Colorado attorney general says he's "deeply saddened" and "angered" by today's shooting From CNN's Dave Alsup
Colorado Attorney General Phil Weiser said in a statement that he's angered by Monday's shooting at the King Soopers supermarket in Boulder.
"I'm deeply saddened and angered with the news of another tragic shooting in Colorado," he said. "I'm thinking of all our fellow Coloradans in Boulder who were affected by the unspeakable violence that occurred at King Soopers on Table Mesa."
Weiser continued: "As we learn more about the incident, I'm thankful for the brave law enforcement officials and first responders who are assisting victims, securing the scene, and putting themselves in harm's way. Our office is standing ready and is committed to helping in any way that is useful."
Police say "multiple people" were killed during a shooting at King Soopers supermarket, including one Boulder police officer.
They provided information at a news conference just a few minutes ago, but they said the investigation is just starting.
Here is what we don't know:
Boulder Police Department Commander Kerry Yamaguchi said there is one suspect in custody, but they are still investigating if they were the only shooter. Officials say the suspect is being treated for their injuries.
Yamaguchi said they also don't have a motive yet. He said it will be part of the investigation to determine if there was any relationship between the gunman and the people in the store, adding he does not know if the shooter had any connection to any of the employees. Officials said they do not know what type of weapon was used or if the suspect was wearing military gear.
Earlier today, CNN affiliate KMGH's helicopter recorded a shirtless man being taken from the supermarket. The man had what appeared to be blood on his arm and right leg and his hands appeared to be cuffed behind him as two officers escorted him away into an ambulance. Yamaguchi said he cannot confirm who this person is.
The police commander said "multiple people" were killed in the shooting, including one Boulder police officer. Yamaguchi said police are still determining how many people died.
Michael Dougherty, the district attorney for Boulder County, added victims' families were still being notified.
Yamaguchi said they do not know how many people were inside the store during the shooting. He said this will be another part of the ongoing investigation.
Yamaguchi said the suspect has not been charged yet and there are no scheduled court hearings right now. Officials said the investigation is in the very early stages and there is still a lot of work to do.
Dougherty vowed to get justice for those involved.
