Police knew from the beginning that David Jaber was the main suspect in his father's murder.

Neighbors at Fred Jaber's retirement apartment complex found the 79-year-old with a butcher knife in his back.

Jaber claims "His father had been molesting him since he was 4 or 5-years-old. Part of the condition of David moving in was that he'd perform oral sex on his father."

In the court documents, David Jaber told police on June 26 he snapped. He talked to his mother on the phone to tell her about the years of alleged abuse. Court documents say she told him she didn't care.
