A 38-year-old laborer hanged himself in his home in the village of Hortiatis, near Thessaloniki, yesterday after strangling his 36-year-old wife and attacking his 8-year-old son following a dispute about the family’s debts. Police said the man killed his wife with a length of cable following an argument about outstanding mortgage payments. He also tried to strangle his son but was stopped by his 15-year-old daughter. He then hanged himself with the same cable. The children were both unhurt. In another incident in Menidi, north of Athens, on Monday night, a 53-year-old Kazakh man shot his 57-year-old sister in the spine following a dispute about money. The woman was hospitalized in critical condition. Police surrounded the man’s home and dispatched a psychologist to talk him round. But shortly before 4 p.m. yesterday, the 57-year-old shot himself in the head.
