Okay, so first of all, I have a theory, that Marvin IS Alter 5914, the sign says, "Alter 5914 is a Time Thief. Don't believe Alter 5914."

Marvin is trying to learn how to time travel in Argentum Inanis, so maybe he found the ability to time travel and somehow he was one of the prisoners or experiments in the IRIS facility. It did say Iris=Antimatter in his spellbook, so he must know something about them, maybe he was there at one point and he somehow escaped.

Maybe he used his powers to put Chase into the future a little bit more so that he could find out more about the facility. What if after the scientists have the chat with Chase, they relate the case back to Marvin, maybe he did something similar in the past...

Second theory, when Chase is looking at the what I'm assuming are the cameras at 21:18, there is a red light...

I think that that's going to give him flashbacks to Dark Silence, and maybe Chase is going to breakdown because of the event, because you can hear someone yell, "HAVE YOU EVER EXPERIENCED THE TERRIBLE OCCURRENCE THAT HAS IMPACTED YOU SIGNIFICANTLY?!"

Maybe he's talking to Chase about the occurrence that happened in Dark Silence, and he's accusing Chase of killing his family? And I think Chase says, "I didn't kill them." So that's going be the main plot for the video, them trying to figure out how Chase teleported, and we'll get to learn more about his past.

Third theory, there's something related towards monsters or otherworldly beings in this facility, or as they call them, "Alters", as we see in the signs:

So maybe there's something dangerous in this facility that they know about but they're keeping it to experiment on it, maybe THIS could be have possessed Chase, maybe when he says, "I didn't kill them." he was refdering to the security guards, and the scientists, because we see bloody corpses on the floor and someones bloody footprints.

In another shot we see scientists being dragged and thrown out of the door by some kind of telekinetic force, or invisible force, there is definitely something or someONE who is dangerous in this facility. Chase does say, "I'm not lying! You guys KNEW, and did NOTHING." So maybe he's talking about then keeping whatever dangerous entity in the facility that possessed him and made him kill those people, they covered up the deaths, and put him in quarantine. He didn't do it, something possessed him to it, maybe this could be Anti, because he seems to be following Chase around wherever he goes...
