To defend Mr. Corliss against his murder charge by using Illinois’ Use of force in defense of person statute, we must prove that Mr. Corliss “reasonably believe[d] that such force (that which was intended or likely to cause death or great bodily harm) was necessary to prevent great bodily harm to himself.” Prosecution may assert that because neither Barney Quill nor Parnell Quill were witnessed to be in possession of a gun during the incident that the shooting of Barney Quill occurred, Mr. Corliss had no reason to believe that shooting Barney Quill was necessary to prevent great bodily harm to himself. However, there are many facts to the contrary that can be used to infer that Mr. Corliss believed he was in danger of great bodily harm to himself.
