Alameda Co. officials investigate fire that burned 2 homes

Alameda (KGO) -- Alameda County officials are investigating the cause of a two-alarm fire that ripped through two homes on Sunday.

A homeowner on Norwich Road says he barbequed for dinner Saturday night, shortly before hearing an explosion, then saw the flames.

He thinks the grease burning on the hood of the barbeque may have ignited the flames.

Neighbors looked on as firefighters worked to put out the fire.

Residents inside both homes got out safely and are now staying with relatives or friends.
