Robbie Middleton reportedly developed a type of skin cancer that develops after several grafts. Because of this, prosecutors have linked his death to the burning he suffered at 8. Prosecutors say his alleged attacker burned him to silence him about an alleged sexual assault. (Courtesy Middleton Family/AP)A Texas man who was horribly burned on most of his body at age 8 divulged a dark secret on his deathbed — the monster who set him ablaze had also raped him. Robbie Middleton died shortly after the videotaped admission last year, and now prosecutors hope to use his tortured words to go after a convicted sex offender who had abused another boy. “It was done to prevent Middleton from talking,” Montgomery County attorney David Walker told the Houston Chronicle about the atrocious acts 14 years ago. Middleton gave the 27-minute statement to name his alleged attacker again and confess he was raped by him two weeks before he was set on fire, Walker said.
