(KAIR)--It's believed the cause of death for two 3-year-old Platte County children was accidental.

That word is delivered by the Platte County Sheriff's Office following the discovery Monday of the bodies of Arrabelle Wagner and Elijah Wagner.

The discovery followed the report late Monday morning by the father of the twins that they were missing from their South Ridgely Road residence.

Both were found in a pond behind the residence.

A press release from the Sheriff's Office says Elijah was pronounced dead at the scene while his sister was pronounced dead following her arrival at an area hospital.

According to The Kansas City Star, the residence is located south of Edgerton and west of Smithville Lake.

Platte County Undersheriff Major Erik Holland says the investigation is continuing, but the preliminary probe “points to an accidental death for both children.”
