Kat and the Mystery of the Disappearing Glasses

At 2pm, in broad daylight (though it was a bit overcast), Fiona T. took off her glasses at the San Diego Zoo and attempted to put on a tiger mask. Her mother took pictures of her brother, Alex, and sister, Kat, who had also donned masks of different animals. Fiona unfortunately did not get her mask on in time to be in the photograph and her mother, noticing Fiona's unhappiness, decided to create another photo opportunity for her with stuffed animals. Fiona happily made it into this one and all was right with the world... until she realized her glasses were missing.

Within the 7 minutes that this scenario played out, where could her glasses have gone? Fiona had no recollection. We checked pockets, bags, the mask stand, the cashiers, everything. Nothing.

Then a thought entered Kat's mind. What mattered most in a case: evidence. Where did we have evidence: the camera. Excited, she flipped through the camera to look at the pictures of herself and Alex. There was Fiona in the background, glasses still on looking at a mask. Then a picture with her glasses off somewhere off to the left, getting ready to get into the shot (but not quite making it). But in between those two images... a picture of Fiona off to the very side on the right. Why would she need to go to the right - the mask stand wasn't there, nor was that where she wanted to enter the image... it could only be to...

Kat ran over to the bracelet stand which was to the far left of the masks and there, hidden under the stand were Fiona's glasses.

Evidence win.

Detective'd.
