The episode of Ghost Hunters featuring their investigation of the Missouri State Penitentiary is supposed to air this fall sometime.
The new season of Ghost Hunters premieres in August on the SyFy channel.
A big announcement was made at Sunday night TMs Mystery Party at the Missouri State Penitentiary.
The national hit television show Ghost Hunters will investigate the famous facility.
Ghost Hunters is an American paranormal reality television series on the SyFy channel.
The two investigators, Jason Hawes and Grant Wilson are the leaders of taps, The Atlantic Paranormal Society.
The Jefferson City convention and visitors bureau was contacted by the show in January and just last week Ghost Hunters conducted their investigation at MSP.
"Millions of people watch their show every week, we were just so excited to have the chance to publicize this gem that we have in Jefferson City to the nation," Jefferson City Conventions and Visitors Bureau communications manager Sarah Alsager said.
Two of MSP's tour guides shared told the investigators about the prison's history and about different infamous inmates who spent time there.
"They were in aw of the Missouri State Penitentiary, Alsager said. They thought it was so cool, they have been to other historic prisons, but they had never seen one as massive as ours."
Before it closed the Missouri State Penitentiary was the oldest continually operating penitentiary west of the Mississippi.
And was also infamously named the bloodiest 47 acres in America by time magazine because of the number of assaults on the grounds between 1963 and 1964.
This weekend the Missouri State Penitentiary is celebrated its 175th anniversary.
An air date for taps visit to MSP hasn't been determined yet.
