Since you brought up another case within this thread, how about the following for "entertainment"? In April of 2008 I began documenting the reverse speech that I found on a guy named Sam Parker who was a suspect in the disappearance of his wife Theresa. His reverse speech clearly indicated that he had killed her. His reversals also indicated motive. On September 3, 2009 he was convicted by a jury of murdering his wife. This validates the accuracy of reverse speech I found. Testimony from the trial also validated other reversals I found on Sam Parker. Link to page:
Theresa Parker
There are several other aspects of other cases posted on my site that I've been following that are proving the reverse speech examples I have found to be accurate.
Now back to this case, for more "entertainment". I began posting my findings on my website about this case on March 19, 2009. Based solely on the speech reversals I found from the 911 call, it appeared Ron and Misty were not a part of Haleigh's disappearance, nor did they appear to know who took her.
On August 18, 2009 police declared Ron was cleared as a suspect. That would be 5 mos. after my findings were made public. Once again I would say that would validate the accuracy of the reversals.
I now have several different interviews with Misty that contain examples of her reverse speech. Non of them indicate she knows what has happened, how it happened, or who (with certainty) is involved. Again, her reversals have indicated why she believes her cousin "Joe" is involved.
A final thought regarding Casey Anthony. Non of her reversals indicate she was directly involved in killing her daughter. Non of her reversals indicate motive. They do indicate she is scared, and that at least one other male is involved.
