Jason Andrew Knapp Missing From Table Rock State Park
Jason Andrew Knapp, age 20, was a college student living in the University Terrace Apartments at Clemson University in Clemson, South Carolina. He shared the apartment with a roommate. According to that roommate, Jason was last seen around 10 PM on April 11th, 1998, watching a movie.
Media coverage of Jason is extremely limited. Some sources say it wasn’t unusual for his roommate to go days without seeing him. Newspaper reports claim Jason was last seen at a fast‑food restaurant near campus. The Charley Project lists the roommate as the last confirmed witness.
Either way, the final confirmed date is the same: April 11th, 1998.
Jason was:
- 6'0", 150 lbs
- DOB: 12/30/1977
- last seen wearing a t‑shirt, blue jeans, blue sneakers, and possibly an Army ROTC hat and a watch
Abandoned Vehicle
Nine days after Jason was last seen, his car—a white 1990 Chevrolet Beretta, Pennsylvania plate APV9032—was found abandoned at Table Rock State Park.
Inside the vehicle, police found:
- a Wendy’s receipt dated April 11th
This matches the newspaper reports of Jason being seen at a fast‑food restaurant that day.
Based on the timeline, the car likely arrived at Table Rock on April 12th.
Between April 11th and April 21st, the region experienced extreme weather, including heavy rain and flooding. One report mentions a washed‑out bridge. Search teams combed the area extensively, but no trace of Jason was found.
Confirmed Fingerprint
In 1999, the FBI released a key detail: Jason’s fingerprint was found on a parking stub dated April 11th, 1998 at 3:30 PM.
This confirms:
- Jason was in the vehicle
- Jason was alive and active on April 11th
- Jason himself drove or handled the car that day
This is the only confirmed physical evidence ever recovered in the case.
The FBI reportedly conducted a thorough forensic examination of the vehicle and Jason’s possessions. Nothing else pointed to foul play, mental health issues, or voluntary disappearance.
Vanished.us Says
This case is one of those maddeningly sparse ones.
Jason leaves campus. He buys food. He drives to Table Rock State Park. Then he vanishes.
The extreme weather between April 11th and April 21st complicates everything. If Jason went hiking—intentionally or impulsively—conditions could have turned deadly fast. Flooded trails, washed‑out bridges, unstable ground, and poor visibility can erase tracks and conceal remains.
Given:
- No signs of mental health issues
- No evidence of foul play
- No suspicious activity in the vehicle
- The weather conditions
- And the location
The simplest explanation is that Jason went for a hike and suffered an accident.
But the lack of any recovered items—no clothing, no gear, no remains—keeps the case open and unsettling.
