Long story short, Sharon Kinne was a sociopath woman who had affairs and was having an affair with another married man and decided to kill her husband and the wife of the other man. They didnt have great evidence on her so she was out on bail and escaped to Mexico. In Mexico she went around with pistols and killed a guy and wounded another, she claimed self defense but she was convicted and went to jail. The Mexican jail didnt have enough guards and the guards had a lax environment so during a power outage she was able to escape, and the guards didnt suspect anything until she didnt show up for two different role calls. Mexican authorities issued a manhunt but gave up after a month. That was 1965 and her whereabouts have been unknown ever since. She would be 80 today if still alive. She was fluent in Spanish and Mexican authorities think she escaped to Guatamala with the help of a Mexican boyfriend, however an alternative theory says the family of her victim broke her out of jail so they could kill her.
