The Mormon sex in chains case was a widely reported scandal involving a sexual assault by an American woman, Joyce McKinney, on a young American male Mormon missionary, Kirk Anderson, in England in 1977. According to Anderson, he had been abducted by McKinney from the steps of a church meetinghouse, chained to a bed and raped by her. Before the case could be tried, McKinney jumped bail and fled to America.
A young Mormon missionary named Kirk Anderson went missing in 1977, in Ewell, Surrey, after he was abducted from the steps of a meetinghouse of The Church of Jesus Christ of Latter-day Saints. A few days later a freed Anderson made a report to the police that he had been abducted, driven to Devon, and imprisoned against his will, chained to a bed in a cottage, where Joyce Bernann McKinney (b. August 1949) — a former (1973) Miss Wyoming World (as Joy McKinney) — had abducted, attempted to seduce, and then raped him. The case became known by many sobriquets, including "The Mormon sex in chains case" and "The Case of the Manacled Mormon."
On 19 September 1977 McKinney was arrested and charged, but vigorously denied the charges. While being taken to Epsom for a court appearance, she held a notice up at the window of the police vehicle saying, "Kirk left with me willingly!" Press reports and McKinney's lawyer refer to the size differential between McKinney, described as slightly built, and Anderson, described as substantially larger.
Along with Keith May, her co-conspirator, McKinney jumped bail and fled the country. On 18 July 1979, they were both arrested in the United States by the FBI on charges of making false statements in order to obtain passports. They both received suspended sentences.
No extradition proceedings were instituted by Britain, and the English court sentenced McKinney in absentia to a year in jail. Under the then-Sexual Offences Act 1956, due to the victim's gender, there was no crime of rape committed, though indecent assault of a man applied.
