Firefighters battling an 18,000-acre wildfire in the Angeles National Forest gained better control over the blaze Friday as cooler temperatures prevailed.

Investigators now believe the fire was caused by someone practicing an animal sacrifice ritual. The fire was 25 percent contained Friday.

Some 50 vacation cabins have been destroyed by the blaze.

Meanwhile about 40 miles away near Leona Valley a 5,100-acre fire that had threatened 100 homes was brought nearly completely under control. That fire destroyed four homes earlier this week.
