PIKE COUNTY, Ga. — Authorities say a 22-year-old died after losing control of her car in a violent wreck. 

It happened around 6 a.m. Monday, but authorities say they didn't discover the crash until nearly 7 hours later.

According to the Pike County Sheriff's Office, Tara Corley left her home Monday morning for work and was going north on Hwy 19 near Patton Road. 

Somehow, Corley lost control of her Toyota 4Runner and slammed into a propane tank. That caused the tank to overturn and collide into an advertising sign that collapsed onto the vehicle. 

Although the crash happened much earlier in the day, deputies said they didn't get word to respond until 1 p.m. because the wreckage was hidden from the roadway. 

The sheriff’s office's traffic investigators will continue working to determine the cause of this accident.
