Claims to have been in communication with the dead are always so annoyingly vague aren't they?

"....She is also said to have said not to take things at face value regarding her murder and that he didn't act alone"

Why didn't she say something more along the lines of "there were two men, both white, one around six foot, the other shorter and more stocky, the shorter one called the other one 'Dennis'. I got a partial name for the other one, something like 'Dave', oh and at one point one of them called the other 'bruv'! I did glance out of the window and saw a car pull up, there was a third person in the car, remember a partial number plate something, something, something WOK."

Now that would be vastly more useful and compelling evidence, no?
