At the start of the game in the hospital, there is a box with a heart inside. You need a password to open it. The clue is "Remember, the three beauties who cause it to pump so are the key, 'age before beauty'". The code is "23, 31, 19" (via the order you will find them in).
Unlock the Night Vision Goggles, and have them equipped. In the Exam Room of Alchemilla Hospital is an X-ray screen with "Sarah 19" written on it. Examine the X-Ray while wearing the Night Vision Goggles. You will see an image of the Goggles on the screen. The image changes location, and seemingly its shape, if you alter your position in front of the X-ray before examining it.
