I wanna make something clear, it is right in front of you(Gal says it) so don't question it: Barns was the only one with no criminal record in the files. No matter what Disher or anyone else did, no matter whether mentioned or not, this is a fact.
Ninja, your theory about Gal killing the wrong victim is flawed. The killer did not wait for Lohan to return after killing the wrong person, walked away, Lohan chased him, so the killer did realise Lohan was still alive yet later on Barns was killed So no, Lohan was most likely not a target.
Last but not least, MO is method of operation, not place of operation, so the crossroad doesn't matter at all. Pay attention to the details. You did find the shooting being a different MO, though.
Just to help you move forward. I'll probably not be posting any further, only later on to set the deadline.
Okay so basically what u saying is that Disher did have a criminal record. Since barn is the only one without it so the motif of Gal is to kill people who had criminal records. But Barn was about to search the archives. Gal probably knew abt it and knew that if he searched the archives he would have found a clue. So he hoaxed him to his death. Starting to come along.
The MO's are : the first 2 killed people were killed using the same MO since they are civilians maybe? But since Marty before dying kinda tried to resist the killer and broke the blade. So he decided to change the method for not leaving any evidence by backstabbing his victim. But since he almost got caught with it he decided to shoot maybe? But i dont know where this will lead.
The blade was stolen, so if the killer wasnt within the office how would the killer have known where the blade is put? And since all the evidences with disher's death leads to the innocence of lohan, doson and haze. People who are left are Gal, Rollins and bricks. Bricks is barerly mentionned in the case. Rollins and Gal left.
UPDATE:
Just noticed something. While barns was looking for the archives of lohan knowing that he had a fight with the bar, the killer would have thought that if they find a criminal record on lohan they might heavy guard lohan thinking he is the next victim which would have made things a lot harder for the killer. So basically he killed Off.Barns.
Back to the MO. All 3 people with "criminal records" were killed using a knife. While Off barns was shot using a gun. The gun means that officer barns was probably armed unlike what Dt.haze said cz you know "bringing a knife to a gun fight" is kinda like suicide. So basically the killer probably knew that barns had a gun so he had to use Barn's gun to kill him he probably stole it in some way and killed him with it. And kept the gun to make it appear as if he was unarmed. Which leads us to Gal claiming to see barn's gun on the desk a fake claim.
Now in order for barns to let his guard down he must have seen somthing familiar, Someone he kinda trust aka Dt.Gal.
Back to Disher and Lohan. Andrew said that if the killer was targetting lohan in the first place his next victim would've been lohan. BUT as stated before if barns found the archives of lohan, Lohan may have been on heavy guarding. So thats why he had to Stop them searching the archives. And what better way than to kill the one in charge of the archives.
I think it's starting to come along.
