This is really unfortunate. Sorry to hear!
Honestly this kinda sounds like an inside job to me. How would people have known what was in the truck without having a copy of the manifest?

PLEASE TAKE FURTHER NOTICE that under state and Federal law:- It is a criminal and civil offense to “buy or receive” property that has been stolen. Cal. Penal Code section 496(a).
If you quote laws, please check that what you're saying is correct :). You're misquoting the law here. It's only illegal if the purchaser is aware that it's stolen:
Every person who buys or receives any property that has been stolen or that has been obtained in any manner constituting theft or extortion, knowing the property to be so stolen or obtained
If the purchaser is a bonafide purchaser for value, and is not aware that the item is stolen, it's not actually illegal (eg see Uniform Commercial Code § 2-403). Of course, it varies by jurisdiction, but you're quoting Californian laws so I'm going with the relevant laws in California.
