Nah, only two specific drawers that are locked (on purpose I guess), but I wasn't able of opening them at all.
I wasn't able of finding anything that could help me opening them too... :/
Ahh, got you. You find the item you need after you use the glasses. The glasses have an unorthodox use to open up something else first. There's a few subtle hints in the evidence pick ups.
ohhhh! I see! That unorthodox stuff is what gets me every time. Thanks for the tip though!
No problem, hope it helps.
