North Side Tragedy

A nightmare scenario:

• A retired Chicago homicide detective shot and killed his son after mistaking him for an intruder in his Northwest Side apartment early this morning, according to police and family.
  
  Michael Griffin, 48, was found shot once in the head a little after midnight in his father’s home in the 5300 block of North Delphia Avenue, police said.
  
  An autopsy performed today found Griffin died of a gunshot wound to the face and his death was declared a homicide, according to the Cook County medical examiner's office.
  
  The father, James Griffin, 77, was taken to Resurrection Hospital after complaining of chest pains, relatives said. No charges have been announced by police.

Thoughts and prayers for the family.
