Shannon Bell is a character in Cannibal! The Musical, which is based on the story of Alferd Packer.
In Cannibal!, Bell is portrayed as a Mormon preacher with an increasingly pessimistic outlook. He finally reaches his breaking point when Israel Swan sings "Let's Build A Snowman", and shoots Swan. The rest of the mining party eats Swan's body to stay alive. Eventually, Bell kills the rest of the miners, minus Packer, and decides to eat them as well. Packer supposedly kills Bell in self-defense and is later blamed for Bell's crimes.
Bell makes one final appearance near the end of the film in a jump scare.
