The teenage serial killer wannabe who stabbed her Badoo date to death had chatted to 224 other potential victims on dating platforms before she struck.

Sarah M., whose full surname was not reported due to strict local privacy laws, is on trial at the Bamberg Regional Court in the town of Bamberg in the German state of Bavaria.

The redheaded 19-year-old student is on trial for the murder of her 39-year-old Badoo date Zeyed E. from the nearby city of Nuremberg on 1st May 2021.

The victim had moved to Germany from his native Iraq in 2014 and had last worked as a security guard.

At 10.53am on the day of the crime, he messaged ‘Domina Jerry’, the name Sarah M. went by on dating platforms, for the first time.

At 8.30pm on the same day, she stabbed him in the throat with a camp knife she had bought from a DIY store.

It has now emerged that the teen had chatted to 224 men on the dating platforms Badoo and My Sugar Daddy.

Investigators say she created profiles on the two sites at 1.32am on 28th April 2021, after her boyfriend broke up with her.

She shared photos of herself dressed in lingerie on her dating profiles, on which she set her preferences to ‘BDSM’ and also described herself as bisexual and a “virgin”.

However, little did her unsuspecting online suitors know that she had a photo of her idol, American serial killer Richard Ramirez, as the lock screen image on her phone.

She also had a photo of American serial killer Ted Bundy as her background image.

Her apparent motive was revenge on her ex, whom she accused of cheating on her and of rape.

According to a WhatsApp message sent at 11.26am on 30th April, she wanted to kill “him and a few others”.

When the teen’s ex-boyfriend went to pick his belongings up from her residence, she reportedly had the camp knife at the ready under her jacket.

However, the ex had sensed the danger and had asked his friends to wait outside in their car, with instructions to break in if he failed to emerge after 10 minutes.

Thanks to the precautions he took, he did emerge, which led to Zeyed becoming Sarah’s first victim.

Investigators also revealed how the defendant had Googled how long it would take someone to die if they were stabbed in the neck or lungs.

A verdict could be reached as early as Wednesday, 9th February, according to the German daily Bild.

The defendant has so far remained silent in court.
