Where is the prospector's lockbox?

[[PSI] Garrus]

I have completed every side mission. I now have "An employee is late and now missing - search the prospector's lock box" which it tells me with a big ( ! ) that it is somewhere near or in the infirmary building, one of which the double doors are locked in the prison but I cannot for the life of me see the case anywhere. I have even gone back to dead bodies to see if it would trigger something or if I left anything behind.

I ask if this is bugged because the game tells me to complete any unfinished side quests before I return with the detonators, which would imply there is no turning back at that point.

It's in the infirmary building...under one of the beds.

Thank you Foxen, I somehow missed the box entirely every time I walked around in here lol

For those needing more clarification too, it's in the building with the beds, kitchen and locked numbered lockers, there are some flipped over beds and frames, there is 2 beds with mattresses and blankets in the room and the box is under one of the beds with a mattress and blanket still on them.

This video shows you the body that has the key and where they are, how to get there.

6:04 if you just want to see the map location in general but you do have to get all the way down to the bottom of the river somehow. Hope you find it!
