Investigators say just before 7 a.m. Tuesday, the Knox County Sheriff’s Office received a report of an incident at the Pilot Travel Center along Strawberry Plains Pike. Officers found one person with stab wounds outside the store.

A man, armed with a knife and identified by witnesses as the suspect, was also observed in the parking lot. Officers confronted the individual, who refused to drop the weapon. At some point during the encounter, one of the officers fired shots, striking the man. He was pronounced dead at the scene.

Three of the four who were stabbed were pronounced dead at the scene with the fourth victim rushed to a local hospital.

The Tennessee Bureau of Investigation is leading the investigation along with forensic scientists, who are working to gather any and all relevant interviews and evidence.
