According to investigators from the Cobb County Police Department’s Selective Traffic Enforcement Program (STEP) Unit, on July 5 at about 1 a.m., Prindle was a passenger in the back seat of a silver 2001 Hyundai Santa Fe, traveling northbound on Johnson Ferry Road toward Sewell Mill Road. She rolled down the window and hung out, “yelling and screaming.”

Prindle fell out the window and struck the pavement.  She was transported to WellStar Kennestone Hospital, where she was admitted to Intensive Care.

She remained hospitalized and was pronounced dead on July 25.
