One needs a keen sense of the ridiculous when digesting the content of this thread.
A bunch of professional intelligentsia, as we are oft advised by a few posters, allegedly trained to act decisively and think lucidly in emergencies:
One delegates the task of phoning the police to another and/or there is a chat about who should make a call or indeed if a call should be made and to whom. It is not quite clear and no one really seems to know what happened with any degree of certainty.
We are led to believe none of them knew the emergency phone number !
The time of the first phone call, alleged to be before 10:41, was not known or recorded by either the OC or the mobile phone from which the call was made, whichever.
The police recorded the incorrect time because they were incompetent or, even at such early doors, were already involved in a conspiracy of events before they even knew what the event was.
All the protagonists reacted in the same way, panic!. Nary a one was of the type who in an emergency has a hyper-arousal of the senses and thinks lucidly and acts accordingly?
I guess in the absence of anything else reasonable, one would be inclined to believe 10:41.
