I actually think it was planted. It was a large amount, she's a beautician, she's running over to Bali for a quick holiday, and it shows up easily found in her bag?
I ask because I get a ton of laptop bags as meeting goodies, and I'm always finding interior zipper pockets in the weirdest places long after I've used the bag for a few trips. I could see a surfing board bag having interior pockets for carrying cords, wax, repair kits, tools, additional fins, wet bathing suits, etc.
