Marco Bergamo (serial killer)

Italian serial killer

Marco Bergamo (6 August 1966 – 17 October 2017), known as The Monster of Bolzano, was an Italian serial killer who murdered five women between 1985 and 1992.

Biography

Ever since childhood, Bergamo lived with complications: at the age of 4, he stuttered, and later on was obese and suffering from a skin disease, turning him into a shy introvert. He subsequently collected numerous items, including knives — and always carried a knife.

After starting work as a welder and carpenter, at the age of 26, in May 1992, he underwent surgery to remove one of his testicles.

Murders

Bergamo murdered five women between 1985 and 1992, including a 14-year-old student and four prostitutes, the eldest of whom was 41.^[1]

On 3 January 1985, the first victim, Marcella Casagrande, a 15-year-old first-year student of the nearby Magistral Institute, was found dead in her home. Casagrande had been murdered using a knife with which the killer had good knowledge of using, as well as equally good knowledg

15 Notorious Serial Killers and Their Chilling Crimes

Elizabeth Báthory

1560-1614

Although the true extent of Elizabeth Báthory’s crimes is debated, she now holds the dreadful nickname of the “Blood Countess.” A wealthy Hungarian noblewoman, Báthory was believed to have tortured or killed scores of female servants and minor noblewomen prior to her 1610 arrest.

Although she wasn’t convicted of a crime—and much of her alleged blood lust stems from questionable witness testimony—the Guinness Book of World Records cites Bathory as the most prolific female murderer in history with 600 victims. Báthory might have even helped inspire Bram Stoker’s 1897 vampire novel Dracula.

Belle Gunness

1859-c. 1930

Almost as shocking as Belle Gunness’ reported crimes—authorities found the remains of more than 40 victims on her property in 1908—was her unsolved disappearance.

Born Brynhild Paulsdatter Strseth in Norway, Gunness moved to the United States in 1881. She was soon connected to several mysterious deaths, including those of two h

Are murderers born or made?

A breakthrough came in 1993 with a family in the Netherlands where all the men had a history of violence. Fifteen years of painstaking research revealed that they all lacked the same gene.

This gene produces an enzyme called MAOA, which regulates the levels of neurotransmitters involved in impulse control. It turns out that if you lack the MAOA gene or have the low-activity variant you are predisposed to violence. This variant became known as the warrior gene.

About 30% of men have this so-called warrior gene, but whether the gene is triggered or not depends crucially on what happens to you in childhood.

Jim Fallon, professor of psychiatry at the University of California, has a particularly personal interest in this research. After discovering a surprisingly large number of murderers in his family tree he had himself genetically tested and discovered he had an awful lot of genes that have been linked to violent psychopathic behaviour.

As he puts it: "People with far less dangerous genetics become killers and are psychopaths than what I have
