Disappearance of Ian Richardson

On April 30, 1992, 16-year-old Ian Richardson disappeared from Denver Colorado. He lived in the northern section of the city and frequented the Idaho Springs area. Foul play is suspected in this case. 

John Taylor is a prime suspect in Ian's disappearance as he was sexually abusing him since he was 13 until he disappeared. In 1991 Ian told police that John Taylor had sexually abused him in 1989 during a camping trip and again in 1990. John was then charged with child sexual abuse and harboring a runaway. These charges were dismissed after Ian recanted his story. 

In 1992 Ian accused John again, but this time of circumcising him while he was passed out drunk. John refuted stating that Ian had done it to himself. Ian would tell a counselor that he was being threatened and that if he testified he or his family would be harmed. He would then allegedly punch John in the face later. This would cause Ian to be charged with assault in juvenile court. He would disappear soon after. 

 John Taylor would admit that he had in fact sexually abused Ian. He claimed that Ian had killed himself. In 2002 however, a friend of his went to the police to tell them that John had in fact shot Ian and then chemically cremated him. John is a chemist and had the knowledge to do so.
