A 15-year-old Jemison girl was killed after jumping from an Interstate overpass early Wednesday morning in what the Chilton County Sheriff’s Department has ruled as a suicide.

The victim, reportedly a student of Jemison High School, jumped from the Chilton County Road 48 overpass onto the southbound lane of Interstate 65 near the 217-mile marker shortly before 7 a.m.

One lane of I-65 southbound was shut down for approximately two hours. No vehicles were involved.

“It’s a traumatic thing for the family,” said Chilton County Sheriff Kevin Davis.

Union Grove Fire Department was dispatched to the scene, along with the Chilton County Sheriff’s Department, Alabama State Troopers, the Chilton County Coroner’s Office and Care Ambulance.

The sheriff’s department is the lead investigating agency in the case.
