Still Waiting for Cause of Fatal Fire

State police fire marshals are waiting for laboratory results before they can determine the cause of a Jefferson County house fire that killed 10 people. Police spokesman Bruce Morris says they don't know how long it will take for results to be made available to the fire marshals investigating the April 3 blaze in Brockway. Investigators say the fire, which began in the living room, isn't suspicious. Space heaters were being used and gas service had been shut off in 2005.
