I guess I can't do this alone. How about we all throw what we can think of this case and see where it leads us?

My thought so far

1. Markus fake his shot when he was recorded by camera. In video it shows he grabbed his lower leg left when shot with small patch of blood. This contradict with his autopsy report stated the wound is above leg, and since it hits artery, it won't be "small patch of blood". I believe it was orchestrated, adding that with giving false direction to Mike and then he had enough time to do whatever he want to do

2. Leroy is on phone for 20 minutes, his assistant on phone heard gunshot in the distance. I'm not sure if 2nd floor is enough distance to be called in the distance. Also, since he is on 2nd floor, he doesn't know if Lynette was in house or went outside before the time she got shot

3. A cloth to wipe gun tied in handle. Camo suite in a pot somewhere between Markus body and house, shows a cooperative work. The camo cloth might have been used by 2 persons

4. That empty shell in a ravine is confusing. That alarm, what does that mean? why it has to specifically mention the house is alarmed?

[edit]
forgot to vote for the note

The note holds the key! *tries his hand at conjuring up a new type of bagel*

I'm stumped. Mysterious Note

I would like to ask something. Whose bedroom it was where that mysterious note is found?

It was in the master bedroom. Lynette and Markus were staying in it.

I thought it was found in my pocket...? *paranoid time travelling confusion*

Well, I'm ASSUMING you were searching in the bedroom at the time.
At least, that's what the guys tell me.

i want to know what the mysterious note says too

I know,I know! It says Who gives a stuff!

Much to my surprise,
yes i thought about it twice
see it is our last clue
that will tell us what to do
error or not
red and hot
if we want to catch
or just about to fetch
us we shall prevail
so that we can hail

not the Mafia shall win
or the bad guys sin
the good guys, that is us
error is not good for us.

My vote

I TOLD you German poetry was horrible.

Did the sale got your mind wiped? That's no German!
And you dare to say horrible?

*hitting Zeogold with an gauntlet to initiate a duel*

Ups, sorry I meant to use the glove and not the gauntlet when hitting your head.

Apparently, this case is more than my pea brain can handle. I'm stumped. Maybe after I ponder it some more, something will make sense. My crazy theory flew out the window

Vote: Mysterious Note

It was written by a German.
Close enough.
You guys can discuss it with one another, y'know. Ask questions about theories, etc.

Are you sure? where is your prove?
Plus German is not only spoken in Germany :P
