KENT COUNTY, Mich. (WZZM) - The Kent County Sheriff Department is asking the public for help in locating a missing 16 year old. Investigators say Joanna Renee Henry left her Cannon Twp. home on August 7, between 3:45 p.m. and 5:41 p.m.
They say Henry has run away before, but has never been gone this long. Investigators do not believe foul play is involved, but say the teen suffers from bi-polar/depression and is possibly without her medication.
Joanna is described as a white female, 5'10", 190 pounds, medium length blond hair, hazel eyes, a tattoo of "Faith" on the left side of her rib cage, and a tattoo of a cross on her right pinky.
