Scenes after a shooting at the Table Mesa Dr. King Soopers grocery store in Boulder, Colorado, on Monday, March 22, 2021. (Steve Peterson, Special to The Colorado Sun)

The 22-year-old Arvada man accused of killing 10 people, including a police officer, at a Boulder King Soopers last month has been charged with 43 additional counts, including 10 counts alleging that he had a large-capacity ammunition magazine.

The other new counts against Ahmad Al Aliwi Alissa include 32 new allegations of attempted first-degree murder, mostly in connection with additional victims who were previously unnamed in court records.

Many of the newly named victims are police officers who responded to the March 22 shooting.

The suspect also faces a new count of first-degree assault in connection to a woman who was seriously hurt in the attack. Authorities originally said there were no injuries beyond the 10 people who were killed and the gunman, who was shot by a responding officer but not seriously hurt.

The alleged gunman was already facing 10 first-degree murder counts in connection with the shooting. Authorities say he used a high-powered AR-556 pistol that he had purchased legally.

Colorado lawmakers in 2013 banned gun magazines that hold more than 15 rounds in the wake of the Aurora theater shooting. They are still readily available, however, at Colorado gun stores.

Boulder County District Attorney Michael Dougherty said Thursday during a news conference in Boulder that authorities have no evidence the 10 high-capacity magazines that the alleged gunman had either with him or in his vehicle during the attack were purchased illegally. However, Dougherty said investigators are still looking into the origin of the magazines.

He declined to elaborate. “I’m not going to share, just yet, the details around where each one of those was bought,” Dougherty said.

Dougherty said authorities still have no information on a potential motive for the attack. It’s not believed that the gunman visited the King Soopers he attacked before his deadly rampage.

“The investigation is still in its early stages, and we still have a long way to go,” Dougherty said.

There were at least 115 people in the King Soopers when the attack began, as well as 25 people in the grocery store’s parking lot.

The 10 people killed in the shooting were:

  • Denny Stong, 20
  • Neven Stanisic, 23
  • Rikki Olds, 25
  • Tralona Bartkowiak, 49
  • Boulder Officer Eric Talley, 51
  • Suzanne Fountain, 59
  • Teri Leiker, 51
  • Kevin Mahoney, 61
  • Lynn Murray, 62
  • Jodi Waters, 65

Police officer Eric Talley was killed within seconds of entering the store, Dougherty said. Talley was among three officers who rushed into the King Soopers after arriving at the scene. About 30 seconds later, another wave of officers entered the store.

Talley was the last person killed in the attack. Stanisic was the first civilian killed in the attack and Fountain was the last.

The officer who shot the gunman fired seven rounds at the suspect from a handgun.

The alleged gunman isn’t due back in court until next month. He has a May 25 court date and is expected to face additional charges.

King Soopers allowed victims and police officers to return to the crime scene over the weekend if they wanted to as part of their healing process.

State lawmakers are set in the coming days to unveil a package of new gun control bills in response to the shooting. Among the measures that have been discussed is one banning assault weapons, though it’s not clear there is enough political willpower at the Capitol to move forward with such legislation.
