Sandra Wesley made a declaration I can't understand regarding this. She said the MP would not call LE in a circumstance like that because they would most probably be closed and prosecuted for pimping.
This is an interesting question but I have not read whether the MP called the police or not. I would presume if it was done on an outcall basis they would have known and gotten a piece of the booking. Assuming the booking was done with the MP, the lady would have typically called when the appointment was done, and if she did not call, I would see no problem in calling the police. After all, how would the police know what service the client was paying for, it could have been a back rub and companionship for all they know, so I am confused by Wesley's comment.
It is also not clear what good calling the police would have done, unless the MP got a distress call of some kind from the lady. She was found dead after the perp confessed to police and told them where to find the body.
In cases like this if there is some disturbance it is the hotel's security force that is responsible for the security of guests, so a question would be whether any guests reported any noise to security, although this is kind of a moot issue as far as investigating the crime because the perp has confessed, but maybe an active issue as far as a negligent security lawsuit or insurance claim against the hotel. There was a murder of a guest at a Connecticut hotel around 12 years ago and the hotel ended up paying to settle that case:
