An Austrian man killed his parents-in-law by setting them on fire with a homemade flame-thrower.
The 48-year-old man used a flame-thrower he had created from a propane gas container to set alight the elderly couple as they lay in bed.
The woman burned to death in her bed and her husband's body was found on a bench outside their home in the southeastern village of St Magdalena am Lemberg.
The man fled the scene and stabbed himself in the stomach. He is now in an induced coma following an emergency operation.
