Paterson's body was found in water below the McLaren Falls bridge about 11.30am on Friday July 12.
Prior to Justice Sarah Katz beginning her audio visual link callover, Wilson started yelling out to a member of Paterson's family, "sieg f****** heil", "I'll f*** you up, arsehole" and "I will have the last laugh".
Seconds later, he stormed the dock and made it through to the second row of the lawyer's benches before he was finally restrained by staff from Corrections, court security and detectives who were supporting the family in court.
