Tyler Campbell, the 19-year-old who was reported missing in Lincoln County over the weekend, has been found alive. He was found Tuesday afternoon off Interstate 65 North, just south of the Tennessee line. He is okay. Lincoln County Sheriff Murray Blackwelder said Campbell ran off the road in his truck Saturday night. He went down a ravine and got stuck there for three days. Campbell was just able to get up the ravine today, and climbed up, crawled under a guardrail and flagged down a passing driver. Paramedics took him to Huntsville Hospital for treatment.
