KNOXVILLE, Tenn. — A man fatally stabbed three people and wounded a fourth at a Tennessee travel center Tuesday morning before a deputy shot and killed him, authorities said.
The Knox County Sheriff's Office responded to a call at the Pilot Travel Center off Interstate 40 to find a person with stab wounds outside the store and a man armed with a knife in the parking lot, the Tennessee Bureau of Investigation said in a statement. Witnesses identified the man as the suspect and he refused deputies' demands to drop the weapon, the bureau said. As some point during the encounter, a deputy fired, striking and killing the suspect, the statement said.
Authorities found four stabbing victims. Three were pronounced dead at the scene and the fourth was taken to a hospital for treatment. The victims include Pilot employees, Tennessee Bureau of Investigation spokeswoman Leslie Earhart told news outlets.
Travel centers like Pilot offer gas, food, parking and other amenities to truckers and other travelers.
Investigators were still working determine a motive for the violence, Earhart said. The bureau did not release the names of any victims or the suspect.
Knox County Sheriff Tom Spangler said the deputy who fired the shot was not hurt.
The investigation remains active and ongoing.
"It's a very large scene — it involves outside and inside," said Earhart.
Pilot CEO Jimmy Haslam came to the center and could be seen conferring with Spangler and other authorities, the Knoxville News Sentinel reported.
