I thought perhaps the wording meant "same bed", or "one bed" as opposed to them being in two beds.not disputing that, however it was a single bed which is a very cozy sleep. We can only speculate who was asleep and who was awake for now clearly X was awake but who else? I believe the wording was they were attacked in there sleep that does not necessarily mean they all didn't wake up during the attack.
I find it hard to believe that, writing up a probable cause document, an officer would make an irrelevant point about the size of a bed. Wouldn't that be like adding details about the paint color on the walls?
