BROOKWOOD, Ala. (AP) — The suspect in a shooting rampage at an Alabama bar had been fired from his job after a fistfight with a co-worker this spring, police said Wednesday.

Nathan Van Wilkins told police in April he was angry about his firing, and he was pressing assault charges against the other man, said Brookwood Assistant Police Chief Jimmy Sellers. Wilkins signed a warrant against the other man, who had also been fired but not arrested.

It's not clear what role the firing from Capstone Oilfield may have played in the shootings early Tuesday that wounded 17 at a bar. Sellers says he's not aware of any connection between the shooting victims and the company.
