That’s how Nightline described Jon Benet Ramsey (screw you, Lindbergh baby) at the top of last night’s broadcast, the majority of which was devoted to the shocking new arrest in the 10-year-old Jon Benet murder investigation.

There is so much new, iffy, and contradictory information about the arrest—more seems to arrive every minute—that it’s hard to know what’s what. For a good general overview, try this Associated Press report.

Among the freakish details being reported in the wake of the arrest of John Mark Karr, the 41-year-old American ex-school teacher and ex-con with an extensive criminal record of sexual assaults and possession of child pornography:

*Karr has linked himself to the murder. “I was with JonBenet when she died,” Karr told AP reporters after his arrest. “Her death was an accident.” Asked to describe what happened when JonBenet died, Karr said: “It would take several hours to describe that. It’s a very involved series of events that would involve a lot of time. It’s very painful for me to talk about it.” (Thai authorities confirm that Karr confessed to being with Jon Benet when she died, during a “kidnapping attempt gone wrong.”)

*However, Karr’s ex-wife has provided her ex-husband with an alibi, announcing she was with Karr in Alabama at the time of JonBenet’s death (Christmas Day, 1996).

*Meanwhile, Karr’s family members have weighed in with testimony about Karr’s obsession with the cases of Jon Benet and Polly Klaas and his ongoing research for a book about the Jon Benet murder. (For an interview with Karr’s fascinatingly befuddled father, go here.)

As John Karr is transported to Colorado, where he will face charges of first-degree murder, kidnapping and child sexual assault, questions abound: Could this really be a false confession, by either a mentally unstable man with a child-murder obsession or a mentally unstable author-to-be looking for the ultimate scoop? (If so, how did Karr know what the Ramsey family’s attorney described as “information about the murder that has never been publicly disclosed”?) What’s up with the ex-wife’s alibi? And did John and Patsy Ramsey really suffer through all that horrible suspicion about their involvement for nothing?

Stay tuned for answers. In the meantime, familiarize yourself with the face of John Karr, who used to look kinda normal but at the time of his arrest looked emaciated and insane.
