“I have no doubt that he was going back to finish what he started and we would probably have a dead victim today instead of one that’s alive," Bolin said during a press conference Friday.
The wounded woman was taken by helicopter to an Indianapolis hospital and was in stable condition, according to Gray.
At least eight officers fired shots as they tracked Mosley, whom Bolin said left a suicide note.
“He absolutely planned to die last night," Bolin said.
Gray said investigators did not yet know when Mosley acquired the handgun he used in the shooting or how many shots he fired.
Body camera video played during the news conference showed one officer holding an assault rifle in front of him and another officer in front of him moving through the aisles of the store until gunfire is heard from elsewhere in the store and an officer shouts: “Drop it! Drop it!” Moments later, a voice is heard saying, “He’s down, target is down.”
The shooting was not the first criminal incident involving Mosley at the store. He was fired from the store after being charged with four misdemeanor counts of battery on May 18, 2022, after he attacked four co-workers. A probable cause affidavit filed in the case states that Mosley told police he had issues with people at work and “lost control.”
The case was eventually referred to Vanderburgh County’s mental health court.
He had pleaded guilty to the battery charges and was complying with mental health treatment through the court, Vanderburgh County Prosecutor Diana Moers said. Mosely had in fact appeared for a progress hearing on Thursday afternoon, just hours before the shooting.
Moers said Mosely's conviction on misdemeanor battery charges “wouldn’t be one that exclude him from owning a handgun, necessarily.”
Walmart, the Bentonville, Arkansas-based retail giant, said in a statement that the “entire Walmart family is shocked by the senseless violence that occurred at our Evansville store, and our hearts are with our associate at this time.”
The company said in a separate statement that it does not discuss personnel matters involving current or former employees, but said that Mosley “has not worked for Walmart since May 2022."
Indiana has a “red flag” law, which legislators passed in 2005 and allows police or courts to seize guns from people who show warning signs of violence. However, after the May incident at the store, red flag court proceedings were not initiated against Mosley, according to Winston Lin, chief deputy prosecutor for the Vanderburgh County Prosecutor’s office, said Friday.
Indiana University law professor Jody Madeira, an expert on Indiana's “red flag” law, said prosecutors most likely would not have filed such an action in this case office unless there was a threat of gun violence in Mosley's past, and there was no indication there was.
She noted he had been complying with court-ordered mental health treatment.
Evansville, a city of around 116,000 residents along the Ohio River, is about 170 miles (275 kilometers) southwest of Indianapolis.
A Walmart manager in Chesapeake, Virginia, killed six people in November when he began shooting wildly inside a break room before a routine employee meeting, two days ahead of the Thanksgiving holiday. Six people were also wounded. The gunman shot and killed himself before officers arrived.
