Murder–suicide
Theories
Though there is no national tracking system for murder–suicides in the United States, medical studies into the phenomenon estimate between 1,000 and 1,500 deaths per year in the US, with the majority occurring between spouses or intimate partners and the vast majority of the perpetrators being male. Depression, marital or/and financial problems, and other problems are generally motivators.
Theories
Homicides which are later followed by suicide often make headline news; national statistics indicate 5% of all homicidal deaths are caused by murder–suicides. The U.S. Department of Health and Human Services, Centers for Disease Control reports that an estimated 1 million adults reported attempting suicide in 2011, and there were over 38,000 completed suicides in the same period. The estimate of 624 murder–suicide events per year indicates that around 1.6% of suicides involve murder.
Murder–suicide
A murder–suicide is an act where an individual intentionally kills one or more people, before or while also killing themselves. The suicide may be in response to the guilt one feels for the murder, or to avoid potential punishments, such as imprisonment. Some forms of murder also inherently entail suicide; such as suicide attacks, or when the operator of an aircraft with passengers deliberately crashes it.
