FROM EARLIER: Arkansas State Police say a sheriff's deputy was fatally shot and two other people were found dead in rural Arkansas on Thursday. Police say authorities are negotiating with a suspect who is holed up in a home.
State police spokesman Bill Sadler says Yell County Sheriff's Office Lt. Kevin C. Mainhart was en route to a disturbance call Thursday morning when he pulled over a vehicle. Sadler says Mainhart was fatally shot during the traffic stop.
Sadler says once officers arrived at the location of the initial disturbance call, they found two more people dead.
Sadler says authorities believe the traffic stop and the disturbance call are connected. He says the suspected shooter is now in a home in rural Arkansas and that officers are trying to coax him into surrendering.
A state police statement says Mainhart had worked as an officer in Yell County for five years and had previously worked 20 years with the West Memphis Police Department.
