A Washington state father has been arrested in connection with the death of his 4-year-old son, whose remains were discovered buried beneath the family home approximately one year after the alleged killing.

According to reports, the father admitted to striking the child on the head, resulting in the boy's death. The body was subsequently buried under the house where it remained undiscovered for about a year.

The circumstances that led to the discovery of the remains have not been detailed in available reports. The case appears to involve a significant delay between the alleged crime and the recovery of the child's body.

Authorities have not released additional details about the investigation, including the specific charges filed against the father or the timeline of events leading up to the arrest. The identity of the suspect and victim have not been publicly disclosed.

The case highlights ongoing concerns about child welfare and domestic violence within family settings. Local law enforcement agencies are expected to provide additional information as the investigation continues.
