Old X-rays have revealed that the badly decomposed body found on Coquille Indian tribal property is that of a 51-year-old woman last seen in August, Coos County investigators said. Leanne Darlene Boyer was reported missing by a friend after she failed to pick up her mail on Sept. 3, Chief Deputy District Attorney R. Paul Frasier said. Boyer is known to have spent a lot of time at transient camps in the area. Her body was found Oct. 6, about 20 yards from such a camp, in a brushy area by the north property line of the reservation, Frasier said. An autopsy failed to show a cause of death. Toxicology tests were sent to Portland and it could be several weeks before results are available. Forensics experts compared records of an old broken arm with X-rays taken from the remains to identify Boyer.
