McCOMB (AP) — A gunman shot two people to death Wednesday in the bank where his ex-wife worked, then took the ex-wife and killed her before committing suicide, authorities said.

The others killed were a customer and another employee of the Regions Bank branch in McComb, in southwestern Mississippi.

“It wasn’t a bank robbery. It was a domestic situation,” McComb Police Chief Billie Hughes said.

For a time police blocked off the area around the bank and told people to stay inside.

Hughes said an armed man walked inside the bank shortly after 11 a.m., fatally shot two people, took his ex-wife hostage and fled in a truck.

While police were at the bank, Hughes said, officers received a call that the ex-wife’s body had been found along U.S. Highway 51 near Fernwood, about four miles south of McComb. Hughes said he did not how the woman had died.

Police said Pike County deputies were then called to the scene of a one-vehicle accident in Magnolia, a few more miles south on the highway.

“(The ex-husband) apparently had shot himself while going down the street,” Hughes said.

Hughes said a handgun was found with the man’s body.

The gunman died at Southwest Mississippi Regional Medical Center in McComb, Pike County Coroner Percy Pittman said.

Hughes said all those involved were McComb residents, and that their names were being withheld pending notification of relatives.

Hughes said McComb police were being assisted by the Mississippi Bureau of Investigation, the Mississippi Highway Patrol, the Pike County Sheriff’s Department, the Magnolia Police Department and the state crime lab.

He said no other bank employees were harmed but were shaken by the shootings.
