Rodney Francis Cameron was dubbed 'The Lonely Hearts Killer' after he used a radio match-making program in 1990 to lure an unsuspecting woman to her death. Incredibly, he had only just been released from prison for two other killings in 1974. Cameron's psychopathic tendencies appeared early in his life. At the age of ten, he tried to strangle a young girl.
On July 10, 2001, Sef Gonzales murdered his sister Clodine 18; mother Mary Loiva Josephine 43, and his father Teddy 46, in their North Ryde home. He claimed that he had discovered the bodies when he arrived home, and that racist graffiti was sprayed on the wall. However, as more evidence was unearthed, police started to see Sef as a very likely suspect.
