A 2-month-old girl whose death was used by critics as an example of endangered children on the Spirit Lake Reservation died of natural causes.
U.S. Attorney Tim Purdon tells The Forum newspaper (http://bit.ly/SyEn5E ) that Debra Kay Andersen Dogskin's July 7 death at her mother's home in St. Michael was sudden infant death syndrome. Purdon says the state medical examiner determined the cause of death, and federal prosecutors decided against filing charges.
Purdon says the investigation took almost five months because officials wanted to be sure their review was thorough.
The federal Bureau of Indian Affairs assumed control of the North Dakota tribe's social service program in October after criticism that the tribe has failed to protect vulnerable children.
