No one injured in Grayslake house fire

A single-family home in Grayslake is uninhabitable after a fire Saturday afternoon destroyed much of the interior.

Grayslake Fire Protection District Lt. David Torkilsen said nobody was in the house when the fire started at about 3:17 p.m. on the 33000 block of North Lone Rock.

The blaze apparently began in the rear of the ranch home, but Torkilsen said the cause is unknown. Investigators said it caused an estimated $150,000 in damage.

Crews had the fire under control in about a half-hour, Torkilsen said.

The Gurnee, Round Lake, Fox Lake, Libertyville and Waukegan fire departments assisted at the scene, while the Mundelein and Wauconda fire departments stood watch over the Grayslake fire station.
