Under the laws of the Commonwealth of Virginia, he's looking at this charge:
18.2-57.2. Assault and battery against a family or household member.
Any person who commits an assault and battery against a family or household member shall be guilty of a Class 1 misdemeanor. If convicted previously of two offenses against a family or household member of assault and battery against a family or household member or other offenses, such person is guilty of a Class 6 felony.
As for the charges against him previously, since your Mom did not show up to the court, those charges were dropped & may not even show up in his background. Not sure how VA handles background history in this matter.
