The Knox County Sheriff's office has identified the two men who died in a murder-suicide that appears to have been prompted by an argument between strangers.

Deputies responded to the Weigel's at 3104 West Governor John Sevier Highway in South Knox County Wednesday around 6 p.m.

Investigators said that Jason Patrick Nasca, 41, of Knoxville shot and killed 23–year-old Nicholas Alexander Strange of Knoxville after a "verbal altercation" over a parking or traffic matter in the store parking lot. Nasca then shot and killed himself.

According to information from witnesses, KCSO said the two men did not know each other. Nasca did have a gun carry permit.

The KCSO Major Crimes Unit is investigating the incident.
