MADISONVILLE, Tenn. – A senior prank gone wrong resulted in a school resource officer losing his job, a principal on unpaid suspension, and 100 students who can no longer participate in their graduation ceremony.

Police told WIBW about 100 students ransacked Sequoyah High School last Thursday as a senior prank with help from the school’s resource officer, James Fisher, and tacit approval by principal Gary Cole.

Around midnight April 30, Fisher unlocked the back doors to the school gym and allowed students to enter with the understanding not to steal or damage property. Two waves of students participated in the prank, the first showering hallways with glitter, balloons, toilet paper and fishing wire.

“The first wave, wasn’t bad, just simple pranks that did no harm,” senior Kody Hampton told the news site.

Around 1 p.m., a second wave of students took the prank to the extreme.

They dumped out garbage cans and strewed the contents, urinated in the school, spread ketchup and baby oil on the walls, released crickets and chickens, dumped gold fish in toilets, cast hay down the hallways and even left a dead opossum behind, the New York Daily News reports.

Some also booby trapped doorways with marbles, leading to three worker’s compensation claims filed by teachers afterwards. Students also reported items missing from their lockers the next day.

“I walked out of the building, I looked at the camera and said ‘I was not part of this,’ it was awful,” senior Kody Hampton told WVLT. “It was awful.”

During the melee, two officers from nearby Madisonville stopped in, but did nothing to halt the vandalism.

Fisher, who helped the first wave haul in their supplies, did not return to the school until he got word things were out of control. By then, it was too late.

He allegedly lied about his involvement, and was later fired by Monroe County Sheriff Tommy Jones, WIBW reports.

“I am sorry to announce that I had to terminate Deputy James Fisher who has served in the capacity of SRO at Sequoyah High School for Official Misconduct. When the incident was first reported Deputy Fisher gave Director Tim Blankenship and myself a false report about what happened,” Jones said in a statement.

“We reviewed the schools security video and when I spoke Deputy Fisher a second time he admitted to the false statement. … The video shows him opening up the school helping the students carry items in and later leaving while the kids were still in the building. He then returns after receiving a call that the prank has gotten out of hand.”

District officials also released a statement when they suspended principal Gary Cole.

“After receiving additional details concerning the events that took place at Sequoyah High School on April 30, 2015, Director of Schools Tim Blankenship has suspended Principal Gary Cole indefinitely, pending an investigation. This suspension is without pay. Any further decision will be made when the investigation is concluded,” the statement read.

Cole is now under investigation by the Tennessee Bureau of Investigation for his role in the prank, though he has already resigned to take a teaching position at North Alabama University, according to the Knoxville News Sentinel.

School officials also banned the roughly 100 students involved in the prank from participating in graduation activities, including their graduation ceremony.

Senior Shania Woods told WVLT she doesn’t think it’s fair that all students who participated in the stunt should be punished equally, since many were not involved with the serious damage.

“Peeing on the walls is a disgrace, and it was not my fault,” she said. “I’m not gonna take charge for what someone else did.”
