I think it could easily be swept under the rug.  You've got 2 witnesses (Castle and Beckett) and 2 other detectives vouching for their stories.  There would be nothing to investigate.

we all know that once the dragon is found, the late captain montgomery's involvement will be revealed, and the team's involvement in burying that truth is going to be found out. with the new captain gates' ties to internal affairs, can we forsee a very bad train wreck in the future?

Good point, but if the end result is the team uncovering the involvment of a much higher ranking cop or city official, it might be grounds to lighten their punishment.  Something called mitigating circumstances might be considered.  But this is something interesting to keep in mind for the future. 

If a police captain is found dead, I'm sure a full-investigation would be launched, but it would find that Beckett and Castle weren't involved in any of the shooting since there would be no gun powder residue on their hands or clothes, Beckett's weapon wouldn't show evidence of being fired, and they could easily argue that they pulled up outside the hangar at around the time they heard shots fired, rushed into the hangar and found Montgomery and everyone else dead.  And with Ryan and Esposito corroborating that story, there wouldn't be enough to look into the case further.  Plus, the department wouldn't want any more embarrassment to come to it from exposing Montgomery's shady past.

i wonder if someone in internal affairs knows. maybe that's why gates is now captain at their precinct, as a cover to find out more. they could be looking for those police files montgomery mailed away before his death. gates who get major brownie points for digging up the truth in something this potentially high-profile… just what she needs to rise up in the ranks.

what could be more scary is that The Dragon could be involved in this as well… but again this is all speculation by caused by OCD on my part [Image Can Not Be Found]

It does make you wonder if The Dragon had Gates assigned there to keep an eye on everyone and, in particular, to get rid of Castle or at least keep him on a very short leash. 

Well, no one that we we know, knows that Roy even had original files, or that he mailed them. IA could cross-check Capt. Montgomery's cell phone records, as well as Beckett's, Ryan's & Esposito's phones. But I don't think they would have recordings of those calls, only the text from Esposito would require some creative storytelling. But they wouldn't necessarily be able to get to the conclusion that Rick or Kate talked with Roy in the hangar before the shootout. There were no witnesses left alive (except C & B) to that critical piece of information. C & B could truthfully testify that Roy had called them to meet him there, and that they entered the hangar after hearing the the shoots. Depending on how much pressure the interrogator could bring to the questioning (as the investigation would have barely started by the time of Roy's funeral & Kate's shooting), IA may run into a dead end. As I think about it, isn't IA only interested where there is evidence of illegal/unethical actions by police officers? There would be serious questions about why Capt. Montgomery was killed and why his star detective was shot, but that, by itself, does not point to official misconduct by either of them. Would there be an energetic investigation? Definitely. But IA? Umm… I'm not so sure.

hm… what about all the police reports in records that were altered? who is changing them? someone must be going through everything trying to eliminate evidence, and i am wondering if montgomery pulled the files he had in his possession before they would be altered as well… or made to disappear, like the paperwork johanna beckett had in her posssesion before her murder.

 

what if…those missing files are actually the ones montgomery had???

Apparently, those were altered by Montgomery – and only Castle, Ryan & Esposito know which ones they were. And they are not telling.

Hopefully we will find out about the files Roy had, what was in them and who got them.

I think this is an excellent topic.

This is why I want Victoria Gates to recieve the envelopes from monty. It makes perfect sense in the storyline for her to have the files and NOT alexis.

She could show up a facade of being cruel but we the audience know the truth. That would put a human touch to Gate's chracter. Right now she is painted as cold and cruel.

I know there is a theory that Alexis ends with the files and hides them. This is highly possibly, knowing her storyline in season 4. But I dont want it to happen.

Castle, we know does not end up with the files as it was confirmed by nathan in comic-con.

The only other options are alexis and the captain. And I want it to be the captain.
