BUTLER COUNTY, Ala. (WIAT) — The deadly crash on I-65 Saturday afternoon killed one adult and nine children, eight of which were riding in a Tallapoosa County Sheriff Youth Ranch bus, authorities say.

There were approximately 17 vehicles involved in the accident. It happened on I-65 northbound at the 138-mile marker just north of Greenville.

According to the Butler County Coroner, the eight children that died in the bus were within the age range of 3 to 17. A bystander was able to remove the bus driver from the vehicle, but couldn’t save any of the passengers due the vehicle being on fire.

The other two deceased were riding in a black SUV. Cody Fox, 29, died from the impact of the crash and his 9-month-old daughter later died at a regional medical center.

The exact cause of the accident is unknown at this time, although officials say that they believe it was weather related.

“Investigating fatal crashes is one of the most difficult responsibilities of the Alabama Law Enforcement Agency,” ALEA’s Secretary of Law Enforcement Hal Taylor said in a written statement. “Yesterday (Saturday) was an extremely heartbreaking day for the state of Alabama as 10 lives were tragically lost in one horrific event. I would like to offer my sincerest condolences to the friends and families of loved ones lost in Saturday’s terrible crash, as well as my gratitude to all of the first responders and volunteers who quickly and valiantly responded to the scene. It was a difficult and unimaginable scene for many, and our thoughts and prayers are with all involved as we continue to investigate and provide closure for those affected.”

ALEA Troopers and investigators from the National Traffic Safety Board will continue to investigate.
