Cheers for you help lads. Will go the police on my way to work and report my conversation. Should I just leave it at then?
I have spent 3 years building my round up from doing it part-time to nearly a full round. I do not want one person destroying all my hard work.
I suggest you ask for some written proof that you have made the visit and why you have done it. I say this because as you are not actually reporting a crime, the person on the desk may be loathe to record it properly. Of course it is possible that she may be about to attempt an insurance scam - though it's unlikely they would pay her because they normally insist on "forced or violent entry" before paying. Leaving her door open wouldn't count as such - if indeed she did actually lose any jewellery at all.
If she really has been a victim of theft, I suppose it's possible to understand why she would be looking at anyone who was around about the time she noticed the items missing. I suppose it's also natural that she would look at any irregular visitors rather than invited guests/relatives. If she really believed you had done the deed, I believe she would have already reported this to the police. My hunch is that she suspects a friend/relative so has held back as she is unsure.
Of course, this assumes that a theft has taken place at all. Maybe she is trying to scam. Maybe she has alzheimers. Maybe she is mentally ill.
