The cause of a late-night Burlington house fire remains under investigation.
A man and a woman were taken to St. Elizabeth in Florence for treatment of smoke inhalation after flames broke out about 10:30 p.m. Monday inside their 5494 Carry Back Drive residence.
Initial dispatches indicate the fire started in a second floor bedroom.
Rob Butcher, assistant chief at the Burlington Fire Protection District, estimated the damage to be around $20,000 or $30,000.
Fire crews remained on scene much of the night. They finally cleared at 2 a.m.
