Retired Suffolk Detective Fatally Shot by Son Following Domestic Dispute

Christopher Miller, 43, has pleaded 'not guilty by insanity' after allegedly killing his father, John Miller, in their Dix Hills, NY home.

Christopher Miller, recently divorced, had moved back into his father's home, where tensions reportedly escalated.
The fatal incident occurred on March 19 after an argument during which Christopher retrieved a shotgun and allegedly shot his father multiple times.
John Miller, a respected retired Suffolk County detective and long-serving firefighter, had reported his son missing just one day before the shooting.
Christopher fled the scene and was later apprehended in a nearby shed; he has been charged with second-degree murder and is being held without bail.
The case raises questions about mental health after Christopher entered a 'not guilty by insanity' plea during his arraignment on March 20.
