Accused Boulder mass murderer Ahmad Al Aliwi Alissa stripped off his clothes before he was arrested — and then asked to speak to his mom as he surrendered to authorities, according to new court documents.
The moments following the Monday afternoon slaughter of 10 people at the King Soopers grocery store emerged in a new affidavit released Tuesday — along with chilling details from witnesses who watched as he allegedly gunned down victims.
After SWAT members burst into the supermarket, they found Boulder police officer Eric Talley’s body — with a bullet wound to the head.
A short time later, a bloodied Alissa — who was shot through his upper right thigh — surrendered.
“Alissa had removed all of his clothing and was dressed only in shorts,” the affidavit says.
A green tactical vest, rifle, semi-automatic handgun, pair of jeans and a long-sleeve T-shirt were later found at the scene, the affidavit says.
Aerial footage captured the dramatic scene — a handcuffed Alissa half-naked and soaked in blood as he’s being hauled away by officers.
A sergeant asked Alissa, 21, if there were any other suspects.
“The suspect did not answer questions, though he asked to speak to his mother,” the document says.
Police said there was no indication that Alissa was drunk or high on drugs, according to the affidavit. The alleged shooter told paramedics that “he was not using any medications.”
In addition to the weapons and clothing, found at the scene was a black Mercedes C, registered to a man believed to be Alissa’s brother.
“There was much blood around the items,” the affidavit says, adding that a green rifle case was found in the sedan.
The five-page document includes other details from the scene, including from 911 calls that poured in with reports of “parties down” and witnesses who believed the gunman was wearing body armor and toting what looked like a black AR-15.
Several witnesses described Alissa as a chubby “white male.”
King Soopers employees told police that they watched as Alissa allegedly shot an elderly man in the parking lot.
“The suspect then walked up to the elderly man, stood over him and shot him multiple additional times,” the affidavit says.
Another witness claimed Alissa “shot a male in a vehicle” and then shot at others before heading into the store.
Alissa also allegedly opened fire on Boulder police officer Richard Steidell, who reported seeing him “moving from his left to right, while shooting,” the court papers say.
Investigators learned that Alissa had purchased a Ruger AR-556 pistol on March 16 — six days before the mass shooting.
