I read this morning that both Kellie Pratt and Natalie Pearman both drank in the pub (The Ferry Boat Inn) where Mr Wright was the landlord for 5 months. Both were prostitues and both dies of strangulation.
The media is grabbing tiny bits of evidence and throwing them around to sell papers, the sources are often not incredibly credible, but this seems to be a huge coincidence.
I'm sure the police are looking into every possibility, but they are probabaly trying to keep it quiet for many reasons, we must remember also that the guilty party will have to stand trial, the more nitty gritty speculation that gets thrown about could affect a "fair" trial. Who on earth in England at the moment has not formed an opinion of the person who did this as a result of the press coverage. It's a bit of a catch 22. They need the public to help, but additionally they don't want them knowing too much.
