NVDRS: National Violent Death Reporting System

^aParents can also be a stepparents or foster parents.

^bSubcategories are mutually exclusive.

^cIn 30 cases with parental intimate-partner violence, one parent of the child victim(s) was also a homicide victim (ie, familicide-suicide). In 5 incidents, a parent was severely injured by the other parent (the perpetrator) during the homicide-suicide incident but survived.

^dIn these cases, the children were mostly killed as a result of parental/spousal retaliation or to deprive the other parent of custody or visitation.

^**Items with less than 3 counts were suppressed to prevent potential identification of decedents.
