Flames from a structure fire near the Viejas Casino and Resort spread to brush in East County overnight, prompting a large response from firefighters.
Crews were called to a two-story abandoned home on Viejas Grade Road north of Interstate 8 and east of Alpine after 2 a.m. and, upon arrival, called for backup.
Firefighters with Heartland, Santee, Viejas, Cal Fire and San Diego fire departments worked to control the large flames that were shooting from the home.
Alpine Sheriff's department as well as tribal security also assisted at the scene.
Once the blaze was out, crews remained at the scene for several hours to mop up the fire and ensure hot spots didn't flare up.
The cause of the fire remains under investigation.
