"firearms are the most common method of fatal suicide by women as well as by men in the United (Gold, 2006)."
"Mothers who committed FS were more likely to have an altruistic motive for the filicide, use the same method for both acts (particularly firearms), kill older children, and be married, than the other mothers. Married women are ordinarily at lower relative risk of suicide than unmarried women(..)"

"Depression was frequently present. Mothers who committed FS were less likely to be delusional than the other mothers. This may be because nondelusional mothers were more able to plan and execute the dual acts of filicide and suicide."

"The majority of mothers in each group had previous mental health treatment (70%–79%). Contrary to our hypothesis, women who committed FS had a trend toward being less likely to have had a known previous psychiatric hospitalization."

"In summary, our study findings confirmed the hypothesis that mothers who committed filicide–suicide or filicide with nonfatal suicide attempts predominantly had altruistic motives."
"Mothers who committed filicide–suicide killed older children."

"A Canadian study noted that mothers who killed their older children were more likely to also commit suicide than those who killed their infants (16% vs. 2%; Daly & Wilson, 1988).

"In an Australian sample, it was noted that sometimes ‘‘the mother’s efforts to
care for the children are reflected in the planning and preparations to ensure that she is successful in her efforts’’ at filicide–suicide (Alder & Polk, 2001, p. 51)."

"At the time of the offense, most of the perpetrators were suffering from a psychiatric illness, usually depressive disorder.
Nearly one-third were in a psychotic state."

"Consistent with results of some studies,6,30,48 a higher proportion of children killed by their fathers were male, but the difference between genders in this sample was not statistically significant. Rodenburg6 demonstrated that perpetrator gender correlated with victim gender, with fathers more likely to kill boys and mothers tending to kill girls.6
Violent methods of killing (i.e., shooting, beating, stabbing, and strangulation) were used in 85 percent of cases, characteristic of other reports of a high frequency of violent means employed by male
perpetrators of filicide."

"Our findings also differ from reports of related substance abuse in cases of paternal filicide as use of drugs and/or alcohol at the time of the offense was indicated in only two cases."

"5 Of the 19 offenders in our sample who were determined to have had agency contact prior to the filicide, 12 (63%) had a history of violence toward their children and 7 (37%) had not been violent toward their children."

"Early recognition of psychiatric illness is essential. The possibility of homicidal tendencies in depressed
fathers, particularly when suicidal ideation is indicated, should be assessed systematically as part of any psychiatric evaluation. Direct questions as to the status of the marital relationship and family violence and child abuse may help to identify fathers at risk for filicide."

"Filicidal mothers showed mental distress and often had psychosocial stressors of marital discord and lack of support.
They often killed for altruistic reasons and in association with suicide. Maternal perpetrators also dominated in filicide cases in which death was caused by a single episode or recurrent episodes of battering. Psychosis and psychotic depression were diagnosed in 51 percent of the maternal perpetrators"

"Altruistic filicide is committed with the motive of relieving the child of real or, most often, imaginary suffering, and usually involves a suicide attempt by the parent."

"Almost all maternal perpetrators reported high levels of stress and lack of support and resources at the time of the filicide. In general, maternal filicides could be divided into two major categories: altruistic motives and maltreatment.
Most maternal perpetrators had altruistic motives and had depression or psychotic illness, supporting findings in studies of maternal filicides.10,20,31

Perpetrators of the altruistic type were older, had a higher level of education, and were mostly employed. They were also in contact with the health care system and were even undergoing treatment.
Maternal perpetrators of the second category were abusive and had features that are frequently reported in abusive parents: being the primary caregiver, caring for a child that is not biologically related to the present partner, having a low income and education level, being in an ongoing abusive relationship, having conflict with family members, and having limited social support.1,5"

"Paternal perpetrators, on the other hand, were jealous of their mates, had a personality disorder (67%), abused alcohol (45%), or were violent toward their mates."

"Fathers were violent to family members, abused alcohol, and had personality disorders, as verified in other studies.23,32 The presence of reported significant life stressors included impending marital breakup, jealousy, fear of separation, long-term substance abuse, and low education level and socioeconomic status."

" Hatters Friedman and colleagues20 found that maternal motives for filicide were predominantly altruistic (misguided love) or acutely psychotic (without rational motive)"

Grupp other filicide:
" Eighty-four percent of the mothers and 70 percent of the fathers were married or cohabiting, and the rest were single parents or divorced. Seventy-one percent of the mothers and 75 percent of the fathers were semiskilled or unskilled workers and of low socioeconomic status."
-------------------
"34 percent of the maternal and 50 percent of the paternal filicides, the death was said to be accidental. Six fathers in a state of jealousy intended primarily to kill their wives, and three succeeded in doing so. Only one filicide was reported to have been committed in revenge, however. Thirty percent of the fathers and five percent of the mothers were under the influence of alcohol at the time of the filicide.

Mothers killed their children by drowning (33%), strangulation (31%), or banging the child against a hard object (21%).
The most common methods of killing by fathers were banging the child against a hard object (36%) and strangulation (28%); a firearm was used by 17 percent of paternal perpetrators."

"The intelligence tests revealed that the perpetrators were of average intelligence. Only three mothers and one father had an IQ less than 80."

"Neonaticides were included only in the first sample, as were filicide-suicides. In those cases, information on the family's circumstances, the victims, and the perpetrators was not available, as often all the family members were killed. The lack of information concerning those cases reduces the comparability of the sample with others."
