West office still appears red on map. What am I missing?

I'm pretty sure I picked up everything. The safe is open and empty. Leon's desk is unlocked and empty. The 2 doors are open. I have been around the room several times and I see nothing.

Have you checked the locker? There is one near the office with the safe.

Thank you. This is what I missed.
