Missing Michigan Woman Found Dead

By  | 

It could take up to four weeks to complete test results from an autopsy of a missing central Michigan found 14 months after her disappearance.

A forensic pathologist in Lansing is waiting for toxicology and other tests before concluding how Becky Sue MacDonald died.

Police found her body last Tuesday in a shallow grave in state forest land in Midland County's Edenville Township.

MacDonald was 42 when she vanished mid-November 2005.

Fingerprint results identified the body Friday.

Police are investigating a "person of interest" in the case.
