Bannan was accused of shooting and injuring a woman as she unlocked her separate office at Bannan’s own business, Black Lab Sports, in October 2019. Ashley Marie was shot in the shoulder as she stood stood at the office door. Bannan, according to case documents, was inside the locked office before Marie arrived.

Court documents indicate that Bannan made statements that the Russian mob were after him after the shooting. They also state that he also had in his possession a rolled up $20 bill that contained cocaine residue.

Bannan pleaded not guilty by reason of insanity to all charges.
