A Walmart parking lot in suburban Nashville, Tennessee, descended into the Wild West Monday night, as a man fired several bullets toward a woman he knew – sending her screaming into the store for help – before getting into his truck and nearly running over an innocent bystander. 

Nashville police officers responded around 6 p.m. to a "shots fired" call at the Walmart on Gallatin Pike North in Madison, a suburban neighborhood in northeast Nashville – though learned upon arrival that no one had been struck by gunfire. Still, three people were taken to local hospitals. 

It started when a man and a woman got into an argument outside.

The unidentified man, who police tell WSMV possibly was having a mental health crisis, fired several rounds at the woman. Witnesses told WTVF that the woman ran into the store for help, causing a scare by frantically screaming that she had been shot. She, in fact, was not struck, police said. 

Nashville Fire Department crews also responded to the scene to reports about a potential gunshot victim needing treatment – yet the woman was not wounded, WKRN reported. 

The man reportedly got back into his vehicle, driving into and striking another man, a bystander, in the parking lot.

The bystander was transported to Skyline Medical Center to be treated for minor injuries.
