WZTV, a local Fox affiliate based in Nashville reported that the alleged shooting occurred following a domestic dispute between Smith and the woman, who was not identified by police. The couple and the woman’s five children — who ranged in age from 1 to 13 years old — were all from Iowa and visiting family in the Nashville area.

The seven passengers were traveling in a Dodge minivan when, according to police, an argument between Smith and his girlfriend sparked a physical altercation. Smith reportedly grabbed the woman’s phone and threw it out the window of the van. He also allegedly tried to grab the steering wheel of the van.

WZTV reported that the woman was able to pull the vehicle over on a suburban road, at which point Smith allegedly opened fire on her, hitting her multiple times. She was able to escape the van to run for help, but while she ran, Smith then allegedly turned his gun on the children, firing several shots at them while inside the van.
