NARRATOR: Last time, on 'ISU VRAC: Ballistics'

[descending establishing shot on Biorenewables Complex]
[camera shutter fires multiple times, taking photographs of students on the ground, lifeless]
[cut to inside the building, next to the staircase, camera parallel to the ground, yellow police tape in the foreground, PAUL slowly stepping in-between the bodies as he takes pictures, various personnel scattered around the scene]
[STEPHEN and ELIOT stride into shot from behind the camera, ducking under the police tape and approaching PAUL]
STEPHEN: Paul.
[Paul glances up]
PAUL: Detectives.
[ELIOT glances around]
ELIOT: What have we got
[PAUL continues to take pictures as he speaks]
PAUL: Welp... 12 victims... Ages all around 20... 
STEPHEN: Any other links?
PAUL: No... We ran I.D. ... All from different ends of the country... All from different schools
ELIOT: Then what were they all doing here together?
PAUL: We got flight receipts... They all flew in on the same day... But after that records lose track of them
STEPHEN: What's the indicator for cause of death?
[PAUL stops and turns to face STEPHEN and ELIOT, face grim]
PAUL: That's just it. We've got no signs
[ELIOT frowns]
ELIOT: But whoever did this must've dragged their bodies in here. No way you move 12 fully grown adults without a trace
[PAUL shakes his head]
PAUL: We've checked 3 times already. Nothing. No external trauma, no bio residue, no prints. Everything indicates that they were in full control up until they were gone.
[zooming close up of STEPHEN as he slowly takes off his sunglasses]
[ELIOT looks at STEPHEN]
ELIOT: Was this some kind of group suicide?
STEPHEN: No... Look at their faces. They're tired and despairing. Something got them, and they must've gotten a glimpse of it.
[STEPHEN looks at ELIOT]
STEPHEN: The killer was in the building with them
PAUL: There's something else you should see
[PAUL proceeds up the stairs]
[ELIOT and STEPHEN glance at each other then follow PAUL to the top of the stairs]
PAUL: Take a look
[ELIOT and STEPHEN look down]
[zooming close up of ELIOT as he slowly takes off his sunglasses]
ELIOT: They're... They're spelling a word
[STEPHEN grimly whispers]
STEPHEN: R E U...
[cut to STEPHEN's perspective, looking down on REU!]
[unnamed personnel approaches]
PERSONNEL: Someone just posted a picture on this SPIRE-EIT site
[picture is the same as STEPHEN's view]
[ELIOT turns back to look down again]
ELIOT: We just found our vantage point. Track that i.p. and get me the autopsy report
[fade to black then into opening]

ADAM: So, while loops
[ropes descend onto chairs, floor falls out]
TIGER: Aw shoot, here we go again
