During the 38 days that Tad Cummins and 15-year-old Elizabeth Thomas were missing, as a massive manhunt spread from Tennessee across the country, the Tennessee Bureau of Investigation received more than 1,500 tips. But for five weeks, investigators came up empty. The 50-year-old teacher and the teenager he is accused of abducting were nowhere to be found. Late Wednesday night, the tip that TBI investigators were desperately hoping for finally arrived. It came from a caller who told investigators that Cummins and the teen, the subject of an Amber Alert, might be living in a mountain cabin near Cecilville, Calif., a onetime mining town about 100 miles south of the Oregon border. Tennessee investigators coordinated with the Siskiyou County Sheriff’s Office, which found the silver Nissan Rogue belonging to Cummins and kept the vehicle under surveillance for several hours in one of the northernmost parts of California. And then, at daybreak Thursday, the authorities captured Cummins and rescued the teen. Authorities said Elizabeth was physically unharmed, but her attorney said the teen has “suffered severe emotional trauma and that her process of recovery is just beginning,” according to the Associated Press. Anthony Thomas, the teen’s father, told “Good Morning America” on Friday that he thinks his daughter was brainwashed.
