On Monday, a senseless act of violence has left 10 people dead, including a veteran police officer, after a mass shooting incidence inside a Boulder, Colorado grocery store.

The police officer, identified as Eric Talley, 51, has served for the past eleven years.
Talley, who has been hailed as a hero, was first on the scene at King Soopers, where the shootings occurred.

“He was, by all accounts, one of the outstanding officers at the Boulder Police Department, and his life was cut far too short,” said the Boulder County district attorney, Michael Dougherty, reports the New York Times.

One man was arrested and is receiving medical treatment after being taken away in handcuffs. He was injured during the incident.

Family members of the nine other victims were still being notified, and no names have yet been released.

Law enforcement agencies from other states are helping Boulder police and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.

White House press secretary Jen Psaki sent a tweet that President Biden has been informed about the shooting and will receive updates if there are additional developments reports FoxNews.

FOX 31 Denver reported witnesses had heard sounds similar to fireworks and saw a man dressed in tactical gear, carrying an “AR-15 style weapon.”

KCNC-TV reported family members were inside the store, lined up to receive their CCP virus vaccine.

The Associated Press reported a witness describing how he had just left the store when he saw three people lying face down, two outside in the parking area and one in the doorway. He was unsure if they were still alive.

A posted youtube video showed a similar scene, with the sound of two gunshots at the start of the video clip.

One other person was observed being held against an outside wall by police before being led away without handcuffs.

Rep. Lauren Boebert (R-Colo.), a staunch supporter of the Second Amendment, said she was praying for “employees, first responders & others affected by the shooting in Boulder.”

Democrat Gov. Jared Polis said he is heartbroken over the shooting.

“My heart is breaking as we watch this unspeakable event unfold in our Boulder community,” he said. “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.”
