Missing Mekenna Reiley, a 40-year-old Oregon speech teacher, was last seen in April disoriented and naked at a rural construction site according to her family, which suspects foul play and is asking for anyone who knows anything to speak with authorities.

Hours before she vanished, a work crew found her confused at their jobsite in Blue River, about 150 miles south of Portland, her sister, Bevin Stepp, who lives in Pennsylvania, told Fox News Digital.
