UPDATE: A 5-year-old boy and his father are dead in an apparent murder-suicide in Dixon, Illinois.

Police were called just after 3:30 p.m. Monday, September 18th to the 1000 block of Fargo Avenue for reports of shots being fired. Officers made entry into the home and found a door barricaded shut on the 2nd floor. After forcing entry into the room, officers found 5-year-old Christopher Michaels dead from a gunshot wound. Christopher's father, Robert Michaels, was also found with a gunshot wound to his head. Police say he was breathing, but unresponsive. The father was taken to a local hospital, then flown to Rockford Hospital and later pronounced dead.

Police say Robert Michaels has been under investigation by the DIxon Police Department since September 12th for allegations of child sexual abuse. Investigators say the reported victim was not his son, Christopher.

Dixon Police Chief Langloss released this statement, "Our heart goes out to the family members who have suffered this horrific tragedy. Our officers feel your pain. There is nothing more difficult for a police officer than seeing a young child's life being taken in such a senseless manner. This is by far the worst situation our officers have been involved in."

Dixon police officials say the matter remains under investigation with the assistance from the Illinois State Police Crime Scene Investigations Unit.
