Christopher Bernard Wilder (March 13, 1945 – April 13, 1984), also known as The Beauty Queen Killer, was a serial killer from Australia who abducted and raped at least twelve women, killing at least eight of them, during a six-week cross-country crime spree in the United States of America in early 1984. His series of murders began in Florida on February 26, 1984, and continued across the country through Texas, Oklahoma, Colorado, Nevada, and California, and attempted abductions in Washington State and New York before he was killed during a struggle with police in New Hampshire on April 13, 1984.
He is also believed to have raped two girls, aged 10 and 12, in Florida in 1983. Since his death, Wilder has also been considered a suspect in the unsolved 1965 murder of two teenage girls in Sydney, Australia, where he had lived from his birth until 1965.
On April 13, 1980, Wilder attacked and attempted to abduct 17-year-old Carla Hendry in Beverly, Massachusetts but she managed to escape.
While visiting his parents in Australia in 1982, Wilder was charged with sexual offenses against two 15-year-old girls whom he had forced to pose nude. His parents posted bail and he was allowed to return to Florida to await trial, but court delays prevented his case from ever being heard, as the eventual initial hearing date of April 1984 came after his death.
In early 1984, he began a bloody, six-week, cross-country crime spree in the United States. He would leave in his wake a total of 8-9 female murder victims.
