A TWISTED teen used a dating app to lure a man on a first date before plunging a knife in his neck within minutes.
The 19-year-old, named only as Sarah M due to Germany’s strict privacy laws, idolised American serial killers Richard Ramirez and Ted Bundy and hung posters of both on her bedroom wall.
A court heard how she had bought the murder weapon - a camping knife - five days before the attack in May 2021.
She set up a fake dating profile using the name Domina Cherry and started talking to Zeyed E.
That same day, the 38-year-old victim picked Sarah M up from her apartment in Bavaria and as they drove along, she stabbed him in the neck.
He was able to snatch the knife from her and stop his car on the main road.
However, he fell into a coma and died of his injuries in hospital three weeks later.
A bloodied Sarah M was arrested in the nearby town of Ebermannstadt within an hour.
On the night of the murder, Sarah M even sent a voice message to a friend saying “I'm going out now, I want to kill my first one. I'm excited. Wish me luck that it works."
And as she was handed a 12-year sentence in a socio-therapeutic facility for the murder, she responded by holding up her left palm where she had scrawled a pentagram – a symbol often used by Satanists.
The judge said Sarah M had shown "a complete lack of empathy" for her victim - highlighting how before the murder she had researched online where to stab a person in the neck and how long it would take to die.
“It is extremely rare for a perpetrator to kill a person out of lust for murder," the judge said.
Before the murder, Sarah M had suffered drug problems and had drawn swastikas - an illegal symbol in Germany - on her hands.
She had also been in and out of court since 2017. She once received a community service sentence after calling police officers “b*****ds” and “sons of bitches”.
Just two months before the murder, the Bamberg mental hospital diagnosed her with borderline syndrome and strong suicidal thoughts.
Defence lawyer for Sarah M, Thomas Drehsen, had asked for a juvenile sentence of just eight years, given that she was only 18 at the time of the murder.
He said the killing had been “blundering”, and that Sarah M was by no means in the same league as the serial killers she adored.
However, judge Manfred Schmidt ruled that the nature of the crime, and the killer’s apparent lack of remorse meant there was a “special gravity” of guilty at play.
The teenage killer was besotted with infamous US serial murderers such as Ted Bundy and Richard Ramirez.
Ramirez, also nicknamed “The Nightstalker”, was convicted for 13 gruesome and brutal murders between 1984 and 1985.
He used machetes, hammers, knives and guns to murder people - ranging from nine-year-old children to 83-year-old pensioners, and raped at least eleven of his victims.
The serial killer also made them swear allegiance to Satan before he slaughtered them, and left pentagrams at scene.
At his first trial date on the first day of his trial on 22 July 1988, he yelled "Hail Satan", and later held aloft his left palm where he had scrawled a pentagram symbol.
