The middle-class background of German schoolgirl killers is revealed when a TikTok video emerges of their 12-year-old victim having fun with one of their killers before getting into an argument “into harassment”.

It’s the murdered German schoolgirl Luise Frisch who appears in a TikTok video with one of the classmates accused of killing her.

12-year-old Luise was found stabbed multiple times in a remote forest in a crime that shocked Germany after her attackers were revealed at the same age.

Initially, two girls, aged 12 and 13, denied any involvement, but the couple eventually confessed after police found inconsistencies in their stories.

The video – which has been reposted thousands of times on social media – shows Luise and the 13-year-old girl wearing soft drinks and masks due to local Covid lockdown laws when it was filmed.

All three girls went to the same class at the Esther-Bejarano-Gymnasium in Freudenberg near Cologne and were dubbed “best friends” in another shocking twist.

In another shocking development, it emerged the 13-year-old posted a video on TikTok of her dancing just hours after Luise’s tragic body was found on March 12 – a day after she was listed as missing by her worried parents has been reported.

Because of the age of those involved, police and prosecutors have released few details and possible motives include a TikTok spat, rivalry over a boy and revenge after Luise claimed she was bullied at school.

Both suspects – who are of middle-class origins – and their families have been handed over by the authorities and will not face criminal charges in Germany as they are under 14 years old.

The father of the 12-year-old suspect works at a local bank and is treasurer of the village band, where he plays the bugle.

The family lives in a large two-storey house on the outskirts of Freudenberg, where Luise spent the night before her murder after an overnight stay.

The girl lived there with her parents, grandfather and two siblings, and neighbors are shocked by the tragic events.

A notice on the door told the media to stay away, and a police car drove past the house regularly.

A man who ran a nearby cafe told MailOnline: “We used to see each other [the 13-year-old girl] almost every day. She was just like any other girl her age, sweet and innocent, or so we thought.

“She often came to the cafe and got food for herself and her grandfather because her parents were at work.

“It’s the age of everyone involved that shocked everyone. They are all just children. Who knows what made them do what they did, stabbing someone more than 30 times is terrible.”

The other girl (13) lived with her parents a few minutes’ drive away. Her father is apparently a firefighter and helped locate Luise after she was reported missing on March 11.

Neighbors there were stunned by the murder, one of them said: “It’s just so hard to understand. They are all just children. We haven’t seen the family for days and we don’t know if they will return.’

Although none of the girls will face criminal charges, it has emerged that they could be forced to pay damages to Luise’s grieving family as civil law kicks in at the age of seven “if they knew they were doing something harmful.” do.

Damages would be determined in a civil court and would have to be paid off once they found work, which could take up to 30 years.

Both suspects have received psychiatric help, as have their families, and they may also need to get new identities.

The German law on criminal responsibility was passed in the old Weimar Republic in 1923, but there were calls for it to be revised after the assassination.

Luise Frisch’s body was found in a wooded area near the North Rhine-Westphalian town of Freudenberg.

CDU opposition MP and lawyer Gunter Krings told MailOnline: “We urgently need to address the age of criminal responsibility in Germany.

“There needs to be a proper debate and we call on the government in power to deal with it as soon as possible. There is an urgent need for research, the applicable law is currently 100 years old.

“Children have developed rapidly over the last few decades and are more mature today than they were 50 years ago, let alone 100 years ago.

“This crime is particularly shocking given the age of the victim and the age of the suspects, and children as young as 12 or 13 are mature enough to know they shouldn’t kill.”

But Federal Justice Minister Marco Buschmann told tabloid Bild: “Crimes of this magnitude cannot remain without consequences. Any debate about changes in criminal law must be conducted coolly.

“Children over 14 will not be prosecuted. However, our justice system already has the resources to respond to serious acts of violence by children under the age of 14.”
