A Black Indiana teen faces serious jail time for what he says was a senior prank that was taken much more seriously by local authorities.

According to the Indianapolis Star newspaper, Tyell Morton placed a blow-up sex doll in a girls’ bathroom stall early on the morning of May 31 as a senior prank at his school in Rushville, Ind. But a janitor spotted him exiting the school wearing gloves and a hooded sweatshirt that covered his face, leading school officials to fear that a mysterious intruder had planted explosives in the building.

Shortly thereafter, Indiana’s Rushville Consolidated High School was locked down for three hours and police units and K-9 dogs explored the building in a fruitless search of explosives. The youth was arrested later that day and spent five days in jail. He was released on $36,000 bond.

Morton was charged with disorderly conduct, a misdemeanor, and institutional criminal mischief, a felony. If convicted, the 18-year-old could be sentenced to up to eight years in prison.

โ€œI know there has been plenty of pranks done at that school,โ€ Cammie Morton, the teen’s mother told the Indianapolis Star. โ€œI went to that school. When I heard what they was charging him for, my heart just dropped.โ€

Protesters say school administrators and police overreacted with charges that are unreasonably harsh, citing race as the motivating factor. โ€œSchools and law enforcement are taking `zero-toleranceโ€™ policies too far,โ€ said a page on Change.org, a self-styled โ€œactivism platform for social change.โ€

โ€œ This is an 18 -year old kid who has never been in any kind of trouble before, facing prison time for a prank. He was held in jail with a $30,000 bond and not allowed to graduate. We do not believe, in this case, that the punishment fits the crime,โ€ Change.org said. Another Web site, FreeTyellMorton.org, was recently created, providing an arena for supporters to contribute, through PayPal, to a defense fund for him.

The teen wasnโ€™t allowed to participate in his schoolโ€™s graduation, but received his diploma in the mail.

โ€œIt’s not right. It was a senior prank. They’re blowing it out of proportion. I didn’t hurt anybody, I didn’t intend to embarrass anybody. What did I do wrong, you know?โ€ Morton told NBC Indianapolis affiliate WTHR.

But nonetheless, administrators and officials are standing by the charges, saying the prank cost the school $8,000.

โ€œIn this post-Columbine world, that’s what you get when these kinds of things happen,โ€ Rush County prosecutor Phil Caviness told WTHR.

Morton’s trial is set for Sept. 13 in Rush Circuit Court.
