I've heard those claims before, and they don't always turn out to be true. To me, that is not "beyond a reasonable doubt" type of evidence. Pankey wasn't a neighbor. He lived there in Greeley. The neighbor I'm talking about is Norris Drake.
They investigated Drake and concluded he had nothing to do with the case. The defense just threw that accusation out there about him liking young girls, with no evidence of that. Common tactic in a murder case.
Pankeys wife of 25 years had important testimony, imo. I believed her about his desperate attempt for an alibi---they had no plans to go to California for Christmas. He refused his parents invitation. But on the morning after she went missing, Pankey came home in a rush and demanded she pack up the kids for a drive to California for Christmas.
She asked how they could get ready so quickly and who'd watch their two Great Danes. HE DUMPED THE FAMILY DOGS in the woods and deserted them so they could leave in a hurry.
When they got to California no one knew they were coming and it was an awkward trip. They didn't bring gifts or anything and the kids were cranky. Pankey got in a big argument with his father so the family drove back to Greeley after 4 days or so.
Incidentally, Pankey used that trip to California as his alibi when police eventually questioned him.
On the long drive back to Colorado, Pankey made his wife keep searching the car radio stations for news reports about the missing girl. She said that was highly unusual as he never listened to news radio in the car before. She said he demanded that she continuously search the dials for new news reports on the radio for the entire drive home.
She also said that he inexplicably set the family car on fire, from the inside. He lit it up in their backyard in the middle of the night. He gave no explanation and she was afraid to keep asking.
She also found ripped up yellow legal pad papers with his hand written notes, all about his thoughts about Jonelle's kidnapping. He wrote about the raking in the snow to cover the footprints.
These notes she found were written BEFORE he was spoken to by the detectives. So he did not learn about that info from them.
His wife wrote all of this info down, and kept those notes from the waste basket, and called Ketchum police, which was her local PD. She spoke to a detective there for 45 minutes and he promised he would call Greeley detectives to send them her evidence. She dropped it off to them. [she had no car to get to Greely]
Ketchum police apparently never made that call. She never heard from Greeley PD until 19 years later I believe. She had already divorced Pankey and had a protective order but was afraid of him so she never followed up on it again herself.
[this was all in an interview with her, from 'The Girl On The Milk Carton' on Oxygen network last night. It was a 3 part documentary---very well done]
