Law enforcement has never made any statements of the whereabouts of the dogs. As near as I can figure it, the statement that the dogs were found in the basement comes from a social media post or comment.If the dogs were in the basement, and typically kept there when everyone was out, wouldn't that support the point that she did not return home from her run?
When police arrived at the house-sit home, did they find the dogs in the basement? Was that typically where they were left when no one was home? As a house-sit, Mollie would not have left the dogs in the basement if she was at home.
If the dogs were still in the basement, doesn't that mean that Mollie did not arrive home from her run? It is described as an "abduction". If so, from where?
I am highly confident, though law enforcement hasn't said, that one or several people had been to or even went into the home Mollie was staying at prior to Mollie being reported missing. Especially considering she wasn't reported missing until 5:56pm and her brother, mother, boyfriend, (and probably others they contacted) knew Mollie hadn't showed up at work and they had been unable to contact her hours before 5:56pm. Thus, I expect the scene at the house (if it is relevant) to be compromised.
I suppose it is possible, despite the less than a mile proximity for many relatives of Mollie or Mollie's boyfriend or his brother's fiance's family, that no one went over to check and/or none of them had a key to enter and the police were the first to go in there but I doubt that highly.
