A friend of mine has been experiencing weird things.

These two photos got dropped off in the middle of the night at his work , security cams show a man walk up , slide the photos in between the doors , he picks something up and walks away . I have a video of that as well . On the back of the photo taken from a plane , written in Finnish “I cried when the plane took off” I tried reverse image search and found a possible navy base for that photo but nothing for the girls . Any possible ideas what could be happening ? Also probably unrelated but it seems like things move in the middle of the night there inside , caught on camera multiple times with no explanation .
