According to two law enforcement sources, a witness, and a source familiar with the case, Andre Bing, 31, is the Walmart manager who murdered six people as well as himself on Tuesday night.

According to a source with knowledge of the situation, Bing worked as a nightly “team lead” at the Walmart in Chesapeake, Virginia.

Police told reporters on Wednesday morning that they had not yet notified the shooter’s next of kin and had not publicly identified the gunman. However, Chesapeake Police Chief Mark Solesky claimed that the shooter was a business employee.

The attack’s motivation is still a mystery.

Tuesday at 10:12 p.m., just over an hour before the Walmart Supercenter was scheduled to close, the deadly rampage began.

According to the police chief, four of the attack’s victims were still hospitalized as of Wednesday morning. According to Dr Michael Hooper, vice president and chief medical officer at Sentara Norfolk General Hospital, at least two patients were in severe condition.

According to Chesapeake Police spokesperson Leo Kosinski, investigators combed the business overnight into Wednesday in search of any victims or people who may have been hiding.

The shooting during Thanksgiving week is the latest mass shooting to occur in a location that is typically seen as safe, such as a school, hospital, or retail setting.
