Facts

The defendant, separated from but still married to his wife and attempting reconciliation, returned to the marital home and observed an unfamiliar man with his wife. After further observation, he burst into a downstairs bedroom and found his wife and the victim nude and engaged in sexual intercourse in the defendant's home. He fired a single shot into the victim's hip; the victim died sixteen days later from a massive infection resulting from the wound. The defendant had never previously met the victim, and the proof showed severe emotional stress surrounding the marital separation and the discovery.

Issue

Whether, on these undisputed facts, the defendant's killing of his wife's paramour could support a conviction for first-degree murder, or whether the provocation was legally sufficient to reduce the offense to voluntary manslaughter.

Rule

When a defendant kills after encountering a spouse engaged in unlawful sexual intercourse, that discovery is, as a matter of law, sufficient provocation to reduce the homicide from murder to voluntary manslaughter, so long as the killing occurs before the passion has cooled and there is no evidence of actual malice such as a prior grudge, revenge, or similar motive. It is not necessary that the defendant be incapable of deliberation; it is enough that the circumstances would produce such excitement and passion as would obscure the reason of an ordinary person and induce the fatal act.

In Nashville, Owen Mercer and his wife had been living apart for one month but remained married and were attending counseling in hopes of reconciling. Owen returned to the marital townhouse unexpectedly and, upon opening the bedroom door, found his wife and an unfamiliar man nude and engaged in sexual intercourse; Owen instantly grabbed a heavy lamp and fatally struck the man.

Under the majority rule, what is the highest homicide offense the evidence would support absent proof of a prior grudge or revenge motive?

Explanation. The majority treated the actual discovery of one's spouse engaged in unlawful sexual intercourse as sufficient provocation as a matter of law to reduce murder to voluntary manslaughter, so long as the killing occurs before passion has cooled and there is no evidence of actual malice such as a prior grudge or revenge. It is not justified homicide, but neither are malice and premeditation established on these facts.
