The Virginia shooter had a history of domestic violence. That's tragically ordinary.

Specifically, violence against women.

Alleged shooter James T. Hodgkinson reportedly dragged his daughter out of a neighbor's house by her hair in 2006, according to The Washington Post. When she attempted to flee in a car, Hodgkinson broke in and attempted to cut her out of her seatbelt with a pocket knife.

This isn't extraordinary. In fact, it's tragically ordinary.

A 2015 New York Times report found that in 57% of mass shootings, current or former intimate partners or family members of the shooter were among the victims.

In incidents that don't involve partners or family — like in the recent attack on the Republican congressmen — the killer still frequently has a history of assault against a female partner or family member.

The kind of mass violence that devastates whole communities and rips apart the lives of strangers often begins at home. For the perpetrators of 12 of the most high-profile mass attacks between 2012 and 2017 around the globe, women were their first victims.

1. Esteban Santiago, who killed five at the Fort Lauderdale airport, was arrested the previous year for hitting and strangling his girlfriend.

"Santiago verbally assaulted his then girlfriend, a 40-year old mother of one child from a previous marriage whom The Daily Beast is not naming, through a locked bathroom door, telling her to 'Get the fuck out, bitch.' After he forced his way in by breaking down the door, he smacked her in the head and strangled her." — The Daily Beast, Jan. 7, 2017

2. Omar Mateen, the Pulse nightclub shooter, allegedly attacked his wife numerous times, which prompted her to flee and file for divorce.

In Sitora Yusufiy's own words: "Once, he woke up to find me on the phone with my cousin and started kicking me. He threatened to kill me if I left him. Another time, I was asleep in front of the TV when he pulled me up by the hair and started slapping me, and then choking me until I gasped for air. He claimed it was because I hadn't done the laundry." — Marie Claire, Sept. 26, 2016

3. Mohamed Lahouaiej-Bouhlel, who murdered 86 people with a truck at a Bastille Day celebration in Nice, France, had been accused of spousal abuse.

"Police responding to the distress call said they arrived to find the couple in a car in front of the house. The officers say they approached Tsarnaev, who stepped out of the vehicle and told them the woman had been 'yelling at him because of another girl.' 'I asked the suspect if he had hit the victim, and he said "Yes, I slapped her,"' the Cambridge officer wrote in the report." — ABC News, April 22, 2013

12. Before killing three of his wife's co-workers in Wisconsin in 2012, Radcliffe Franklin Haughton had been exhibiting violent and controlling behavior toward his wife.

"A man suspected of opening fire at a Wisconsin salon where his wife worked, killing three women and wounding four others, had a history of domestic abuse and had been arrested for slashing his wife's tires a few weeks earlier, police said." — San Diego Union-Tribune, Oct. 22, 2012

It's time to take domestic violence seriously — both as a public and social health crisis.

Attacks on intimate partners and family members have a nasty habit of leading to much, much worse.

In an age where mass shootings and terror attacks are proliferating, encourage your lawmakers and local law enforcement to enforce prohibitions against those convicted of domestic violence owning deadly firearms.

If someone you know is being abused, it may not benefit them to go to the police right away. Instead, experts recommend, ask the victim what they need, keep a journal of events, and when the time is right, help them create a safety plan where you can communicate discreetly.

You can also reach out to the National Domestic Violence Hotline for help.

It might just save more than one life.
