As early as November 11, 1976, D threatened LaPorte with serious bodily harm because LaPorte was spending time with D's wife. Also, as of that same date, D and his wife were contemplating legal separation. Several days later, D agreed to a divorce on the condition that his wife would not see LaPorte or any other man for two months. Shortly thereafter, D agreed to permit his wife to see LaPorte in public. Upon seeing them together in public, D became upset and decided to leave Massillon for a while. On the night of December 16, 1976, with D's return to Massillon, D admitted telephoning his wife at her home. LaPorte was there and D threatened him with serious bodily harm. D's wife telephoned the police. The police report includes (1) D's wife's statement that D was holding a gun to the telephone and clicking it during his conversation with her; and (2) LaPorte's statement that D had threatened to kill him. While the police were still on the scene, D telephoned a second time. Defendant admitted that he conversed with the police during this second call and that he informed them that he owned a .22 caliber weapon. Four witnesses testified that D had threatened LaPorte sometime during the months of November and December 1976. In a handwritten last will and testament dated December 18, 1976, D left his property to his sisters and his life insurance to his stepdaughter. The next day D purchased a Winchester 30-30 rifle from a local store. On December 22, 1976, D spoke to his wife, LaPorte, and some of his wife's relatives and friends on the telephone. During these calls, a fight between D and LaPorte, which never materialized, was discussed. At approximately 6:00 a.m. on December 23, D went hunting for LaPorte at his place of work. D learned from LaPorte's brother that LaPorte was still at home where he was preparing to depart for the restaurant. D drove to LaPorte's home. D arrived around 6:30 a.m. as LaPorte had just entered his vehicle. D repeatedly fired a long-barreled automatic weapon containing 30-30 ammunition at LaPorte, killing him. The killing was witnessed by LaPorte's mother. D fled the scene and admitted the killing to a Massillon newspaper editor. In 1977, D moved to Florida, and, in 1978, emigrated to Australia. Following ex-tradition proceedings, defendant was returned to the United States in 1979. D pleaded not guilty to aggravated murder. The jury was instructed on aggravated murder; on the lesser-included offenses of murder, R. C. 2903.02; on voluntary manslaughter, R. C. 2903.03; and on the defense of insanity. D was found guilty of aggravated murder and appealed. It was affirmed. D appealed. D claims the court's instruction on voluntary manslaughter was prejudicial because it included inadequate definitions of both extreme emotional distress and serious provocation. The appeals court held that D was not entitled to an instruction on voluntary manslaughter.
