http://miscarriageofjustice.co/index.php?topic=296.0Page 11 has the police telling Bamber that Julie knew about the lockable from outside window.
Obviously the relatives told Julie about this window as Bamber told the police he wasn't aware of such a window. Bit strange that Bamber then said he 'didn't think' he had told Julie about this window.
The relatives had very limited opportunities in which to tell Julie about the lockable from outside window. Julie was with Bamber 99% of the time, usually out of Essex. The other 1% of the time Julie was with friends such as Susan Battersby.
The relatives also didn't find out about the lockable from outside window until a long time after the massacre. So had a short time scale to get in touch with Julie.
In the 4 weeks before Julie approached the police, when did the relatives tell Julie about the lockable from outside window ?
