McCOMB, Miss. (AP) — A man fatally shot two people Wednesday in the bank where his ex-wife worked, then fled with the woman and killed her before committing suicide, authorities said.

The others killed were a customer and an 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.

Robert Lanham walked inside the bank shortly after 11 a.m., opened fire, took his ex-wife hostage and fled in a truck, authorities said.

Whipple said investigators planned to present their report Wednesday to the county attorney, who will determine whether any charges should be filed against the woman's 36-year-old boyfriend.
