As it is, if this was a dead male in exactly the same circumstances (granted statistically very unlikely) I'd be saying the same thing.
Statistically if it is natural causes then no it would be equally likely
Now some forces may do it slightly differently but it usually goes something like this;
If you are following PACE or another set of rules it should be exactly the same.
Before questioning him regarding this (by arrest or voluntarily) we are likely to conduct telecoms enquiries to see if we can locate the IP address for where the profiles were created so we have some evidence to put to the suspect.
When I was being questioned, after I was arrested for something that didn't happen. Ie I was on one continent and was supposed to use a computer on a different continent to send an email in the UK (third continent) I suggested to the officer who had arrested me that he check the IP address, he asked me, "what's an IP address?"
They then threatened to take every computer my employer had. Remember the allegation was about me using a specific computer and I had not had access to my employer's computers because I wasn't in Europe when the e-mail was sent.
He had already taken my PC, including monitor, mouse and printer, I asked why they needed a printer and he said, "My mate says there is memory in it" By that time I didn't bother asking about the mouse.
His chief constable has continued to back him up as I was apparently a, 'credible suspect'
Oh, almost forgot, when they were returning the PC to me at a set time they 'got lost' on the way. Now if I lived in a far flung place I could understand that but if I was to give you the instructions from the police station to my home it would be:
Turn right as you come out of the station
follow the same road until you see McDonald's
At the roundabout after McDonald's take second left
take 1st leaft
take 2nd left
Knock on the door
Strangely all the CCTV in that police station were broken and not recording that day, all of them. The same police force who had splashed their new high tech monitoring / CCTV "best in the UK" all over the local paper.
Oh and before I was even interviewed I was told, "if you accept a caution you can go home now"
Rod is a fucking tit.
Rod is a typical officer. If you question anything it's because you don't understand procedure. Lazy, follows PACE when it suits and goes for the easy option.
