Alpena, MI — Authorities have discovered the body of a missing teenager buried behind a home in Alpena County. Brynn Bills of Alpena was last seen by her family early in August. A tip led police to a home in Alpena Township where her remains were found Tuesday in dirt that had been recently disturbed. Bills would have turned 18 on Aug. 12. State police arrested the owner of the home for an unrelated matter and described him as a “person of interest” in Bills’ death. First Lt. John Grimshaw says some details can't be made public while the investigation is ongoing.
