A 15-year-old teenager with autism was pranked into doing the Ice Bucket Challenge. What happened next is disturbing.

The young man stripped down to his boxers, in anticipation of having a bucket of ice dumped on him to support ALS. Instead, a bucket of feces, urine, spit and cigarette butts was dumped on his head & the entire ordeal was caught on tape.

Local police are investigating to try and find the kids behind the prank. In addition, TV star Drew Carey is offering a $10,000 reward to find the culprits. He said he will donate all the money to Autism Speaks.
