"Filicide" is the deliberate act of a parent killing his or her own son or daughter. The term can also be applied to the parent who has committed such an act. The word ''filicide'' derives from the Latin word ''filius'' meaning "son".
In some cultures, killing a daughter who has disgraced the family is a common occurrence (see honor killing).
A 1999 http://www.ojp.usdoj.gov/bjs/pub/ascii/wo.txt US Department of Justice Study concluded that between 1976 and 1997 in the U.S., mothers were responsible for a higher share of children killed during infancy while fathers were more likely to have been responsible for the murders of children age 8 or older. Furthermore, 52% of the children killed by their mothers were male ("maternal filicide"), while 57% of the children killed by their fathers were male ("paternal filicide").
Sometimes there is a combination of murder and suicide in filicide cases.
