Adopted children who kill their adoptive parents

The killing of parents, frequently referred to as parricide, is a disturbing phenomenon that often generates widespread media coverage. Most of the scholarly literature on this topic has focused on biological offspring who kill mothers and fathers. Some analyses have examined juveniles and adults who kill their stepparents. To date, virtually no research exists on children who kill their adoptive parents because this type of victim-offender relationship has been absent from available homicide databases, thereby preventing such analyses. The present study is a content analysis of news reports of 46 cases of adopted children who killed their adoptive parents in several different countries. Data pertaining to offender and victim demographics, incident characteristics, and the processing of offenders from the initial charge through conviction and sentencing are examined. To the extent possible, media accounts are used to classify cases according to motives or circumstances leading to the killings. The article concludes with a comparison of profiles of children who kill adoptive parents in relation to those who kill biological parents, important observations that emerged from these news accounts, and discussion of possible explanations of parricide by adopted children, including adopted children syndrome, reactive attachment disorder, and biological risk factors. Limitations of this study and directions for future research are addressed.
