Not to plug my own reporting, but I now have the police report on Buzzy.
Key takeaways:
-Disney didn't report the theft. Orange County Sheriff's Office heard rumors of it on Nov. 26, 2018, called Disney, and Disney confirmed it had been stolen at least a week earlier
-The scene was then searched. Description largely matches rumors that came out a month later of hydraulic lines being cut, fluid spilled, etc. No fingerprints found.
-In July, police caught wind of Hoot Gibson's (aka Dave Ensign) claims about Buzzy being in Disney's possession. They searched a WDW animatronics lab and determined he wasn't there, and employees said Gibson was not "anyone who would have the access required to know what is housed in the animatronics lab."
