Logs 1 and 3. I think I can find them on my own.

Log 1 is in the same area where you get introduced to the scanner. Look by the door leading to the fight with your first zombie.
Log 3 is in the room that's full of zombies. Note that you can roll Miri's head back out to the first hallway (though you can't follow her body); you can, however, reach the back wall of the room without getting torn apart.
