Jacob Bergquist, 26, allegedly walked into Boise Towne Square on the afternoon of Oct. 25 with multiple guns. 

A security guard approached Bergquist and "the suspect began to walk away, then turned back and shot the security officer," according to the Boise Police Department.

Jo Acker, a 26-year-old security guard and U.S. Army veteran, was killed. Roberto Padilla Arguelles, 49, was also shot and killed as he was riding an escalator inside the mall. 

The suspect died at a local hospital the morning after the shooting. 

A prosecutor said in court last Wednesday that after Acker was shot, Scarbrough "approached the dying security guard at the mall" and stole her rings, a gun belt, and other property, the Idaho Statesman reports

Scarbrough also allegedly was caught by a janitor "rummaging around in his office," according to the local news outlet.

Acker's sister, Shawna Lannigan, wrote on Facebook that Acker "always wanted to protect others."

"I can’t even put into words how completely devastated and shattered I am," Lannigan wrote. "You were and are and always will be a hero. I love you to the ends of this earth and beyond."
