An 18-year-old California resident charged with sexually assaulting two boys told police he molested as many as 50 children in different cities over the past eight years, police said. Joseph Hayden Boston was arrested Saturday after he allegedly confessed to his mother that he’d molested two boys, aged 8 and 4, at a motel just hours earlier, according to a police statement. “Officers interviewed the suspect and he confessed to sexually assaulting the two juvenile victims in his motel room. He also admitted to molesting upward of 50 children since he was 10 years old in different cities where he had lived,” Riverside Police Department spokesman Ryan Railsback said. The County of Riverside Child Protective Services took the two recent victims into custody and police are investigating other claims of abuse.
