The suspect at the center of Monday afternoon’s mass shooting at the Boise Towne Square Mall died on Tuesday, the Ada County coroner said. The man was identified as 27-year-old Jacob Bergquist. Police said he’d had previous interaction with law enforcement but no further details were given.
Authorities have also identified the two victims as security guard Jo Acker, 27, of Caldwell, and Roberto Padilla Arguelles, 49, of Rupert. Four other people were injured, three of whom are women with non-life-threatening injuries. Acker’s sister, Shawna Lannigan, took to Facebook on Tuesday to write that Acker, who identified as a trans woman, had an “enormous heart of gold,” and she couldn’t “put into words how completely devastated and shattered” she was. A friend, Dominique Cairistiona, said Acker was “absolutely adored by everyone who knew her... Her heart was bigger than the sun.”
