I think we're mostly getting it from the books, and I can't specify now which ones, it's been so long, that the Barnhills were silenced. I don't remember ever hearing that the walker went ACROSS THE LAWN, which certainly would connect the walker with the crime in my opinion! Anyone have a link for that? I'd been wondering if they actually saw him go in or if he was just walking by on the sidewalk, and always thought it's significant that he strongly resembled John Andrew.
It's kind of like the JFK case, imo, about which I caught part of one documentary last night, finally, on the History channel. One thing I caught this time that was new to me. A policeman who'd handcuffed Oswald to him to lead him out joked to LHO, "If someone shoots at you, I sure hope he's a better marksman than you." He said LHO said, "You're being melodramatic. Nobody's going to shoot at me." Evidently LHO had been told he wouldn't be convicted. And some of the books said there were at least 4 LHO's, lookalikes. So why would they shoot officer Tippett? Whichever one did, using Oswald's rifle he'd evidently delivered to the 6th floor by calling it a pkg of curtain rods?
This docu, titled "Beyond Conspiracy", had a bunch of men claiming to know LHO was an expert marksman, but years ago everyone said he wasn't. He'd had Marina take a picture of him with a rifle, obviously wanted for some reason to be thought of as a marksman. They didn't mention in this one that the back of JFK's head was blown off, and the traceotomy doctors used what they felt was an entrance wound in the front of his throat. So it seemed it was all just another whitewash attempt. One woman at the end said she still feels LHO was a CIA agent. I wonder how long she'll be alive and well? So many of the original witnesses died within a decade, according to at least one of the books, probably Sybil Lee's, or Mark Lane's.
But back to JonBenet, I don't think she was feeling well on her last day, and a lot of previous days. I too often wonder about the school nurse.
That really SEEMS to fit in with the Barnhills apparently being silenced, and even the Stanton's about what they heard.
