My friend(bob) replied to a Craigslist ad for buying/selling vintage jewelry,things etc....Jennifer answered Bob with a day time etc she would come over and see. That day comes and she is shown vintage jewelry,inc.a Rolex watch and 3 necklaces of real pearls,27sets of vintage earrings &10 bracelets with semi-precious stones, 3 vintage paintings,4 small statues from Italy etc.. Jennifer tells bob that she sells things to vintage and antique shops ,especially for a shop well known in Burbank on Magnolia ave. Jennifer works for said owner of shop, and states that shop owner will buy all of this now. jennifer and Bob load her car with everything and they both go to see the shop owner. Shop owner was not in.so they go to an atm so that Jennifer can pay for the things that she, herself, wanted.She has wrong atm card so she takes Bob home with a promise to come back with the amount they agreed on. parked in front of bob's home,Bob gets out to unload the car . Bob sees a friend of his on the front porch, he walks up to the friend and an argument starts. Jennifer sees this and drives away with all the merchandise. Bob texts and calls jennifer. She makes appointment to come back then cancells for a different day. Bob is furius at this point and sends a flurry of texts which she responds that she left everything at the police dept.Bob goes to the police and is told there is no holding without a claim number which he does not have. He goes to Jennifers house and her Father answers the door (oddly enough wearing the Rolex watch). Her Father bruskly tells Bob to get off the property. Bob then sends a signature requiered letter (according to law) for his things to be returned. letter comes back unopened and unsigned some weeks later. These are second hand things, other than a inventory sheet and a few pictures, I know the value to be about $ 9,000. Can we prosecute?
