Adelaide family escapes suspicious blaze AN Adelaide family has escaped a fire that destroyed their home, and which police say was deliberately lit. The two adults and five children fled their Christie Downs house just after 2.30am (CST) on Sunday, as the fire quickly engulfed the building. Fire investigators say a mattress which was leaning against the house was set alight. A Metropolitan Fire Service (MFS) spokeswoman said the family was alerted by a smoke alarm, but their home was completely destroyed. The damage is estimated at $150,000. "Unfortunately the occupants do not have any insurance," she said.
