A Peoria man is now facing murder charges for the death of his elderly father.
Mark Runyon already faced years in prison for allegedly failing to properly care for his father, Frank.
Earlier this month, 74 year-old Frank Runyon died in the hospital following injuries to his face and bleeding of the brain.
Now, authorities are saying Mark Runyon caused those injuries by punching his father in the face.
Runyon is due in court on Thursday for his arraignment.
