The Daily Beast spoke with Mr Alissa’s brother, who called him “very anti-social” and paranoid.

“When he was having lunch with my sister in a restaurant, he said, ‘People are in the parking lot, they are looking for me,’” the brother, Ali Aliwi Alissa, 34, said. “She went out, and there was no one. We didn’t know what was going on in his head.”

The brother said the suspected shooter became more paranoid around 2014, prompting concern from his siblings.

“We kept a close eye on him when he was in high school. He would say, ‘Someone is chasing me, someone is investigating me.’ And we’re like, ‘Come on man. There’s nothing.’ ... He was just closing into himself,” the brother said.

He said his brother had previously been outgoing, but turned anti-social after he was subjected to bullying in high school.

CNN reported that the family emigrated to the US from Syria in 2002.

According to local news reports, the Alissa family operated a number of successful Middle Eastern food restaurants.

The Denver Post also spoke with several of the suspected shooter's former wrestling teammates, who said Mr Alissa was prone to outbursts and, at least on one occasion, was violent.

The Washington Post spoke to another classmate who described Mr Alissa as a very solitary individual, enough so that they tried to include him in activities.

“In high school, he didn’t really have a lot of friends, and that’s why [the other student] and I tried to reach out and make him welcome,” said the classmate, who spoke on the condition of anonymity. “He was alone and he was just kind of shy.”

Investigators who spoke with the suspected shooter said they were still collecting statements, but confirmed he has lived the majority of his life in the US.

Facebook confirmed it deleted a profile belonging to an “Ahmad Al Issa” who was born in 1999 in Syria, and was a wrestler at Arvada West High School.

A number of posts on the profile suggest he was interested in martial arts, wrestling and kickboxing. Mr Alissa apparently studied computer engineering at Metropolitan State University of Denver.

Mr Alissa is currently being held in the Boulder County Jail. Investigators believe he acted alone in the attack.

Following the shooting, police conducted a search of Mr Alissa’s home, where they found other weapons.

According to a police affidavit, just as officers arrived, they intercepted a woman leaving the house. The woman said she had recently married one of Mr Alissa’s relatives, and told detectives that she saw the suspected shooter playing with a “machine gun” inside the house two days prior.

The gun used in the attack, an AR-15-style pistol modified with an arm brace, was purchased six days before the attack.

Police have not yet identified a motive in the shooting.

“Regarding the suspect, at approximately 2:40 P.M. Monday, March 22, officers were dispatched to Kings Soopers. They arrived on the scene within minutes and immediately entered the store and engaged the suspect. There was an exchange of gunfire. The suspect was shot and a number of other officers were injured,” Boulder Police Chief Maris Herold said.

The police chief said her department was working with state and federal authorities to continue the investigation.

“We’re committed with state, local, and federal authorities for a thorough investigation and we’ll bring justice to each of these families,” she said.

The victims of the King Sooper mass shooting in Colorado have also been identified by police.

The 10 victims were identified in the early morning hours of Tuesday by the Boulder County Coroner’s office. The victims of the shooting have been identified as:

Denny Stong, 20; Nevin Stanasic, 23; Rikki Olds, 25; Tralona Bartkowiak, 49; Suzanne Fountain, 59; Teri Leiker, 51; Eric Talley, 51; Kevin Mahoney, 61; Lynn Murray, 62; Jody Waters, 65.

One of the victims, Boulder Police Department officer Eric Talley, was killed in the attack. He was the first officer on scene after the attack began.

Another victim was found in a car in the parking lot. The individual apparently was parked next to the shooter when he arrived.

Ms Herold said Mr Talley had seven children. “Our hearts go out to all the victims killed during this senseless act of violence,” Ms Herold said.
