Serious details come to light/ The murder of the 12-year-old girl by her friends, after they stabbed her more than 30 times, posted on TikTok...

Other details have emerged regarding the serious event that happened in Germany, where two peers killed their 12-year-old friend with a knife.

According to sources from foreign media, it is known that the two minors who committed the serious act have posted a video on TikTok, where they were seen dancing after the serious event.

Allegedly, the fight between them started over a boy and led to the stabbing death of their classmate Luise.

The two schoolgirls, aged 12 and 13, reportedly stabbed their friend more than 30 times.

"How can you do that?" and "I don't believe it" are some of the comments of their classmates, below the video, about the two minor perpetrators of the crime, while some comments were also addressed to the young victim: "When your chair in the classroom was empty this morning, everyone we knew what had happened."

According to German newspaper Bild, the two girls killed her "for revenge" after the victim had told an adult that she had been molested by a boy for months.

Luise's body was found in a pool of blood on Sunday in a wooded area near the town of Freudenberg in the western state of North Rhine-Westphalia.

The shocking videos on social media were discovered during an investigation by a German WELT journalist, who discovered that one of the dance videos was posted hours after the crime.

In fact, the two girls reportedly also posted a video on Saturday (the day before she was found dead) asking for help to find Luisa as she had been "missing since 5pm", even though as it turned out, they knew exactly what had happened.

Many of the girls' classmates are said to have repeatedly reported that a boy was responsible for the wild fight between the "best friends".
