There was another part of her that suspected the involvement from someone else in the home that she had not met.
She had a gut feeling that the woman was not behind it after meeting with her in person.
It had been further proven that her gut feeling had been correct since the woman was being so cooperative.
It was not like Ash had identified herself as an investigator or private detective of any kind but it would make sense for anyone to deny such a request from a stranger or an investigator since it was their right.
There were cases where guilty parties denied such requests when there was no warrant involved giving them time to destroy any evidence but there were cases where they were very cooperative too since they believed that nothing could be found to incriminate them.
