Yes, they did have samples of Burke's handwriting.Here's what I think FWIW. I agree that it would be very unusual to cover up an accident to make it look like murder. There is too much chance that those doing the coverup could be accused of murder (as the Ramseys were by the public). If either parent had only found JBR unconscious from the head blow, I think they would have called 911 immediately, hoping to save her, and said it was a terrible accident. No one could prove it wasn't. The fact that they covered up tells me that it was clear that she had also been strangled with the garotte, so they knew she was dead and that it wasn't an accident. At that point the coverup to save Burke commenced. While the initial blow to JBR's head may have been an accident, the garotte makes it clear to me that this was not an accident at least from that point on. I really don't see either JR or PR using the garotte in a coverup, especially using part of PR's paintbrush.
Another thought to add...I know it's pretty universally accepted that Patsy wrote the ransom letter. Did anyone ever get handwriting samples from Burke? I really don't think it's beyond the ability of a bright and probably linguistically precocious 10 year old to write. He may have even seen the movies some of the expressions came from. Writing a ransom note seems more like something a ten year old would do than Patsy attempting a coverup. I realize the CBS show considered Patsy the writer and I'm probably defying logic, but I just wonder.
I found a good deal of information in "The Bonita Papers". Go to Google and type that in.
It's rather lengthy but the layout
and the way it reads is much better than most of the books I've read. And it is very informative.
