Roberto Padilla Arguelles, 49, of Rupert, Idaho, was killed on October 25, 2021, while shopping for family gifts at Boise Towne Square mall. A truck driver who split time between Idaho and Zacatecas, Mexico, he had been planning to return to his wife and three children in two weeks. Witnesses say he was struck while on an escalator during a shooting that began when a man confronted by a security guard opened fire.

The shooter, identified as 27-year-old Jacob Bergquist of Boise, fired roughly 18 rounds inside the mall, killing security guard Jo Acker after she confronted him and wounding several others before exchanging gunfire with police outside. Bergquist later died at a hospital from what was reported as a self-inflicted gunshot wound. Investigators noted prior encounters between Bergquist and mall security over his possession of firearms and that he was a convicted felon prohibited from possessing guns under federal law.

Arguelles’s family has filed a lawsuit naming the mall owners, the security company, the City of Boise, Ada County, the Ada County Prosecutor’s Office, and the Idaho State Police, alleging negligence for failing to act despite Bergquist’s known behavior. If anyone knew Roberto or remembers details from that day at the mall, please share what you know.
