340 gone! Performance shop shut down! Help!

Also in a lot of states $3,000 in fraud is a felony.

The DA just didn't want to mess with it and file charges against the owner.

Make them. (I would be on thier *** about it and insist they file charges) with the stipulation that the charges will be dropped if they evened up with me.
You have been defrauded and had your property stolen and you want to file charges.
Use that exact wording.

They HAVE to do it.

Not only $3000 in cash but the value of the engine too! Don't forget that this engine is worth even more considering it was out of a matching number car!

God this thing has got me so riled up I could barely sleep last night. This f*cking guy has it coming to him. Karma is a *****!
