A fire that started in a garage Saturday afternoon at 319 Northwood Lane caused an estimated $33,000 in damage to a duplex, said Division Chief Eve Tolefree, a Lawrence-Douglas County Fire Medical spokeswoman.

A preliminary investigation indicated it started after charcoal briquettes weren’t discarded properly. A family of four who lived on one side of the duplex is staying with family days after the fire.

Tolefree said a separate fire in northern Lawrence that started earlier Saturday at 1403 W. Second Terrace caused an estimated $26,000 in damage. That fire damaged the exterior of a home on the property. Its cause is officially undetermined, she said.
