According to a criminal complaint, gunfire was heard in the discount store after Hendrickson’s girlfriend got into an argument with an employee, who informed her, for the first time, that her boyfriend was a sex offender. Indeed, officials say Hendrickson was convicted of rape in 2010.

After getting a call about this from his girlfriend, Hendrickson quickly made his way to the store and confronted the employee. The two got into a fight, and the manager forced Hendrickson to leave the store.

Shortly after, he returned with a gun, the criminal complaint states. Witnesses said he shot 69-year-old Donald Hortsch in the head. Hortsch died at the scene. The other victim, a 26-year-old man, said Hendrickson that shot him twice, once in his right leg and once in his abdomen.
