The Supreme Court of New South Wales has found Leonard Warwick guilty of three murders and multiple bombings in the 1980s following a feud with his ex-wife.
Warwick, a 73 year old former firefighter, was arrested in 2015 and pleaded not guilty to more than 20 charges. He would found guilty of all offences except the alleged shooting murder of his brother-in-law in 1980.
Warwick was found guilty of the shooting of Justice David Opas in his Woollahra front yard in 1980, after hearing Warwick's Court matter.
Justice Richard Gee then heard Warwick's Court matter, before he was injured and his home in Belrose was destroyed by a bomb in 1984. The Family Court Registry building in Parramatta, where Warwick's matter was heard, was also bombed in 1984.
Justice Ray Watson's home was bombed in 1984 as well, and Justice Watson's wife, Pearl, was killed when the explosive blew up as she entered her home.
Minister Graham Wykes was killed during an explosion at a Jehovah's Witness church hall in 1985, that also injured several people inside.
Warwick will return to Court for sentencing in August this year.
