There is an overlap between mass shooters and incels as well, with several inspired by the same shooter, Elliot Rodger.
And as for domestic violence:
The massacre at the University of Texas at Austin occurred in 1966, when student and ex-Marine Charles Whitman took his guns to the university’s clocktower and fired at people on the campus below, killing 14 and wounding 32 people (one person would die later of complications related to a gunshot wound). A week after the shooting took place, a Travis County Grand Jury declared that Whitman was an individual who had “suddenly gone completely berserk, with no warning to his family or friends.” But the Travis County Grand Jury was missing crucial information. Although acknowledging that Whitman had first killed his mother and then murdered his 23-year-old wife in the hours leading up to the shooting, the jury—like most Americans even today—did not recognize that domestic murders represent the far end of a continuum of ongoing abuse rather than a sudden or random incident.
What we can learn from the tragic archive of Kathy Leissner, wife of UT-Austin mass shooter Charles Whitman.
54% of mass shootings between 2009 and 2016 were directly related to domestic or family violence — meaning that a current partner or family member is one of the victims. In one of those cases, Cedric Anderson walked into his new wife’s elementary school classroom in San Bernandino, Calif. in April and killed her, an 8-year old special needs student, and himself. But even among the other 46% of mass shootings that don’t directly involve an intimate partner, many of the attackers have a violent misogynistic incident in their past. The Everytown study found that 42% of all mass shooters had exhibited at least one warning sign, such as a prior violent act or domestic violence incident.
