Cumberland County firefighters and law enforcement went to a home on the 12,000 block of Highway 70 West Saturday for a structure blaze. Crews arrived to see a detached building behind the dwelling completely engulfed in flames. The owner told deputies he was watching television when he suddenly heard several explosions. He went outside to see the garage ablaze and a driver in a brown Ford Taurus back out of his driveway and leave. The incident is under investigation.
