Red Springs, N.C. — Robeson County's sheriff said Thursday that a domestic dispute led to a shooting that killed two women and sent two men, including the suspected shooter, to a hospital Wednesday night.

Kathy Bullard, 59, was found dead inside a home at 12156 N.C. Highway 211 West in Red Springs and Donna Matteson, 55, was found dead outside the home around 6:30 p.m., Sheriff Ken Sealey said Thursday.

Sealey said Kendra Matteson, 24, called 911, reporting that her estranged husband, Joseph Matteson, 31, was outside the house with a handgun threatening to kill her.

Kendra Matteson had been staying with Kathy Bullard, Sealey said, and used to date Bullard's son, Mark Anthony Bullard.

When authorities arrived, Mark Bullard, 28, had also been shot in the hand, and Joseph Matteson was lying on the roadside with severe head injuries, Sealey said.

Investigators are still trying to determine what led to the shootings but say a neighbor attacked Joseph Matteson in an effort to end the rampage.

Both Mark Bullard and Joseph Matteson were listed in serious condition Thursday evening at UNC Hospitals in Chapel Hill.

Charges are pending.

Anthony Williams was working at a barber shop two doors down from Kathy Bullard's home when the attacks started.

"It's just so chaotic out there, and we don't know what's going on," he said. "People are hollering over there, screaming for help."

Williams said he walked outside and saw Kendra Matteson running with a gun that she apparently had grabbed from her husband while the neighbor was beating him.

"I see a lady standing at the edge of the road, and she's hollering, 'Help, help! I believe he shot everybody in the house,'" Williams said. "I said, 'Who?' She said, 'My husband.'"

Williams said Kendra Matteson was bleeding and feared for her children, ages 9 and 1. Neither of the children, however, was hurt.

"He's hollering for her to bring him his gun, and I'm standing right here and saying, 'Don't you bring him that gun,'" Williams said.
