Apologies; I wasn't referring to the police, rather the press who apparently took Mr Riglin along for a jolly. I expect he made up all sorts of things for their benefit. But this isn't evidence. This is entertainment. Evidence is what you sign in front of a police officer.
DV asserts the police must have used the front door key to gain entry as the door appeared to show no sign of damage. He misleads by making leading assertions, does the thinking for others and puts words into their mouths then classifies it all as factual evidence when it's nothing of the kind. Leaving aside the precise particulars as to whether the door would necessarily have shown signs of damage (which is debateable anyway), why would you use a key to get in to search and then go on to assert that in fact you didn't use a key to get in and moreover, that it had gone missing along with SL? It's an absurdity. The police lifted a window, used a back door key or forced their way in somehow and did so that first evening when the estate agency was shut. There's zero record from what I've seen, of the office being opened to hand over a front door key. They could have used a back door key possibly had the agency held one.
As to staff covering up. Why would they potentially expose themselves to a charge of perverting the course of justice? This is a colleague who'd gone missing. You just wouldn't do that, particularly in a pending, potential murder inquiry.
This whole Shorrolds Rd key saga is a red herring. When they eventually caught JC and found various keys in his possession, did the police ever check for the one missing from Shorrolds Road? They worked out a couple, but others were never traced back to a door and JC kept schtum (Berry-Dee). Were these trophies linked to some past, memorable events like the hotel room key used for a dirty weekend with his ice dancer?
