They lived in the same foster home in Logan, Iowa. Now, a five-year-old boy is dead, and a teenager is accused of his murder.

17-year-old Cody Metzger-Madsen is under arrest, charged in the death of five-year-old Dominic Elkins. His body was found in a ravine near over the weekend.

Investigators say Dominic had been in the home for only a few weeks. An autopsy has been completed, but the Iowa medical examiner is conducting further lab tests. A definitive cause of death should be ready later today.
