What was Murray trying to hide the morning of June 25th?

Okay, so everyday the acts of June 25 seem more and more like a well organized set up.

Today we found out about the voice mail Dr.Murray left for a patient at 11:54AM.
In the call he sounds completely calm with no sign of distress what-so-ever.

Then after this was leaked, Murray admits that he made up the entire time line of events from June 25, 2009.

Judging by the way Dr.Murray sounds in that voice mall, we can speculate that he isn't worried about anything. Which would mean that at 11:54AM Michael hasn't been discovered "unresponsive" yet.

Do you remember LaQuanda and LaQuisha? According to TMZ LaQuisha was at Dr.Murrays storage unit around 9:22 AM
Both sisters told completely different stories as to why LaQuisha was there. Looks like they didn't plan their stories ahead of time, giving the impression that they have something to hide.

Well if everything was fine at with Michael at 11:54am, then what could LaQuanda and LaQuisha possibly have to hide at 9:22am? At that time, Michael hasnt "Died" yet.
Maybe it's just part of the hoax set up...
