A Petersburg man is dead, allegedly stabbed by his half-brother as they were in a dispute in a pick-up truck in western Illinois.
Dead is Dennis Coffman, 27. Joseph Coffman, 28, of Fort McDowell, Ariz., is charged with aggravated battery and is jailed in Pike County. The sheriff there says his department fielded a 911 call reporting a stabbing in a vehicle on Interstate 72 near the Mississippi River.
Authorities later found the Coffmans in a pickup truck that had drifted onto the grass along the interstate, near Hull.
