I found a crate in the warehouse by the crying baby by climbing up on the boxes on the second floor, then opening the floor hatch to go back down to the first floor. Damned if I can't find the key to open it though.
I kind of gave up on it for the time being, and in the caves now, however it's bugging the crap out of me.
Also I had no idea you could get into the crying baby room. I tried all kinds of stuff to find out what was going on there to no avail.
Maybe a small nudge will tempt me to head back that way.
