A 47-year-old O’Fallon man was killed Thursday during a work-related accident at Southern Illinois University Edwardsville.
Madison County Coroner Stephen Nonn identified the deceased as Roger R. Kolweier.
Kolweier was working for Keller Construction at the time of the accident. He and a co-worker were on Stadium Road off New Poag Road in Edwardsville, working on a frontage road on the SIUE campus.

He had been driving a heavy piece of machinery with a roller attached. Authorities said it appears that a portion of the road gave out, causing the machine to flip. Kolweier attempted to jump from the machine but became pinned underneath it at the bottom of a creek, according to the coroner’s office.
An off-duty Illinois State Trooper and his wife, who is a nurse, were flagged down by the co-worker to help. They performed first aid on him until Edwardsville Fire and EMS personnel arrived, but were unable to save him.
Kolweier was pronounced dead at 4:45 p.m. Thursday by Madison County Coroner’s Investigator Diondra Horner.
A representative of Keller Construction in Glen Carbon could not be reached for comment.
The death is under investigation by the SIUE Police Department. Representatives from the Occupational Safety and Health Administration will also be investigating the accident.
Nonn said Kolweier died of blunt chest and abdominal trauma. Routine toxicological testing will be performed.
A visitation for Kolweier will be held from 4 to 8 p.m. Monday at Faith Family Church in Shiloh. A funeral service will be held at 2 p.m. Tuesday at the church. Wolfersberger Funeral Home in O’Fallon is handling the arrangements.
