Granny Killer

John Wayne Glover-also known as the "Granny Killer"-was a serial killer who was active in Sydney, Australia, between 1989 and 1990 who murdered at least six-and as many as 13-elderly females after hitting them with a claw hammer and then ritually strangling them with their own pantyhose. It was widely believed that Glover's victims represented his mother and mother-in-law who he blamed for his misdeeds.
He was ultimately sentenced to six life sentences without any possibility of release. Glover committed suicide by hanging himself on 9 September 2005.
