Methods of filicide: Stepparents and genetic parents kill differently

Stepparents commit filicide at higher rates than do genetic parents. According to M. Daly and M. I. Wilson (1994), motivational differences generate differences in the methods by which stepparents and genetic parents kill a child. Using Canadian and British databases, Daly and Wilson (1994) found that stepfathers were more likely than genetic fathers to commit filicide by methods revealing feelings of bitterness and resentment not present to the same degree in genetic fathers. Genetic fathers, in contrast, were more likely than stepfathers to commit filicide by methods that often produce a quick and less painful death. Results replicate and extend previous research conducted by Daly and Wilson (1994). Discussion addresses stepparental psychology, limitations of the current study, and future directions for research and clinical application of this topic.
