Pisa, May 3 - A 45-year-old man, after two years without work, plunged off the sixth floor of building in Ponsacco, near the northwestern Italian city of Pisa, police said Friday. Police believe unemployment drove the laborer into deep depression and led to his suicide at the home of relatives. The man was married and lived in another town nearby. Recent studies have pointed to the recession, which is expected to last until next year, as driving a rising number of suicides in the country. A triple suicide in the Marche region in May was one of the most dramatic recent effects of the grim economic times.
