CLEMSON — The Clemson University Police Department has a visual lead in the investigation of the Howard’s Rock vandalism from earlier this month.

Campus cops released a still photograph and two videos of a white pickup truck approaching and departing the scene on the east side of Memorial Stadium, with three individuals appearing to get out of the truck at 11:22 p.m. on Sunday, June 2 and returning at 11:33 p.m.

According to the incident report, police are investigating the time period between 4 p.m. on June 2 (when youth campers were taking pictures with Howard’s Rock) and 2:30 p.m. on June 3 (when university officials contacted police upon witnessing the damage.)

The university has announced a $5,000 reward for information leading to an arrest and conviction of vandals — money raised through private funding by the athletic department.

People with information on the case are asked to call CrimeStoppers at 1-888-CRIME-SC.

Howard’s Rock has stood above the hill overlooking Frank Howard Field for 47 years. Players and coaches traditionally rub the rock on their jaunt down the hill as part of pregame pagentry, a ritual which is expected to continue this fall even with 15 percent of the rock missing.
