NORTH PORT, Fla.- A family tragedy has shaken an entire North Port neighborhood.

A grandmother was hit and killed by a minivan driven by her 13-year-old granddaughter Wednesday evening, in front of the family's home on McKibben Drive.

Investigators said 68-year-old Judith Jellema had asked her granddaughter to fix a crooked parking job in the driveway.  They said Jellema was standing next to the open driver's side door when the girl put the car in reverse, and was knocked to the ground.  When the girl tried to stop and help her grandmother, investigators say she accidentally hit the accelerator and ran over Jellema.

Jellema was airlifted to Blake Memorial Hospital in Bradenton, where she died.

Police told WINK News they likely won't file criminal charges.

"That was a decision that was made from an adult, being the decedent, being the grandmother, she was instructed to do so," said Assistant Chief Anthony Sirianni with the North Port Police Department.  "If there's anybody at fault, criminally, it's the decedent, unfortunately."

Neighbors declined to speak on camera with WINK News, out of respect to the family's wishes to grieve privately.
