Police say the suspect in a mass shooting at a Tuscaloosa bar had been fired from his job following a fistfight. Police say 44-year old Nathan Wilkins told them in April he was was angry about his firing and that he was pressing assault charges against the co-worker with whom he fought. Wilkins was expected to make a court appearance Wednesday. He's charged with 18 counts of attempted murder for the shootings that injured 17 people at the Copper Top Bar, and an earlier shooting in Northport that injured a 30-year old man. Wilkins is also suspected of setting fires at his former workplace, Capstone Oilfield in Brookwood. He is being held on $2-million dollars bond.
