It all started with a birthday party for Randy Wagner's daughter.
After that, Randy decided to open it up for Halloween.
Today, Dr. Slaughter's House of Terror is an event that attracts thousands of people throughout the state.
"You know; if it wasn't for the community and the businesses in Idaho Falls, the sheriff's department and the police department we wouldn't be as big as we are now” said Randy.
Because of this growth, the Bonneville County and Idaho Falls D.A.R.E. program is benefitting tremendously.
"We’ve lost all the funding for the D.A.R.E. program through the state and through the school district and so right now the haunted house fully funds the entire program for Bonneville county and Idaho Falls" said Randy.
Every night volunteers get their faces painted. This is one of the tactics used to scare people.
"I go and I’ll get my costume and I’ll walk in the line and I’ll as their friend what their name is and then go and say their name and that scares them” said Addam Haskell.
"We get to walk through the lines and you know when we dance, during the dances there are parts of it where we get to run up and scare the crowd and it's a good feeling” said Joshua Hamberlin.
Dancers train hard to be able to perform every night.
All together there are about 150 kids who volunteer.
At Dr. Slaughter's House of Terror they have 20 dancers who practice all year round for a spectacular show.
Dr. Slaughter's House of Terror is located on W. Yellowstone Hwy. in Idaho Falls. It opens at 7:30 p.m. every night and closes at 10:00 p.m. except for weekends when it closes at midnight.
