The accommodations are a little bare-bones.
"Although the remains are skeletonized, it is not clear how many years they have been there," a University of California, Berkeley spokesperson said in a statement.

I'd wager pretty long. I'd google it but then I'm on some list. >

It depends very much on the conditions where the body was found. Humidity, insect/rodent activity, and a number of other factors can greatly alter the time needed for remains to skeletonize. It can range from a number of months to a few years (more if anything was done to preserve the body like embalming). >

The thing that really boggles my mind about this is the line: unused residence hall at University of California.
Cal Berkeley's student housing crisis is acute, so much so that they had to retroactively rescind acceptances of students last year. And you're telling me that there's a whole residence hall just sitting empty? WTF? >

It wasn't empty though, there was a skeleton living there.
