"The Killer Clown," was a husband and father, but he was also a repeated sex offender. 



He was caught sexually assaulting two teenage boys in 1968 and sentenced to 10 years in jail, but due to his exemplary behavior as an inmate he was released on parole after serving just 18 months.  

Once he was released from jail, Gacy briefly remarried (they divorced when she discovered that he was secretly gay) and became a popular and jovial member of society.
