Sam said to Carol, "Kim is going to sell me a good used car next Monday and then I’ll deliver it to you in exchange for your computer, but I’d like to have the computer now." Relying on this statement, Carol delivered the computer to Sam. Sam knew Kim had no car and would have none in the future, and he had no such arrangement with her. The appointed time of exchange passed, and Sam failed to deliver the car to Carol. Has a crime been committed? Discuss.
