A Mississippi man on a shooting rampage killed six people, including his ex-wife at three separate locations on Friday.

Tate County Sheriff Brad Lance said on Facebook that Richard Dale Crum, 52, was taken into custody and has been charged with first degree murder. More charges are expected, he said.

The sheriff told CNN the first 911 call came in at about 11 a.m. when the gunman pulled into the parking lot of convenience store in rural Arkabutla, about 45 miles south of Memphis. There, he allegedly shot and killed the driver of a car next to him, leaving another person in the car uninjured.

Crum went inside the store briefly, then came back out and drove his to ex-wife’s home, where he shot and killed her and physically struck her fiance.

Deputies caught up with him when they found a vehicle matching the suspect vehicle’s description in front of a home — which turned out to be Crum’s home, the sheriff said. Deputies spotted Crum trying to flee the scene and took him into custody.

They found two men shot dead on a road behind Crum’s house — one on the roadway and one in vehicle. Two more people, a man and a woman, were shot and killed at a house next door to Crum’s house, Lance said, and those two may be related to the suspect.

The sheriff said another person was wounded in the shootings but was treated and released by emergency crews.

Lance told CNN that deputies found several handguns and a shotgun in Crum’s vehicle.
