What do you mean 'unlike the others'? There is an address written down for the hospital, but so what anyway?
Why are the only calls listed for the whole of March 12 calls to a hospital and one to the business in Frinton? No calls to friends, relatives, employees for the whole of that period? Pull the other one!
Oh and Pam called June, not the other way around.
Provable by reference to the relevant metered call log, for the period 6pm Tuesday, 6th August 1985 to 8am, Wednesday, 7th August 1985, no less...
And for your information, the details posted relating to these metered calls were part of the original SC/688/85 file, at a time when police satisfied themselves that Sheila had shot and killed the others and then taken her own life, so you pull the other one...
