Assume that this is what happened: Bruce and Jeff were camping in a remote location in central Nebraska. Bruce became suddenly ill, and Jeff decided he needed immediate help. Jeff jumped on Bruce's snowmobile and rode it to the nearest farmhouse to ask for emergency assistance. Jeff says that he did not know that Bruce kept a loaded rifle in a storage case on the side of his snowmobile. How would the prosecutor,plan his or her case presentation for the case above against Jeff? What elements would need to be proven and what facts would be used to prove each element? What defenses would be available to Jeff in this circumstance? What evidence might he offer to assert his defenses?
