Murder-Suicide

Around 2 percent of suicides in the United States are accompanied by the murder of at least one other person. It averages out to slightly more than two murder-suicides per day. Nearly 90 percent of "ordinary" murders are committed by men, who also make up most (at least 75 percent) of the body count. With murder-suicides, the figures are significantly different: the perpetrators are male more than 90 percent of the time, while 75 percent of the victims are female. Both murder per se and suicide per se involved firearms between 55 percent and 70 percent of the time. The rate in murder-suicide is considerably higher, with some studies returning rates approaching 100 percent.
