Oral Sex Robber Leaves Behind DNA Tying Him To Murder Of Swiss Woman Millionaire Over 20 Years Ago

A 78-year-old Italian man who killed an elderly millionaire widow in 1997 has been caught and jailed after he carried out an armed robbery almost two decades later where he forced the daughter of his victims to perform oral sex on him, leaving behind DNA that tied him to the earlier murder.

Swiss cops caught up with the suspect more than two decades after the murder when his DNA was found at the scene of the violent robbery of a Swiss jeweller, and matched with the older crime.

A court in the Kusnacht municipality near Zurich, Switzerland, has now sentenced the man, named only as Carlo F. due to strict local privacy laws, to 13 years behind bars for killing the then 87-year-old millionaire, named only as E.C., in her villa in the Swiss municipality of Kusnacht 24 years ago.

The case had been suspended by Swiss authorities in 2001 after the investigators failed to arrest any suspects.

However, the Italian national returned to Switzerland in November 2016 and carried out a robbery at a jewellery shop in the town of Thun, in the Swiss canton of Bern, where DNA traces were then secured by the police.

During the robbery, for which he was later convicted, he threatened the shop owners with a fake gun and forced them to hand over jewellery worth CHF 100,000 (GBP 81,000).

He also reportedly forced their underage daughter to perform oral sex on him.

The DNA traces at the Kusnacht and Thun crime scenes matched, and the suspect was later identified as Carlo F., 78.

He was arrested in the municipality of Arona in Tenerife, in the Spanish Canary Islands, in 2017 and was extradited to Switzerland to face charges for the Thun robbery.

In 2018, he was sentenced to seven years in prison in the Swiss canton of Bern for multiple robberies, deprivation of liberty, hostage-taking and sexual assault, among other charges.

While serving his sentence, the investigation into the 1997 murder case was completed and his trial began.

The court heard that a then 54-year-old Carlo F. had broken into the rich widow’s house, beat her, and then tied her up.

The victim was tied up in a position that would have caused her excruciating pain for several hours before she eventually died of acute heart failure, reported Blick.

The suspect denied the accusations and explained the DNA traces by claiming that the elderly woman had been paying him to participate in a sadomasochistic sexual relationship. The court dismissed the alibi as “absurd”.

The suspect showed no remorse or intention to cooperate with the authorities but his sentence of 13 years for the murder may be reduced due to his advanced age and poor health.

The sentence is not yet binding, as the suspect is expected to appeal the ruling.
