Suspect in Boise mall shooting dies of injuries
By Jesús Jiménez
The lone suspect in a shooting at a mall in Boise, Idaho, on Monday that killed two people died Tuesday of injuries he received in an exchange of gunfire with police, according to police.
Authorities were still investigating the motive for the shooting, in which they said the suspect, Jacob Bergquist, 27, of Boise, fatally shot a security guard, Jo Acker, 26, of Caldwell, Idaho, and Roberto Padilla Arguelles, 49, of Rupert, Idaho, at Boise Towne Square.
At a news conference Tuesday, Chief Ryan Lee of the Boise Police Department said Bergquist had frequented the mall and was known to mall security for calls categorized as disorderly conduct, trespassing and disruptive behavior.
Lee said investigators were interviewing people who knew Bergquist and examining social media to try to understand what led to the attack.
“We’re still very early on in that investigation,” he said, “and there’s not much information that I can share relative to that.”
Four people were injured in the shooting, including a 23-year-old woman and a 52-year-old woman who were injured inside the mall, and a 68-year-old woman who was shot in her vehicle outside the mall, according to the Boise police. All three women had non-life-threatening injuries, they said.
The fourth person injured by gunfire was a police officer who was treated at a hospital and released Monday.
Officers responded to reports of shots fired at the mall about 1:50 p.m. Monday, police said. Callers told dispatchers that an armed man had fired several shots inside the mall, according to the police.
A security guard on the first level of the two-story mall initially “contacted” the suspect near a department store on the west side of the mall. The gunman fatally shot the guard.
Police said Bergquist then fired several rounds inside the mall, including shots that struck a glass elevator and a second person, who later died at a hospital. The gunman continued firing, injuring four other people, they said.
When the police arrived at Boise Towne Square, they saw the gunman running out of the mall. The gunman and the police exchanged gunfire. An officer was shot through the window of his vehicle, police said.
Police said 18 used shell casings were found inside the mall, and that they had executed a search warrant Tuesday at a home in Boise as part of the investigation.
A man who was fleeing the mall after the attack was injured when he fell and was treated at a hospital, police said. Lee said the number of injuries could rise as the investigation continues, given the number of people who “self-evacuated, running for their lives.”
