I can't imagine he could get through there, if he is 6' tall. Your shoulders would limit you from squeezing through. I would be afraid to even attempt that. Have they really searched all the vents as well as they can? He has got to be stuck in there in some spot. How would he navigate a 90 degree angle or sharper? Reed Richards could easily do it.
i dunno, if i was going to get gang rape in a prison, i'm pretty sure squeeze through whatever hole got me the hell outta there. screw jared, this guy should be the subway dude.
