My fellow colleagues,

As you may or may not be aware, I employ unorthodox investigation and interrogation techniques and an unusual assortment of gear with which are often mired in controversy. I pay little heed to those who doubt my investigative methods however and roll with what works for me based on my extensive experience in the field.

For the better part of the day I have been mulling over the existing story and evidence provided so far while contemplating the best course of action to take next. I have turned to my trustworthy Gibson SG-62 as a primary investigative tool to determine the correct path as it was the obvious choice to move forward given the evidence so far. After 8 hours of deliberation with free-style cross-genre rhythm and lead improvisation with a few necessary bio-breaks have lead to a chord progression which I believe is highly suggestive of the next course of action, as well as certain solo elements which have highlighted certain elements of the details so far.

Some observations from the jam session:
- The camouflaged shooter appeared from behind a rock presumably at close range, shot Markus once in the leg and then turned and headed off into the woods. This suggests to me that the shooter either had very poor aim and/or simply did not really intend to kill him. Perhaps they meant only to wound him with a knee shot to send a message, or perhaps they just wanted him to be scared into dropping the mafia expose. However, if it were merely a scare tactic then Lynnette probably would not have been killed also. She was killed point blank, but Markus in the knee?

- Lynnette may be the one who turned off the alarm. One reason why one might do this is because they know the person on the other side of the door. My guitar suggests to me that Lynnette looked through the peephole and saw a familiar unmasked face, disabled the alarm and opened the door where she was shot at point blank from the familiar face, whom then put their mask back on prior to Leroy seeing them.

- The gun was found near Markus' body, which suggests to me that if this was a single assailant with a single weapon, then either Markus was killed last and the weapon ditched not far away from his body, or Markus was as Zeagold suggests killed first, then the killer returned after killing Lynnette to Markus' body where they left the gun behind.

- Since the mask etc. were found in a shed near the house, it would seem that the wife was first killed, then Markus, then the killer went back near the house to leave the gloves. That seems very odd. If they threw the gun down, why would they not keep their mask etc. until they were far enough away and then ditch them in the woods or elsewhere instead? Something smells very fishy. Seems like a dangerous extra effort to go back near the house to remove a mask then walk away unmasked. Why wear the mask in the first place if you're going to expose yourself like this to others who may be in the house?

- The mafia would not put out a hit on someone and send a hitman with poor aim like that. Markus could have potentially survived the knee shot. The killer suddenly appeared from behind a rock suggests they were waiting there to ambush Markus because it would seem unlikely that they would have just stumbled upon him strolling unless they knew he was going to be filming there, in which case they could lay in ambush.

Considering all of these factors, my SG and I are of the opinion that the killer was known to Markus and Lynnette and that they were not sent by the mafia. A mafia hit man would have not only killed both of them, but would have killed the other two as well, as each person killed had another person near by as it happened who was observed by the killer who left them live. A mafia hit would have most likely taken out any additional witnesses to not leave any loose ends behind, and perhaps even made it look like they shot each other by planting weapons on them. The killer removing their mask near the house and placing it in the shed seems very careless as well, and if Markus was indeed killed first and they returned, why would they do so? To finish him off? A mafia hit would have done it the first time, not returned later to take another shot. I suspect the killer knew Markus and may have felt bad or guilty for killing him, and perhaps that is why their aim was off also.

- Why was the gun abandoned near Markus? Either out of carelessness due to emotion, or to purposefully be discovered, perhaps with fingerprints planted on it. Only a further investigation of the weapon might reveal that.

I believe the next step is to do a full crime scene investigation, as it is absolutely crucial that all evidence be discovered and considered as soon as possible after crimes like this. According to my guitar, if 24-48 hours goes by in these cases they often turn into cold cases never to be solved, so maximizing evidence is of key importance.

Therefore, I must vote for Crime Scene Search.
