LOGAN, Iowa (AP) — The cause of death of a 5-year-old boy found in a western Iowa ravine has not yet been released. An autopsy on the boy’s body was completed today (Monday), but the Iowa medical examiner’s office is conducting further laboratory tests before a definitive cause is released. Dominic Lloyd Lee Elkins, who was found dead Saturday in rural Harrison County, had lived with a foster family near Logan for nearly three weeks. 17-year-old Cody Metzker-Madsen, who lived in the same foster home for nearly three years, has been charged with first-degree murder in the 5-year-old’s death.
