EVERYTHING HAD BEEN FIXED 🔪
An 83 Year Old Man Was Found Dead In His Dining Room
His 45 Year Old Son Had Killed Him
The Son Was Unmarried And Lived With His Father
Afterward He Phoned His Sister And His Brother In Law
He Told Them Everything Had Been Fixed
Then He Rang A Neighbor's Doorbell
The Neighbors Did Not Answer
He Stayed On Their Stairs Confused And Holding A Tattered Towel
In The Dining Room His Father Held A Bread Knife Loosely
Records Showed The Son Had Been In Outpatient Psychiatric Care
Over The Last 3 Years He Had Followed His Treatment Less Closely
The Day Before The Killing His Father Had Asked For A Medical Exam
Apparently It Was Because He Had Stopped Keeping To His Treatment
After The Killing An Expert Examined The Son
The Diagnosis Was Schizoaffective Disorder With A Paranoid Delusion
He Said His Father Had Been Replaced By An Impostor
In His Account The Impostor Had Threatened Both His Father And Him
At Times He Saw The Impostor As An Object Like A Sack Of Potatoes
