The other night I couldn't sleep and stayed up till all hours flipping channels. I've never been interested in crime cases, CSI or the law, until this case (Caylee stole my heart). So I have been watching programs on ID channel, and things like Forensic Files, Murder by the Book, etc.
The other night was an episode about a woman who had been receiving typed letters from a stalker and was eventually murdered. They suspected her husband, who tried to blame his step-son and others. A hand written letter was received by the police department claiming he was a serial killer and that her husband had NOT killed this woman, it was him.
They brought in a guy named Dr. Robert A. Leonard who they introduced as one of the founders of Sha Na Na, remember that group from the 70's that performed as if they still lived in the 50's? As a young child I was in LOVE with those guys so this episode really intrigued me.
He now has a PhD in Linguistics and was asked to come in and analyze the letters, both the batch of typed stalker letters which preceeded her murder, and the handwritten letter claiming the husband didn't do it.
What he noticed was something they said was very rare in both sets of letters, and GEE I wish I could remember what it was called. Ironic rhetoric? Or something. I remember an example: he'd say "She wanted to
break up with me so I
broke her neck, and he did this in several places in both sets of letters. Just brilliant deduction work in his analysis. They eventually confiscated the husband's computers and lo and behold - he'd been writing both sets of letters and of course, was the killer.
I wish Dr. Leonard would be interested enough to come and analyze this.
Edited to add video I just found of the episode I watched the other night
