The owners of the Boulder house where JonBenet Ramsey was killed told documentary producers to take a hike when they literally tried to return to the scene of the crime.
Carol Schuller Milner and her husband currently live in the home, and she tells TMZ ... a production company contacted them months ago asking to lease their house. She says they immediately turned them down ... saying they had NO interest in dredging up horrific memories.
If you saw CBS' special, "The Case of: JonBenet Ramsey" ... you noticed producers had to build replica rooms, because they had zero access to the real deal.
Even if the Milners had played ball ... Carol says they made major renovations 10 years ago, which included the basement. She says it wasn't because they were creeped out -- they'd already been there for 2 years -- it was just time for a makeover.
