triple homicide

Triple homicide is an American legal and journalistic designation for a case in which three people have been killed within the same sequence of events or the same investigation. The term belongs to US law and practice and has no direct counterpart in Danish legislation. It is not an independent, codified offence in the U.S. Code: there is no federal provision that specifically criminalises 'triple homicide' as a separate category. Instead, such cases are treated legally as three separate killings falling under the relevant state or federal law, depending on the circumstances and the jurisdiction.

At the federal level, murder is defined in 18 U.S.C. § 1111 as 'the unlawful killing of a human being with malice aforethought' and is divided into first and second degree. In a case with three victims, the indictment may therefore consist of three separate counts of murder under this provision — or under the corresponding law of the state in question if the case is handled at state level, which is the most common situation.

In practice, 'triple homicide' is used primarily as a descriptive term by police, prosecutors and the media to signal the scope and gravity of a case. The designation captures the fact that three human lives were lost in one and the same case, and it carries considerable rhetorical and procedural weight — for example at sentencing, where the number of victims may support harsher penalties or, in certain states, the death penalty.

In the cases on Krimidex where the term appears — including the Grant Amato killings in Florida in 2019 and the Starved Rock murders in Illinois — 'triple homicide' is used in exactly this descriptive sense: as a collective label for a case involving three homicide victims, without altering the underlying legal classification of each individual killing.
