She died from her injuries and blood loss in a driveway accident on May 21, 2008. Will Chapman was pulling into the driveway of their house after he auditioned for a musical at school and Maria Sue was running to meet him so she could ask him to put her on the monkey bars. They didn't see each other in time, and he accidentally ran over her. She was airlifted to Vanderbilt Children's Hospital. EMS paramedics attempted to resuscitate her en route the hospital but were unsuccessful. Maria was pronounced dead on arrival.
