"I'm just pondering what else could have happened," Cathy Wilson said. "If he's safe and he's away because he wants to be, that's fine. I just want to know that he's safe."
Family, friends and authorities described Wilson as an intense, scholarly student focused more on academics than on risky college behavior like drinking and drugs. His roommate, Elliot Harwell, told "Good Morning America" in December that he reported Wilson missing when the straight-A student failed to return to their dorm for three days in the run-up to semester finals.
"He is known for always attending classes and always getting good grades," Harwell said at the time. "He takes school seriously, but he didn't turn in his finals, so it is clear that he is behaving out of character."
Wilson is a white male, 5 feet 7 inches tall and weighing 135 pounds with red hair and green eyes. Wilson had a full beard when he was last seen, but is also known to be clean-shaven.
