Ten people were killed, including a veteran police officer, during a mass shooting yesterday inside a grocery store in Boulder, Colorado.

The officer was identified as 51-year-old Eric Talley, who served since 2010. He was the first officer at King Soopers, the crime scene, after the shooting occurred at about 2:30 p.m. His actions were called heroic. Talley was the father of seven and his youngest is seven years old.

The suspect, identified as 21-year-old Ahmad Al Aliwi Alissa, is a resident of Arvada, Colorado, and has lived most of his life in the United States. He now faces 10 counts of first-degree murder.

Identities of the other nine victims include:

Authorities said that they are working to compile evidence. Several state and county law enforcement agencies were assisting Boulder police as well as the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Witnesses said they heard pops that sounded similar to fireworks and saw a man brandishing an “AR-15 style weapon” and wearing what looked like tactical gear. Citizens were in line for the COVID-19 vaccine inside the store’s pharmacy at the time of the shooting.

Another witness stated he had just left the supermarket when he heard gunshots and saw three people lying face down, two in the parking lot and one near the doorway. He said he “couldn’t tell if they were breathing.”

Video showed one person on the floor inside the store and two more outside on the ground. What sounds like two gunshots are also heard at the beginning of the video.

Authorities could also be seen leading at least one other person out of the store and pressing him against the exterior wall of the building before walking away with him. He did not appear to be handcuffed.

Colorado Governor Jared Polis issued the following statement:

“My heart is breaking as we watch this unspeakable event unfold in our Boulder community. We are making every public safety resource available to assist the Boulder County Sheriff’s Department as they work to secure the store. I’m incredibly grateful to the brave men and women who have responded to the scene to help the victims of this senseless tragedy.”
