Anchorage War Memorial Walkthrough - Fallout 3 - Page No. 4
After you have collected everything of interest, drop down through this opening in the floor.
You'll want to hack the computer to get info on the stash and unlock the safe in the clinic. You'll also want to search Ted's body, which is in front of the doors.
Collect everything in the clinic, and don't forget the safe in the floor under the desk.
Once you have collected everything of value in the area, you'll want to head back down to the Utility Door in the Anchorage Memorial Service Entrance.
There is a lot of stuff in here, so make sure you don't miss anything.
The key to the stash is also on the shelf. You will need it to unlock the secret compartment in the back of the fridge.
