Boulder police made the comments on Twitter, responding to what they said were “comments from some in our community who questioned the response time of our officers.”
Police have said they are still trying to determine the reasons for the shooting.
According to the store owner, the suspect passed a background check when buying weapons
“We are absolutely amazed at what happened and our hearts are broken by the victims and the families left behind,” John Mark Eagleton, the owner of Eagles Nest Armory in Arvada, said in a statement.
The gun shop will continue to cooperate fully “with investigators, Eagleton said.
“Ensuring that all sales that occur in our store is legal, has always been and will continue to be the top priority for our business,” the statement said.
“With respect to the firearm in question, a thorough background check was conducted as required by Colorado law and approval of the sale was provided by the Colorado Bureau of Investigation.”
Nothing in the federal system would have prevented Alissa from passing a background check and buying a firearm, a law enforcement source had previously reported to CNN.
The suspect pleaded guilty to a felony count of third-degree assault in 2018 after attacking a high school classmate a year earlier, according to court documentation and a police report. He was sentenced to one year probation, 48 hours of community service and anger response treatment, court documents report.
Why that King Soopers? Why Boulder? Why Monday?
“I think the families of the victims and the community are desperate to know the reason,” he told reporters. “We want to know the reason. And that will be the focus of our efforts in the future. It remains to be seen whether or not we are able to determine that.”
Boulder Police Chief Maris Herold said, “Why this King Soopers? Why Boulder? Why Monday? Unfortunately, at this time, we don’t have those answers yet.”
Presiding Judge Thomas F. Mulvahill agreed to set the next hearing at “about 60 to 90 days.”
The suspect moved out of the county jail after the threats
A prison official told CNN that Alissa has been expelled from the county jail after officers became aware of other inmates’ “threats to him.”
He was transferred in the early hours of Wednesday, according to Jeff Goetz, head of the Boulder County Prison Division.
Alissa was never in direct contact with the inmates and was not injured, but other inmates questioned him and made threats, according to Goetz. These questions were addressed to other officers.
