Alright here's what I did. My murder plan was to attack someone with the rifle as a blunt weapon. I left a bunch of things all over the place to figure out my alibi.
0:00 - I watched everybody else leave the dorms. According to Multi:
Wiing left dorm area via stairs. Phinerxen left via mess hall. Vucub left via the other hallway. Desta didnt leave.
0:05 - I went to the lounge to grab the rifle. Desta passed me and went into the library, then Vucub exited the library and went back through the dorm hallway.
0:10 - I went to the workshop, and balanced the nail next to the door.
0:15 - I went through the animal bio lab to get to the chem lab, and took a bunsen burner.
0:20 - I went to the kitchen and put a snack in the deep fry machine. (Either Multi mod derped here or somebody had code to stick their hand in boiling oil and get stuff out.)
0:25 - I arranged the gas container/bunsen burner in the kitchen door. I took a knife and left through the unblocked door.
0:30 - Arrive at chem lab again. I set up the bunsen burner and beaker. (I'm pretty sure it was supposed to be on.)
0:30 - 0:40 - I emptied all the chemicals (except the knockout and flammable chemicals, which were gone) into the large beaker. I then searched for dirt or dust to add to the chemical mix and could not find any. I blocked the front door with the stool and the back door with the chemical vials as I left.
0:40 - 0:45 - I passed through the plant bio lab on my way to the animal bio lab and was brutally assaulted by Vucub throwing a tomato at me. (Vucub was also blocking all the sinks)
0:45 - 1:00 - I found that the animal lab was chaotic, with all the animals except the tiger and piranhas freed. My plan was to try to feed the parrots to the piranhas until somebody I could beat to death walked through the door, but nobody did and apparently I was unable to catch the parrots.
Night ended at 1:00.
