Mann's ex-girlfriend allegedly told investigators that on Nov. 11, he appeared at her apartment with a handgun after she spoke to his girlfriend about his criminal history, KSAT-TV reported, citing an arrest affidavit.

County records indicate Mann, of San Antonio, was arrested in October 2015 on suspicion of assault causing bodily injury.

During a discussion about the topic with his ex, Mann reportedly became upset and hit her in the head with his gun.
