BRIGHTON, Colo. (AP) -- Firefighters say 16 horses were killed after a fire broke out in a barn north of Denver.
The fire reported just after 1 a.m. Tuesday near the city of Brighton.
Brighton Fire Rescue spokeswoman Natalie Ridderbos says the horses have various owners and that the barn appears to have been used as a boarding stable.
Firefighters don't know exactly what sparked the fire but don't believe it was intentionally set. They say it started in an area of the barn that contains a refrigerator and a light.
Another barn fire in the area killed eight horses in August. It was started by an overloaded extension cord.
