Three people are dead after a shooting outside at a Walmart in Duncan, Oklahoma Monday morning, police confirm.
The shooting took place at about 10 a.m. at a Walmart along Highway 81 north of downtown Duncan.
Duncan Police Chief Danny Ford said two men and a woman were fatally shot outside of the store -- two were killed in a vehicle and the third in the parking lot.
KFOR-TV in Oklahoma City reported a man and woman were inside the store prior to the shooting and that the woman may have been an employee at the store. After they exited the store, a man walked up to the car they were in and fired at least nine shots before killing himself.
Investigators believe the three people knew each other, according to KFOR's report.
