A Baton Rouge man who forced his ex-girlfriend at gunpoint to drive her empty school bus from her home to his almost 6 miles away last year was convicted Monday on federal carjacking and weapons charges, U.S. Attorney Walt Green said.

Jock R. Jones, 38, who pleaded guilty Feb. 2 to possession of a firearm by a convicted felon in the incident, was found guilty Monday by U.S. District Judge Shelly Dick of carjacking and using a firearm during the carjacking.

Jones attacked his ex-girlfriend — an East Baton Rouge Parish school bus driver — outside her home April 14 in the Park Forest area and forced her to drive her bus to his home on Billops Street, police have said.

While forcing her onto the bus, Jones pointed his gun at the woman’s two children and threatened to kill them if they called the police, Green said in citing trial evidence.

Jones released the woman as police were arriving but barricaded himself in his house for several minutes until finally surrendering without incident, police have said.

Dick did not set a sentencing date. Green said Jones faces a substantial prison term.
