According to this article (and Charley Project): In 1993, Stratton started receiving threatening phone calls at home, which lasted for two years. The callers would often demand money in exchange for Ledkins.
Stratton recorded the calls and sent them to the police. Investigators traced the calls back to a pay phone in the Kansas City area, but no one was ever identified as the caller.
In this transcript, the caller said, "If we don't get the money, your daughter will be sent to you in pieces."
This seems odd. Why would anyone kidnap a girl for ransom whose "home life in 1985 was dysfunctional", living in not the best neighborhood in the city, from a single mom who probably doesn't have money for ransom? It's not like she was the daughter of someone locally prestigious. Unless maybe she owed money for drugs or something?
Was the ransom amount ever mentioned?
Was it established who this "Lori" was that was mentioned by the caller? The mom seemed to know "Lori" so assuming it was a relative or friend.
Could Lori have been in on it and that's why the caller wanted to talk to her?
Did the mother ever try to offer the caller some money for the ransom?
Why did the caller stop calling after two years if the money was so important? Either they knew she was dead already or it was a sick hoax from opportunists that knew of Jody's disappearance from media. And obviously they never sent any "pieces" of Jody to the mother either. It would be safe to say if they were serious, they could have sent a finger or something as proof.
Perhaps the calls were even a guise to throw everyone off track.
Also, I'm not a handwriting analyst by any means, but I don't think the handwriting in the letters match. For example, in the letter to the probation officer received years after the disappearance, the capital "I" is written like a "J", dissimilar from the more cursive "I" in the letter to the mother. Investigators should have at least acquired handwriting samples from all those involved / "persons of interest" and see if anyone wrote the "I" like a "J". Perhaps they did and didn't reveal their findings?
