Trial for Bridgette Robinson, 46, was scheduled to begin on Monday; however, as part of a plea agreement, Robinson pled no contest to vehicular manslaughter and had a vehicular homicide charge dropped.
She was convicted of vehicular manslaughter and had her sentencing scheduled for August 1. She faces up to 90 days in jail.
Robinson was dropping off students at Woodward Career Technical Center on Sept. 13, 2010 and thought she had set the parking brake when she went to the back of the bus.
Instead, the bus began to roll, hitting and killing Sherry Pettit, 40, an employee of First Care Ambulance, as she was assisting a special needs student.
April Travis, 37, also an employee of First Care, was injured in the accident and taken to the hospital. Two students on the ambulance suffered minor injuries.
