There is a DNA trace and a blanket for comparison to the piece in which Sonja Engelbrecht's body was wrapped in 1995.
The police are once again going public with their investigation into this murder case.
In the case of "Aktenzeichen XY... unsolved", former owners of these are wanted.
Who is Sonja Engelbrecht's killer?
For a long time it looked as if there would never be an answer to this question.
Now, almost 28 years after the disappearance of the then 19-year-old from Munich, the homicide investigations are in full swing again.
This Wednesday, the case will again be a topic on the TV show "Aktenzeichen XY... unsolved" (ZDF, 8:15 p.m.).
Just three weeks after investigators last addressed the public.
With good reason, as homicide chief Stephan Beer explained at a press event.
Because: After the file number broadcast on March 1, 280 tips were received by the police.
"These included 40 new investigation tracks," explains Beer - tracks to specific people.
And clues to the remains of a blanket
which were found together with the mortal remains of Sonja Engelbrecht in 2022 in a remote wooded area near Kipfenberg.
"The ceiling is the breakthrough," emphasizes the chief investigator.
40 new investigation leads
On TV, viewers were asked to get in touch if someone owned a comparable piece.
Two hours after the broadcast, a woman actually picked up the phone.
Your blanket, which Beer presented to the media on Tuesday, will also be important on Wednesday's show.
"Does anyone know someone who owned a blanket like this before 1995?" will be one of the questions.
Just like the question about a person who was busy with renovation work in Kipfenberg in 1994 or 1995.
Because: According to Beer, white wall paint stuck to the plastic foil and adhesive tape in which Sonja's remains were wrapped.
As the chief investigator confirmed, DNA traces were also found on the materials in the forest.
50 people from the Kipfenberg area were asked to take a DNA test last summer and autumn.
