Sir: Siblicide—the killing of one sibling by another—is rare relative to other types of homicide. Underwood and Patch (1) reported that of 65,390 homicides coded in the Supplementary Homicide Reports (SHRs) of the Federal Bureau of Investigation (FBI) for the years 1993 through 1995, only 572 (0.9%) were cases in which the offender and victim were siblings. Even if including only intrafamilial homicides, siblicide is infrequent, with just 996 of 13,105 (7.6%) coded as sibling homicides in the… 
The Evolutionary Psychology of Sibling Conflict and Siblicide
Conflict between siblings is common, not only in humans, but also in a wide variety of other species. It is also an unsurprising phenomenon, as offspring compete for dominance as well as food
Siblicide and Genetic Relatedness in Chicago, 1870-1930
Using a sample of siblicides committed in Chicago from 1870 through 1930, the authors tested two predictions heuristically guided by an evolutionary perspective. They predicted a greater proportion

The article's aim is to evaluate the application of the evolutionary principles of kin selection, reproductive value, and resource holding power to the understanding of family violence and concludes that most of the evidence is consistent with evolutionary predictions derived from kin selection and reproductive value.

Siblicide has been overlooked in both the family violence literature and homicide studies. This is unsurprising as sibling abuse research in general has remained on the periphery until recently, and

Summary. Trivers (1974) argued that offspring demand much more parental investment than parents want to give. This confl ict of interest stems from a genetic confl ict. Parents are genetically
Juvenile Involvement in Fratricide and Sororicide: An Empirical Analysis of 32 Years of U.S. Arrest Data
Despite the interest in juvenile homicide offenders, few studies have systematically examined their involvement in incidents involving specific victims. This study focused on one victim type, the


Siblicide and Seniority
An analysis of the Canadian data suggests that the rate of siblicide is unaffected by the age difference between siblings, and the substance of lethal sibling conflicts is discussed in the light of these results, case descriptions, and literature on nonlethal sibling conflict.
Siblicide A Descriptive Analysis of Sibling Homicide
This study presents a first look at the phenomenon of siblicide on a national level using data from the Federal Bureau of Investigation's Uniform Crime Reports and the Supplementary Homicide Reports to indicate a stable trend in the frequency.
A Contextual Exploration of Siblicide
This article contextualizes the exploration of sibling homicide with the use of the Supplementary Homicide Reports and suggests that siblicide may be examined within the theoretical contexts of sociobiology and routine activities theory.
An exploratory analysis of the contexts and circumstances of filicide‐suicide in Chicago, 1965–1994
Filicide is the killing of a ward by a parent. Relative to many other types of homicide, filicide is an infrequent event. Filicide followed by the offender's suicide is less frequent still. The
Methods of filicide: stepparents and genetic parents kill differently.
Using a United States national-level database of over 400,000 homicides, results replicate those of Daly and Wilson (1994) for genetic fathers and stepfathers and identified similar differences in the methods by which stepmothers and genetic mothers committed filicide.
