At least two people are dead after what the Knox County Sheriff's Office is investigating as a murder-suicide at the Weigel's on E. Gov John Sevier Highway.

Investigators said the shooting happened in the parking lot just before 6:00 p.m. Wednesday night.

The sheriff's office said 41-year-old Jason Nasca shot and killed 23-year-old Nicholas Strange following a verbal altercation between the two. Nasca then shot and killed himself.

A representative with the Knox County Sheriff's Office says Nasca had a carry permit.

Several witnesses told our crew on the scene that they saw a person about to back into another car and that another person saw the possible collision, then honked their horn to warn the driver.

Deputies said the two men did not know each other.

The Knox County Sheriff's Office Major Crimes Unit is investigating.
