The US Department of Justice on Monday announced that it has filed charges against Amazon over the shooting of a grocery store employee at the Ace Hardware store in suburban St. Louis, Missouri.

In a statement, the DOJ said that the incident that led to the murder of a store employee was “a violent, unprovoked attack.”

“The Department believes the conduct that led up to this horrific attack is not consistent with the standards expected of a large, publicly traded company,” the statement read.

“The conduct, including the use of an armed, threatening, and dangerous manner, is inconsistent with the business conduct of an enterprise that relies on customer loyalty to sustain its operations.”

The DOJ added that Amazon has made numerous representations to Congress, but the agency has not been able to determine “whether Amazon intends to cooperate with the investigation.”

In the statement, Amazon said it “fully cooperates” with the Justice Department.

“While we do not believe that there was any intent to kill, this case has led us to believe that Amazon is unfit to be a participant in the national dialogue around online safety,” the company wrote.

“As we have said before, we take this matter seriously and will work with the authorities to address any additional information that is requested.”

The statement was a clear rebuke to the company’s public response to the shooting.

“It’s unfortunate that a small handful of individuals decided to use the convenience of a remote control to commit this act of violence against innocent people, but it is our responsibility to hold ourselves and others accountable for our actions,” the CEO of Amazon, Jeff Bezos, said in a statement.

“Our thoughts and prayers are with the victims and their families.”

Amazon also added that the company “has been working closely with the St. Joseph County Prosecutor’s Office, and we will provide more information as it becomes available.”

The company did not immediately respond to a request for comment.
