HULL, Ill. — A Petersburg, Ill., man is dead and an Arizona man is in custody after an incident early Saturday morning in Pike County.

Dennis S. Coffman, 47, of Petersburg was pronounced dead at Hannibal (Mo.) Regional Hospital from apparent knife wound injuries suffered in an altercation that is believed to have taken place inside a 2009 Chevrolet Colorado pickup.

Pike County Sheriff Paul Petty said Pike County 911 received an emergency call at 12:54 a.m. Saturday regarding a stabbing inside a motor vehicle on Interstate 72 at Mile Marker 1 near Mark Twain Memorial Bridge. Petty said authorities believe the altercation took place while the vehicle was traveling from Missouri into Illinois.

Upon arrival, law enforcement officers from the Pike County Sheriff’s Department, the Adams County Sheriff’s Department and the Illinois State Police observed two men inside the pickup, which apparently had drifted off the road into the grass on the eastbound side of the interstate — just beyond the exit to Hull.

Dennis Coffman was taken from the scene to Hannibal Regional Hospital, where he was later pronounced dead.

Taken into custody at the scene was Coffman’s half-brother, Joseph M. Coffman, 28, of Fort McDowell, Ariz., who was subsequently charged with aggravated battery in connection with the stabbing.

Petty said Joseph Coffman was taken to the Pike County Jail, where he remains lodged. He is expected to make a court appearance as early as Tuesday.

Petty said further charges against Coffman are expected following a complete review of the case by Pike County State’s Attorney Matt Geotten.

Assisting at the scene were the Adams County Sheriff’s Department, Illinois State Police, Hannibal Police Department, Pike County EMS and Hull-Kinderhook-New Canton Fire & Rescue.

The incident remains under investigation by the Pike County Sheriff’s Department, Illinois State Police and the Pike County state’s attorney’s office.
