Multiple people dead, including kids, in shooting and fire at Montana home

A shooting and fire at a Billings, Montana, home Sunday killed multiple people, including children, authorities say.
The suspect—who later died of a self-inflicted gunshot wound—knew the victims; officials describe it as a familial disturbance, not a random attack.
Investigators are conducting a multi-day probe, have asked the public to avoid the scene, and say there is no ongoing danger.
