MORTON — One person was killed in a traffic crash Wednesday on South Main Street on the ramp to southbound Interstate 155, and a child was injured.

A news release from the Tazewell County Sheriff’s Office identified the injured passenger as a 3-year-old child who suffered injuries that were not life-threatening.

Killed in the crash was Renae L. Hanson, 34, of Tremont, according to the Tazewell County Coroner’s Office. An autopsy was scheduled for Thursday.

Hanson was entering the I-155 southbound ramp from South Main Street about 7:40 p.m. when her vehicle struck a guardrail on the south side of the interchange overpass and left the roadway on the west side of the on-ramp, said Sheriff’s Capt. Craig Catton. The vehicle rolled over and ejected the driver, who was not restrained, according to the Sheriff’s Office.

The crash remains under investigation by multiple agencies.
