LAS VEGAS (KLAS) — A settlement has been reached between dozens of people suing the owner and operator of the Alpine Motel more than three years after a deadly fire killed six people.

In all, the global resolution involves nearly 60 plaintiffs and 18 defendants, documents the 8 News Now Investigators reviewed Wednesday indicated. Several lawsuits were consolidated into one case.

The fire on Dec. 21, 2019, ripped through the three-story motel in downtown Las Vegas, injuring more than a dozen people in addition to the six fatalities.
