Notorious serial killer Ted Bundy was infamous for taking the lives of more than 30 women between 1974 and 1978. He was also known for being extremely handsome and charming. Perhaps that's why in 1980, a former coworker of Bundy's, Carole Ann Boone, married him after he famously proposed to her in court.
In fact, Bundy married her right then and there, using a bizarre loophole in Florida law stating that just a declaration of marriage in the presence of a judge constitutes a legal marriage. In 1982, Boone gave birth to Bundy's alleged daughter, even though conjugal visits weren't allowed in his Florida prison. Bundy was executed in 1989, but his marriage dissolved in 1986 at Boone's request.
