The girl’s family told police she was en route to a babysitting job at the time of the crash and wasn’t expected home until late that night. It’s not clear if any attempts were made to contact the girl’s parents when she didn’t show up for babysitting.

Police weren’t able to identify the girl right away and issued her picture to media outlets in hopes of finding her family. She was finally identified Saturday morning after her grandmother saw the girl’s photo on the news and immediately contacted authorities and the girl’s mother.
