A murder-suicide that occurred Wednesday night in a South Knox County convenience store parking lot resulted from an argument over a "parking or traffic incident," Knox County Sheriff's Office spokeswoman Hillary Martin said Thursday.

Jason Patrick Nasca, 41, shot Nicholas Allen Strange, 23, after an argument around 6 p.m. outside the Weigel's convenience store, 3104 W. Gov. John Sevier Highway, and then turned the gun on himself, according to a news release from the Sheriff's Office. Nasca had a carry permit, according to the KCSO.

The men didn't know each other, authorities said. Martin wouldn't give specifics on the traffic dispute or how it led to the shooting.
