Empirical analysis of homicides in which children have killed parents has been limited. The most comprehensive statistical analysis involving parents as victims was undertaken by Heide and used Supplementary Homicide Report (SHR) data for the 10-year period 1977 to 1986. This article provides an updated examination of characteristics of victims, offenders, and offenses in parricide incidents using SHR data for the 24-year period 1976 to 1999. The analysis proceeds in two stages. First, offense (homicide circumstances), victim (age, race), and offender (age, race, sex) correlates are reported. Second, juvenile involvement in incidents in which parents were killed is examined and a determination is made whether changes in youth involvement in parricide offenses are discernible over the 24-year period. The article concludes with a comparison of findings that emerged from 24 years of data with those from the earlier 10-year period and the discussion of the significance of these findings.
