David Taylor said since winning the lottery jackpot with his wife, Colleen, his family has been the target of tragedy including the shooting death of his 15-year-old grandson this week, The Daily Telegraph newspaper in Sydney said in its Saturday edition.
"Torn apart, this has torn us apart," Taylor, 57, of the town of Port Macquarie, said. "We used to be a close family but there's no money left and no family left. The win has destroyed us."
Taylor said his grandson was killed Wednesday while playing with a loaded firearm along with Taylor's 15-year-old son, William.
"They don't know anything about guns. As William handed it to Joshua, it accidentally went off," Taylor said of the death.
The Daily Telegraph said the family was previously involved in a fatal shooting following the 2001 death of a Sydney man who was killed by an olive farm tenant Taylor attempted to evict.
