Family of the suspected Colorado mass shooter speaks out; he's 'deeply disturbed,' anti-social'

A shooting at a Boulder, Colorado supermarket Monday left 10 people dead and the suspect in police custody, charged with 10-counts of first degree murder.

Tuesday police identified the shooter as 21-year-old Ahmad Al Aliwi Alissa, from Arvada, Colorado.

Alissa’s 34-year-old brother Ali Aliwi Alissa tells Daily Beast that his brother was “deeply disturbed,” and “very anti-social.”

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

A woman, identified as an older sister of Al Alissa says that no one in the family would have ever believed he was capable of such a horrific crime.

"We’re shocked. He is nice, a quiet brother,” the 30-year-old woman told The Daily Beast.

Ali Alissa says he doesn’t believe his brother’s alleged attack was a political statment but “mental illnesss.”

“The guy used to get bullied a lot in high school, he was like an outgoing kid but after he went to high school and got bullied a lot, he started becoming anti-social.”

Tuesday, the Boulder Police Department released the names of the ten people killed Monday.

They include Denny Strong, 20; Neven Stanisic, 23; Rikki Olds, 25; Tralona Bartkowika, 49; Suzanne Fountain, 59; Teri Leiker, 51; Boulder Police Officer Eric Talley, 51; Kevin Mahoney, 61; Lynn Murray, 62; Jody Waters, 65.
