The man who killed 16-year-old au pair Lucie Trezzini in 2009 has been sentenced to 20 years in prison.

The 28-year-old killer lured her to his flat by telling her he was looking for girls to model jewellery.

The man confessed to the killing several days later saying he wanted to return to prison. He had previously tried to kill another young woman in 2003 and spent four years in a rehabilitation centre.

While prosecutors had called for him to spend life behind bars, the defence lawyer called for a reduced sentence and for him to receive medical care.

The accused said several times during the trial he regretted the act, which the prosecutor said was a tactic.

In handing down the sentence, the presiding judge at the court in Baden said the accused had acted “unscrupulously”, and that a "young human being had been snatched from life in a horrific manner".

Around 1,000 people attended Trezzini’s funeral after her case made headlines nationwide.
