In Aberdeen, Washington, a 36-year-old man has been arrested in connection with the murder of his 4-year-old son, Aiden, whose remains were discovered buried in a relative's backyard. The arrest occurred after police responded to a missing child report on May 12 regarding the suspect's 6-year-old daughter, leading them to investigate Aiden's whereabouts. Initially, the father claimed Aiden was staying with a relative out-of-state, but further inquiries revealed this was false. Aiden's remains were found on May 15 at a property owned by his grandmother, where both she and the father resided. Aiden had previously been in foster care, and his former foster family expressed concerns about his safety, warning authorities that he was returned to an unsafe environment. They reported that Aiden frequently returned from visits with his biological family dirty and malnourished. The investigation into the events leading to Aiden's death continues, with police exploring the circumstances surrounding the boy's tragic fate.
