Who pays for treating injuries after a mass shooting?

If there are survivors of a mass shooting, but the mass shooter is dead, who ends up paying for treatment of the survivors?

Is it up to each victim’s own insurance, if they have it, to cover them? Does the emergency dept/hospital absorb the costs? Is there some “victim of crimes” fund that helps offset some of the burden?

It doesn’t matter if the shooter is dead or not. I’m not aware of ANY mass murderer paying for the victims of his crimes healthcare. Treatment is paid for like any accident. There are sometimes funds for victims of crimes but that is much farther down the line.

Of course, the victims could sue the shooter (or more likely, the deceased shooter’s estate) but the payout would be more like pennies.

…it depends where you live, obviously.

In New Zealand there are various mechanisms to support victims of mass shootings. For the Christchurch Terror attacks with have Accident Compensation:

Along with other general charities and fundraising initiatives as well. Accident Compensation is generally the primary instrument used here for mass casualty events.
