Six people were killed and four more were hospitalized after a shooter opened fire inside a Walmart Supercenter in Virginia late on Tuesday. This was the second high-profile mass murder in a short period.

Police have confirmed that the attacker has also died from a gunshot wound that was likely self-inflicted.

In a press conference held early on Wednesday, Chesapeake Police Chief Mark Solesky stated that the shooter was a business employee but that his identity would not be released until his next of kin had been notified.

At the site, he was discovered dead.

Regarding whether the victims were customers, employees, or both, the police declined to comment. Police emphasized that they couldn’t say whether the shooter had been targeting anyone because the investigation could take days.

The number of customers inside the store at the time of the shooting, which occurred during busy pre-Thanksgiving shopping hours, is also unknown.
