NEWTON COUNTY, Ga. — The body of Shanequa Sullivan, an airport worker with autism, turned up in a river 33 days after she went missing on Feb. 4.
The Newton County Coroner just released her cause of death - homicidal violence.
Sullivan's manner of death was ruled a homicide, meaning, she was killed.

Grainy surveillance video shows her last known steps - trying to get home from her job at Hartsfield-Jackson International Airport. A boater found her body in the Yellow River a month later.
Lead investigator on the case for the Newton County Sheriff’s Office Jeff Alexander once told 11Alive that evidence showed she was dead before she was put in the river. But where she was found is thick with brush and almost an hour away from her job - a very bizarre place to end up.
The case and the way police officers responded has been called into question. The Atlanta Police Department failed to save all of the surveillance video for Atlanta's airport from the day she went missing. Most of the surveillance video from the airport showing her last movements was automatically deleted from the system before it was collected.
The boater who found her body said it affected him.
