Woman, 28, strangled to death by 17-year-old because she LAUGHED at him when he failed to get an erection while they tried to have sex is pictured for the first time as her killer is jailed for nine years

A woman was strangled to death by a 17-year-old because she laughed at him when he failed to get an erection while they were trying to have sex, a court heard today. The brutal killer has been sentenced to nine years in prison.

Bianca C, 28, met Mohammed Ali S, from Tunisia, at a bar in the city of Frankfurt, Germany on October 3 last year. After a few drinks – and taking cocaine – the pair went home together.

But when they got back to Bianca’s apartment, Mohammed couldn’t get an erection. Bianca started laughing and said, “You want to, but you can’t.”

Tragically, the laughter led Mohammed to become enraged. He began to choke her until she nearly passed out, before taking out his phone to film himself punching Bianca in the face 26 times, Bild reported.

As he continued to torture her, he shouted “little slut” several times before choking her further with a belt. He eventually turned his camera back on and filmed her lifeless body as he shouted “I killed her” at 7:04am.

A witness had called the police in the middle of the night, who rushed to Bianca’s apartment.

Judge Christian Annen of the regional court in Frankfurt sentenced Mohammed today to nine years and eight months in prison for murder, just four months less than the maximum prison sentence for minors in Germany.

“The court spoke of an ‘execution-like’ nature of the crime and, because of the confession, remained four months below the maximum sentence we had demanded,” prosecutor Constanze Jung reportedly told the court.

‘We all witnessed this brutal crime, because the perpetrator had made several short films and the films were shown in the courtroom.’

The teenage killer, who had previously been convicted of sexual abuse, was arrested shortly after killing Bianca thanks to the confession he made on his phone.

He was arrested a few hours later, about six miles from Bianca’s flat. The Tunisian boy had only been living in Germany for a few years before he committed the horrific crime.

After the verdict was read, Christian Heinemann, who represented Bianca’s mother Iris (59), said that there was “no appropriate punishment for such an act, certainly not within juvenile criminal law.”

The grieving mother now has a small shrine by the front door of her home where she lights a candle every day for her deceased daughter. She lived in the apartment next door to her daughter.

After her death, she wrote in a Facebook post: “My love, my happiness, my joy, my EVERYTHING has gone to the Garden of Eden.”

Mohammed is first sent to a psychiatric institution and then to prison.
