Also whoever killed Joanna must have known that her boyfriend was not there and must have called at the flat. There are no reports from the police of signs of a struggle in the flat as far as I'm aware. If she had gone out somewhere she would have taken her mobile, keys and coat etc surely? Therefore it has to have been a neighbour, friend or someone she knew well enough or felt comfortable enough to go off with impromptu, probably thinking she would only be gone a short time. The strangest thing is that she left her keys behind - maybe because the person she went off with has keys to her flat?

As far as I'm concerned the Landlord is still in the frame, and the fact he has been released on police bail clearly means they are not prepared at this stage to completely eliminate him. However, I hope they are also investigating her other neighbours, friends, relatives and acquaintances.
