Days after news broke that a man had been charged in the 2016 death of her husband, a Wisconsin woman called for restrictions on the sale of hollow-point ammunition.

Stacy Blevins of Racine lost her husband, James Norris, last March when he was fatally shot while on the job. Earlier this month prosecutors linked prior felon Alex Adams, 28, to the robbery gone bad after the gun, a .38 caliber revolver found inside a Wal-Mart bag, was tied to him. According to court documents, the gun was stoked with hollow-points that Adams was shown on surveillance footage purchasing from the big box chain.

Blevins feels if it wasn’t for the type of cartridges used to shoot her husband three times, her life would be different and is asking Wal-Mart to either stop selling jacketed hollow-point ammo or perform background checks on those seeking to buy the rounds.

“If they hadn’t sold the bullets that man would be alive. This has got to stop. They shouldn’t sell hollow-points,” Norris’s mother-in-law, Sandra Stravropoulos, told The Journal Times.

Charles Crowson, a spokesman for Wal-Mart, defended the current practice, saying “The ammunition we carry is legal and in demand for self-defense and sport shooting among our customers. At this time, we don’t plan to remove the items.”

Adams, charged with first-degree intentional homicide and armed robbery, was arrested due to information developed through a Crimestoppers tip and was found to have searched for “murder charges in Wisconsin” prior to his arrest. He has a criminal record dating to 2006.
