing marked the second recorded homicide in the City of Washington that year, per the same account.
Four days later, on October 15, 2025, Washington police and SWAT officers executed a search warrant at a North Main Street building leased by the Sin City Deciples Motorcycle Club to recover surveillance video connected to the crime, CBS News reported. The raid illustrated how aggressively investigators pursued digital evidence in the early days of the case, even as the shooter remained unidentified for months afterward.
Mayor's Plea Against Street Silence
In the days after the shooting, Washington Mayor JoJo Burgess publicly called for community cooperation, condemning what he described as a “code of the streets” that discouraged witnesses from speaking up, and warning against rumors that had sparked threats of vigilantism, according to WPXI. The plea underscored the tension in a small city where fear of retaliation had apparently kept people quiet even as a homicide investigation stalled.
That tension over downtown safety only deepened weeks later. On November 27, 2025, less than seven weeks after Lassic was killed, another shooting occurred on the same 100 block of North Main Street, this time outside the Community Club, according to WJPA. The back-to-back violence on one commercial block fed broader public safety concerns in the downtown corridor.
A Suspect With a Prior Record
Sullivan was not unknown to law enforcement before Lassic's death. In May 2017, he was charged in Fayette County Magisterial Court with prohibited firearm possession, carrying a firearm without a license, child endangerment, drug possession with intent to deliver, and fleeing police, according to the Herald-Standard. That earlier case, filed nearly a decade before Lassic's killing, involved some of the same themes that would define the manhunt that followed: firearms and evading police.
What Comes Next
The City of Washington Police Department said it would not release additional details regarding a motive or evidence because formal criminal proceedings against Sullivan remain pending, a standard practice meant to protect the integrity of the case as it moves toward court. That means key questions — including what led to the shooting, the current condition of the second victim wounded outside Joe's Bakery, and the specific charges Sullivan will ultimately face — remain unanswered for now.
For a city that spent nearly a year watching an unsolved killing cast a shadow over its downtown streets, the arrest offers a measure of resolution, even as the courts have yet to weigh in. Washington police have not indicated when Sullivan is expected to be extradited or formally arraigned in connection with Lassic's death.
