Great news! Sounds like the thieves dropped them off at the gate where they would be found. I'd bet the thieves felt pressured by the mainstream reports.
From the Museum FB post:
STOLEN BONSAI RETURNED! We are pleased to report that the two bonsai stolen from our secure, public exhibition space on Sunday, February 9, have both been mysteriously, miraculously RETURNED to the Museum.
Security guards discovered the pair of bonsai sitting on the road leading to the Museum at approximately 11 pm, Tuesday, February 11.
Museum Curator Aarin Packard says they are, fortunately, in fairly good shape. “The Silverberry suffered some damage. It has some broken branches, probably due to improper transportation and handling, but both bonsai trees and their pots appear to be intact, which means they can return to being on public display.”
The bonsai will be back on public display by 12:00 noon today -- COME VISIT them! Additionally, the Japanese Black Pine, originally grown from seed by Japanese American Juzaburo Furuzawa while he was incarcerated during WWII, will resume its position as the centerpiece of Pacific Bonsai Museum’s upcoming special exhibition, World War Bonsai: Remembrance & Resilience, opening May 8, 2020.
THANK YOU to everyone who helped share the news of the missing bonsai and perhaps made them 'too hot to hold.' We are so grateful to all of you.
We have also noted your good suggestions that we could use a security system upgrade, and already some community members have pledged their support to help us implement an upgrade. Please join them by taking a stand for bonsai:
