Marco Bergamo was born in 1966 and worked as a welder in Bolzano, in the German-speaking province of Alto Adige in northern Italy. The Italian press called him il mostro di Bolzano, the monster of Bolzano; his surname and the Lombard city of Bergamo are a coincidence, and the killings were in Bolzano and the surrounding province.
Between 1985 and 1992 he killed five women and girls: Marcella Casagrande, fifteen; Annamaria Cipolletti, forty; Renate Rauch, twenty-four; Renate Troger, eighteen; and Marika Zoller. He stabbed them, in most cases many times, in parks and on paths at night. Several were working as prostitutes and some were not. The fifth was Marika Zorzi, eighteen.
He was arrested and convicted, and sentenced to life imprisonment in 1994. He confessed to four of the killings.
The case is notable in Italy for the length of the gap between the first and last murders in a small city, and for the fact that Bolzano's German- and Italian-speaking communities followed it in separate newspapers with different emphases. The accessible sourcing is Italian-language summary material and is not detailed on the investigation.
On the sentence: Italian life imprisonment is reviewable rather than whole-life, with conditional release capable of being considered after twenty-six years. Nothing accessible records whether he has applied or where he is now.
