The Jacksonville Sheriff's Office says the incident happened Saturday evening when Heydi Rivas Villanueva was sitting in a vehicle waiting for someone with her father to come out of a restaurant.
While she waited, a gunfire erupted between two unrelated groups, and a stray bullet struck Villanueva in the head.
Authorities say they are working to identify the two individuals seen in one of the videos.
A reward of $11,000 has been established for anyone with information in regards to the case.
