On November 27, 1980, in what became a famous case in Puerto Rico, after having injected himself with cocaine, de Jesús was involved in a traffic dispute with 17-year-old Roberto Cintron Gonzalez, which ended in de Jesús fatally shooting Gonzalez in the head. De Jesús was sentenced to life in prison. There, he excelled in another sport, baseball, making the Puerto Rico penal system all star team three times. In 1984, he became a born-again Christian and started to turn his life around, becoming a preacher.
