Christopher Bernard Wilder (March 13, 1945 – April 13, 1984), also known as the Beauty Queen Killer and the Snapshot Killer, was an Australian-American serial killer[1] who abducted and raped at least twelve young women and girls, torturing and killing at least eight of them during a six-week, cross-country crime spree in the United States in early 1984. Wilder's series of murders began in Florida on February 26, 1984, and continued across the country through Texas, Oklahoma, Colorado, Nevada and California, with attempted abductions in Washington and New York. Wilder was killed during a struggle with police in New Hampshire on April 13, 1984. Since his death, he has also been considered a suspect in many unsolved murders, including the unsolved 1965 murder of two teenaged girls in his native Sydney.
