I am scratching my head wondering how a dirt pusher "stole" your trees and money. I presume you hired them, paid $8500 for a pond, but it failed to hold water? If this is the case, you may have a civil claim (probably a weak one), but the "criminal intent" element seems elusive...again, if hired, the only possible criminal intent I could think of would be intentional fraud...Did the trees get sold by the dirt pusher?
