Circumstances of Disappearance

Jason was last seen at his apartment in the vicinity of the 100 block of Calhoun Street, in Clemson, SC. His vehicle was found at Table Rock State Park in Pickens, SC approximately 30 miles from his apartment. Despite an extensive search of the park area, Jason has not been located.

Knapp was a Clemson sophomore when he vanished just days after his induction into Clemson's elite Pershing Rifles. He was a mechanical engineering major. The day before he disappeared he and a friend had been looking for an apartment. That night he was at his apartment watching a movie. That's the last time his roommates saw him. Receipts found in his locked car at the state park show that he went to a Wendy's and stopped at an Ingles store for a six-pack of soda and a container of fruit juice on that Easter Sunday in 1998. His fingerprints were on a park admission ticket, showing he arrived between 3:00 p.m. - 5:00 p.m..

There is no evidence that he planned personal harm to himself. His personal rifle and some ammunition were found untouched in the closet of his bedroom. There is no evidence that he had planned to run away. According to an ATM receipt he had withdrawn only twenty (20) dollars from his bank account the day before his disappearance. Fifty (50) dollars in change was found in the console of his car. His checkbook was found in his apartment and contained a considerable amount of money, which had been untouched. His suitcase, all of his clothes and other personal belongings were still in the apartment.
