WEST VALLEY CITY, Utah -- Police say four people were wounded Saturday when someone opened fire on a rap group stopped in the parking lot of a Walmart in West Valley City.

West Valley City Police confirm four people were shot in the parking lot outside of Walmart, 3180 South 5600 West. Fox 13 News first heard report of the incident shortly after 8:30 p.m.

Police say a rap group traveling in an RV was stopped in the parking lot and three members of the rap group were standing outside the RV. Police say someone in a red car, possibly a Hyundai, started a conversation with the group, then as they drove away on 5600 West someone inside that red car fired multiple rounds at the RV.

The three members of the rap group were stuck by gunfire, along with a bystander.

The bystander is a 14-year-old girl, and police say she was hit in the hip area and is in stable condition.

A 36-year-old male was shot in the leg and is listed in stable condition.

A 22-year-old male was shot in the abdomen and is listed in stable condition.

A 23-year-old male was shot in the buttocks and is listed in stable condition.

Police say a fourth person inside the RV was not injured.

Police say the three adult male victims initially left the scene and were located in the parking lot of a nearby school.

Police are investigating the incident, including the possibility it is gang related.

Lt. Amy Maurer, West Valley City Police, said they feel fortunate there weren't more injuries after a shooting in such a public place.

"It's sad to have four victims, but in a parking lot this size and as busy as it is, to not have more victims is kind of astonishing," she said.
