Police say the Lexington girl took the keys of her mother's Chevrolet Suburban while the woman slept, then used a pink plastic step stool to climb into the SUV. Police Lt. Chris Van Brackel told the Lexington Herald-Leader the girl backed it out of the driveway and into a loaded school bus, but no one was injured. After that, she drove forward into her yard and jumped out of it, receiving only a scratch on her ankle as an injury. Brackel said the SUV then rolled down a hill and hit a parked church van. The bus received minimal damage.
