Sacramento firefighters say a man has been seriously injured after starting a house fire while apparently burning his divorce papers.

Sacramento Fire Department Capt. Jim Doucette says the man lived with his father, who says his son was distraught. The father tells firefighters his son had been lighting things on fire all night Friday. The fire began Saturday morning when the man set his divorce papers aflame.

The fire damaged the two-story duplex in Sacramento's West Natomas area. It sent the man to a Sacramento hospital with serious injuries including smoke inhalation. He was not being named.

Doucette says the fire was in an upstairs bedroom where the man also was found. Two cats were also found dead of smoke inhalation.
