Marlon Devine Santos, a 5-month-old baby, went missing on November 5, 1998. Marlon was in foster care with Yolanda and Jose Castillo when he disappeared. Yolanda left Marlon and two other foster children home alone, in an unlocked house, while she went to pick up her own children from school. When she returned, Marlon was gone. Yolanda waited over 48 hours before reporting him missing to the police. The police initially treated the case as an abduction or homicide and focused on the Castillos as suspects. However, no evidence was found, and the case remains unsolved. Jose Castillo was later charged with sexual assault of a foster child, but those are the only charges brought against him.
