When Amy, Jon Benet's dance classmate was assaulted by an intruder, Amy's mom said he reeked of cigarettes. Camel "blue" cigarette butts were found near the home. In the alley behind the Ramsey home, the same brand cigarette butts were found. Hence, IDI. The Ramsey intruder wore gloves, brought a pre-written ransom note and transcribed it onto Patsy's notepad, and faked a rough draft to make it appear it was freestyled, because it was part of the framing of the Ramseys. You RDI people fell for it.
