Walmart on Wednesday identified the store manager who police say opened fire at a store in Chesapeake, Virginia, killing six people and wounding at least six more.

The gunman, identified by the company as Andre Bing, died of a self-inflicted gunshot wound, Chesapeake Police Chief Mark Solesky said. A handgun was recovered at the scene.

Solesky said the first 911 call came in at Tuesday at 10:12 p.m. local time, and the first officers arrived two minutes later. There was no clear motive for the shooting, authorities said.

Walmart will “continue to work with local law enforcement as they continue their investigation,” said Robert Arrieta, a spokesperson for the company.

The shooting comes amid a wave of deadly gun violence in the U.S. and was the second major shooting in a little more than a week in Virginia. It was also the second high-profile mass shooting across the U.S. in less than a week span after Club Q, a gay nightclub in Colorado Springs, was attacked by a gunman.

Who was the gunman in the Chesapeake, Virginia Walmart shooting?

Walmart said Andre Bing, 31, was a “team leader” who had worked for the company since 2010. Bing was an overnight team lead, the news station WTVR in Richmond reported. A search of local and state court records did not bring up any previous criminal charges against Bing. USA TODAY could not locate any social media pages for him, either.
