Callie Weems was reveling in her new role as a mom in the months before a gunman in Arkansas fatally shot her at a grocery store.

Her daughter Ivy, now 10 months old, was a constant source of entertainment and wonder, Weems’ mother, Helen Browning, 53, said in a phone interview Sunday as she shared memories of her daughter.

Weems was among four people fatally wounded and another 11 injured — including the suspect — at the Mad Butcher store in Fordyce, Arkansas, on Friday, according to authorities. Just an hour before, Weems was marveling that her little girl had let her sleep in until 9 a.m. that morning.

“I bet you feel like a new mom,” Browning recalled texting back.

It was the last conversation they had before police say Travis Eugene Posey, 44, of New Edinburg, opened fire at the store, riddling cars with bullet holes as panicked bystanders ducked and scrambled for cover amid a barrage of gunfire. Weems, a nurse, died helping another gunshot victim, Arkansas State Police Director Mike Hagar said Sunday.

“Instead of fleeing the store, she stopped to render aid in one of the most selfless acts I’ve ever seen,” he said at a news conference.

In all, state police said 15 people were shot Friday, including 12 civilians, two law enforcement officers and Posey.

It was at least the third mass shooting at a U.S. grocery in the last three years. In 2022, a white supremacist killed 10 Black people at a Buffalo supermarket. That came a little more than a year after 10 people were fatally shot at supermarket in Boulder, Colorado.

Police said Sunday that Posey’s motive was still unclear, but he appeared to have no personal connection to any of the victims.

He carried a 12-gauge shotgun, a pistol and a bandolier with dozens of extra shotgun rounds, authorities said. He fired most, if not all, of the rounds using the shotgun, opening fire at people in the parking lot before entering the store and firing “indiscriminately” at customers and employees, Hagar said.

Fordyce police and Dallas County sheriff’s deputies arrived within minutes, and Posey exited the store and exchanged gunfire with them before they shot him and took him into custody.

For Browning, the tragedy was amplified by her connection to another victim, Roy Sturgis, 50, who was also shot and killed. She said Sturgis was part of her extended family, a logger and a loving father to his daughter.

“Roy was as country as cornbread,” she said. “He lived a simple life. He was a simple man.”

The other victims who died were identified as Shirley Taylor, 62, and Ellen Shrum, 81.

Taylor took care of her husband, who had diabetes, and crocheted, her daughter, Angela Atchley, told KTHV in Little Rock, Arkansas. “She was our family rock,” Atchley said.

Fordyce, a city of about 3,200 people located 65 miles south of Little Rock, was reeling from the shooting, City Council member Roderick Rogers said Sunday.
