What am I "wrong" about? I gather my information entirely from actual newspaper articles through the years with the Investigators, and also a poster from another forum, who is reliable, from the Gallup area, and her facts check out. You do know that you can respectfully disagree with me, without being rude. The person claiming to be Anthonette did not call her family, as you have stated. She was talking to a 9-1-1 dispatcher. While there is no conclusive proof or known convictions of the parents dealing drugs, from the fact that residents witnessed cars coming and going at all hours of the night at the house, and widespread rumors that they parents were involved in drugs, usually leads one to believe something shady is taking place at the residence. The fact that Penny passed away in her 40s could be the result of too many years of hard partying. Not certain, but it happens.
Finally, Wendy, the sibling in question, did not provide the information that she was a witness to Anthonette's alleged abduction to detectives, until several years later, so there was no way Investigators could have known an alleged abduction occurred that night, or what time it did occur at, until Wendy approached them. A far more credible lead from a neighbor, places a man in a car visiting the house sometime between 6:30-7 AM. Considering Law Enforcement believed Penny was somehow involved in her daughters disappearance, there is an excellent chance that Wendy was coached by her mother, about what to say to detectives, to possibly throw off suspicion.
At any rate, you seem to be going by the Unsolved Mysteries episode from 25 years ago. The problem with Unsolved Mysteries, is in order to appeal to a larger demographic (TV Ratings), they had the habit of glossing over certain facts/lifestyle choices/etc. By nature, people seem to be more sympathetic to well dressed, wholesome mother, than they would be if the rumors about drugs and partying at all hours of the night were true. There is also the unexplained purchase of a new car, and the mother Penny failing the polygraph test, that Unsolved Mysteries left out.
