Two people are dead and two others injured following a shootout at a Mississippi gun shop that appears to have erupted when a dispute over a $25 fee escalated, authorities say.

Pearl River County Deputy Coroner Albert H. Lee told the Sun Herald that Jason McLemore and Jacob McLemore died in the Saturday afternoon shooting at McLemore Gun Shop.

The Sun Herald reports that Jason McLemore owned the store where the shooting took place; 17-year-old Jacob was his son.

Another father-and-son pair — Audy McCool and 29-year-old Michael McCool — were hospitalized after the shooting, reports indicate.

Here’s what authorities believe happened, according to the Sun Herald: Audy and Michael McCool came to the gun shop to pick up a gun that was being repaired. Jason McLemore’s wife was working in the shop at the time.

“There was some contention about a $25 fee,” Chief Deputy Shane Tucker told the Sun Herald.

That’s when McLemore’s wife contacted her husband, who raced to the scene with his son. An argument broke out, and eventually, gunfire did, too.

The woman wasn’t hurt in the incident, and charges had not yet been filed by Monday afternoon, Tucker told The Post.

“It’s just putting the puzzle together, and we want to take our time and do it right,” he said.
