MADISON COUNTY, Tenn. (WKRN) — A 26-year-old Memphis woman and a child are dead after falling from an interstate overpass in Madison County early Monday morning.

The Madison County Sheriff’s Office said deputies responded just after midnight to a crash at the Shell Station on Law Road, just south of exit 93 on Interstate 40 east of Jackson.

While deputies were en route, they said they received additional calls of a female driver attempting to hit the gas pump. Witnesses reported the woman got out of the vehicle with a small child, walked over to the interstate overpass and disappeared.

A few minutes later, deputies said they received a call from a driver stating a “large object” had fallen from the bridge and struck his truck, as he was traveling westbound on I-40.

When deputies arrived, they said they located the bodies of Tonisha Lashay Barker and a child. The child’s age was not disclosed.

A relative confirmed Barker was from Memphis, and identified the child as Johnathan Jones, 21 months.

The incident remains under investigation by the Madison County Sheriff’s Office.
