The gunman who killed one person and wounded two others at a Virginia university campus on Thursday had previously been imprisoned for trying to support ISIS, sources told CBS News.

Law enforcement sources identified the gunman in the Old Dominion University shooting in Norfolk as Mohamed Bailor Jalloh, a former Virginia National Guardsman who pleaded guilty in October 2016 to attempting to provide material support to the terror group ISIS. He was sentenced to 11 years in prison and was released early in December 2024, according to his Federal Bureau of Prisons record.

Jalloh was also killed in the shooting.

The shooter walked into a class at Constant Hall, which is part of the College of Business at Old Dominion, and asked if it was an ROTC class, a law enforcement source told CBS News. When someone responded that it was, the shooter opened fire, fatally injuring the class instructor, who was a retired Army officer. The shooting is being investigated as a terror-related attack.
