Leonard Warwick has been found guilty for a number of bombings committed during the 1980’s, including the Family Court bombing and the Jehovah’s Witnesses Casula Congregation Kingdom Hall bombing on 21 July 1985 which killed the public speaker, Graham Wykes, and injured 13 others.

Side Note: I have been closely following this story for 35 years now, including the past few years of Supreme Court hearings, much of which dealt with the Jehovah’s Witnesses Kingdom Hall bombing.
