The answer should demonstrate your ability to analyze the facts in the question, to tell the difference between material facts and immaterial facts, and to discern the points of law and facts upon which the case turns. Your answer should show that you know and understand the pertinent principles and theories of law, their qualifications and limitations, and their relationships to each other. Your answer should evidence your ability to apply the law to the given facts and to reason in a logical, lawyer-like manner from the premises you adopt to a sound conclusion. Do not merely show that you remember legal principles; instead try to demonstrate your proficiency in using and applying them. If your answer contains only a statement of your conclusions, you will receive little credit. State fully the reasons that support your conclusions, and discuss all points thoroughly. Your answer should be complete, but you should not volunteer information or discuss legal doctrines that are not pertinent to the solution of the problem. Unless a question expressly asks you to use California law, you should answer according to legal theories and principles of general application.

Facts: Vicky operates a successful retail computer sales business out of the garage of her house. Vicky told Dan that she intended to go on vacation some days later. Dan subsequently informed Eric of Vicky's intended vacation and of his plan to take all of her computers while she was away. Eric told Dan that he wanted nothing to do with taking the computers, but that Dan could borrow his pickup truck if Dan needed it to carry the computers away. While Vicky was scheduled to be away on vacation, Dan borrowed Eric's pickup truck. Late that night, Dan drove the truck over to Vicky's house. When he arrived, he went into the garage by pushing a partially open side door all the way open. Vicky, who had returned home early from her vacation, was awakened by noise in her garage, opened the door connecting the garage to the house, and stepped into the garage. When she saw Dan loading computers into the back of the truck, she stepped between Dan and the truck and yelled, "Stop, thief!" Dan pushed Vicky out of the way, ran to the truck, and drove off. He immediately went to Fred's house where he told Fred what had happened. In exchange for two of the computers, Fred allowed Dan to hide the truck behind Fred's house.

What crimes, if any have Dan, Eric, and/or Fred committed?
