Actually there would be a murder JUST OUTSIDE Disneyland. No one is declared dead on Disney property. Even if they're dead, they'll remove the body and THEN declare them dead so it isn't documented as someone dying on Disney property. People are fucked up.
For some reason I love how there's a Mickey balloon tied to his wrist like a little kid. I can imagine Sherlock letting go of half a dozen balloons before John army-level knotted that thing to him.
Also, we all know Goofy is responsible for this. He was running a human trafficking ring out of the underground tunnels, and Cinderella discovered the truth and had to be eliminated before she reached the authorities.
