Sarah Moonshadow, forty-two, a customer and resident of Boulder, was in the store with her son, Nicholas, on Monday and recounted scenes of pandemonium as gunfire rang out.

"I said, 'Nicholas get down.' And Nicholas ducked. And we just started listening and there, just repetitive shots ... And I just said, 'Nicholas, run'," she told Reuters, as per The Guardian.

Another customer, Ryan Borowski, was inside the store when the shooting began.

He told CNN: "I saw terrified faces running towards me and that's when I turned and ran the other direction."

He said staff helped customers to exit from the back of the store but some people just froze on the spot: "We ran and I don't know why other people didn't and I am sorry that they froze and I just wish that this didn't happen – I wish I had an answer for why it did."

Alex Arellano, thirty-five, was working in the meat department at King Soopers when he heard gunshots and saw people running for the exit.

"I thought I was going to die," he told the New York Times, when he heard the shot getting closer, "I'm thinking of my parents, and I was freaking out."

He hid with 2 other men before escaping through a rear exit.

Yesterday, in the aftermath of the devastating incident, the perpetrator was identified...

Ahmad Al Aliwi Alissa was shot in the leg as he carried out the attack with a rifle, and was in the hospital on Tuesday morning, prior to being sent to jail.

Alissa who has been described by his family as "mentally ill," was born in Syria and moved to the U.S. with his parents when he was 3.

He lived around thirty miles from the grocery store he targeted on Monday.

He has been charged with ten counts of first-degree murder but his motive still remains unknown.

His Facebook posts over the last eighteen months prove to be deeply concerning.

His brother confirmed he was responsible for the shooting in an interview with The Daily Beast on Monday, saying he was "paranoid" and "very antisocial."

He continued, saying he believes his brother is mentally ill. He said from a young age, he was convinced people were "after him," especially in high school.

And now, harrowing police calls relive the moment it all began.

Dispatch audio, obtained by NBC's 9News, details the first report of a shooter, the chaos of an active shooting, and the moment officers were unable to locate Alissa.

When the first reports of a shooting came in at around 2:30 pm, a dispatcher could be heard on the police scanner, alerting officers: "It looks like we have an active shooter."

As officers arrived at the scene, one could be heard shouting "Shooter inside! He just shot at us twice."

Following that, another officer yelled: "Officer down inside the building."

While another revealed: "Multiple people down so far. One officer down. Unknown status. We can't get to him."

As per the Daily Mail, audio obtained the Colorado Sun reveals that around thirty minutes into the shooting, officers were instructed: "Due to body armor, head-shots only."

The suspects location was unknown for a short period.

As per Fox News, officers believed he could be setting up an ambush: "We have no known location of the shooter. We think he might be setting up an ambush."

Though officers were later able to obtain a visual of the suspect inside the store via a video feed.

Eventually, harrowing audio from a Denver SWAT team reveals they have "made contact" with the "possible suspect."
