As posted on facebook. Teehee is her nickname for the Aveo. Ari's description of the accident:

"There were no lights. It was by the Shelton, Trap Falls Reservoir. I just got
out of class. She hit me on the driver's/my side. I was turning left, the sun
was in my eyes and I didn't see her till the last moment. If she had actually
used her brakes, we could have avoided it, but no. x.x No...that would have been
smart. Now I am sad, achey, etc. and Teehee and her Accord are in Heaven. The
cops said they weren't sure about her car, but we all could tell that Teehee was
gone. The left wheel is diagonal and when mom got there after the ambulance took
me to Griffin, she said there were fluids EVERYWHERE."
