Austrian police say a man set his wife's parents on fire with a home-made flame thrower, killing them.
Chief investigator Anton Kiesl says the 48-year-old man set the elderly couple on fire as they lay in bed late Friday using a flame thrower he made from a propane gas container.
Kiesl said the woman burned to death in her bed and her husband's body was found on a bench outside their home in St. Magdalena am Lemberg in the southeast.
Both victims were in their 80s; the woman was bedridden.
Kiesl said Saturday the man fled and attempted to commit suicide by stabbing himself in the stomach. He is currently in an induced coma.
