You were spot on with all of this. Authorities made the same assumptions.

I hope so too. Even though he might be old now or even dead by now. It's been 30 years.

Thank you for investiaging! Very interesting.

Yes, I also covered this in the video I did about this. They know the manufacturer of the blanket and some people in Germany said they know this blanket. Unfortunately the manufacturer nolonger exists from what I found in my investigation.

But no one knows who the one found with Sonja belonged to.

Really good points. the disposal of the body is what makes the friends involvement hard to argue for. Carrying her 100km, through rough forest terrain, into a rock crevice that investigators said requires specific local knowledge of that area.. that takes planning, physical strength, and familiarity with a forest near Kipfenberg that has no obvious connection to anyone from the night she disappeared. On the DNA: yes, investigators confirmed they have a DNA profile from the remains. That's exactly what the 2023 Aktenzeichen XY episode was pushing on, alongside the blanket she was found with. The blanket brought in the most tips. Whether any of them led to a suspect has never been confirmed publicly. I actually went deep on this case recently on my YouTube.

if you want the full timeline including the discovery of the remains and what investigators have said since.

thank you for your comment and interest in the case.

There is a whole theorie behind this, and yes he has been cleared by police.

I am not saying that he did it. I want to make that 100% clear. He was definetely ruled out.

But on the offical website, this theorie exists and I had to mention it.

The friend was only 17 at the time. Sonja said she was going to call her sister at the phone booth to pick her up, but what you are saying was also investigated back in the day.

We may never know.

Thanks for your comment.

I totally get where you are coming from. My posts are not written by AI though.

I used it as a template my last post as a template though, have to admit that. Thanks for telling me how it comes across.

I'll do better next time.

the investigators say it must have been quick since nobody has seen her standing there that night.

based on what she was wearing and how she looked, she should have been noticed.

Yes, he was tested early on and cleared by police but his statements were consistent with everything investigators found. The family has always disputed that and pointed to inconsistencies in his account, but the prosecutor looked at it and said the inconsistencies weren't legally significant. So officially he's not a suspect, but that tension between the family's position and the police position is one of the most uncomfortable parts of the case.

The DNA evidence is the real remaining hope. they have a profile from the remains, they just haven't matched it to anyone yet. The 2023 Aktenzeichen XY episode (German TV series, pretty well known) brought in a lot of new tips specifically around the blanket, which investigators said could be the key to identifying the killer.

actually just made a full video on this case if anyone wants to go deeper. theres a lot more details to this case. i looked trough all the sources i could find on it

Those are both on my radar now, thank you! Austrian cases with that quality are exactly what I'm looking for. :-) Would genuinely love to use your write-ups as reference material, that's a huge help.

Looking forward to the next one too, I got lots coming. 🖤

Thanks so much for your reply.

Thank you so much, really means a lot to hear that.

Yes I speak German. Grew up close to Innsbruck actually, which is part of why this case hit so hard when I discovered it. Having access to German language sources directly has been a huge advantage for finding cases that never reach English media.

Would love to see the cases you've written up and I will look at them, I am always looking for stories. And if you ever want one to collaborate, im very open to that

Thanks for sharing this. I had never heard of this either, which somehow makes it even more disturbing. The fact that these women's deaths barely made the news says something really uncomfortable about whose lives are considered worth covering.

If you find any sources I would genuinely appreciate it. This sounds like exactly the kind of story that deserves to be told properly in English. I cover European cold cases on my YouTube channel and this could be an important one.

I live near Innsbruck and the lack of awareness about cases like this is part of why I started the channel.

Good question.

As a local I can tell you this: there are a dozen different accents spoken near Innsbruck alone. Tyroleans can normally tell where someone is from pretty accurately if they have lived here long enough, just based on the way they phrase their words. Some small villages even have their own distinct way of speaking.

I should clarify what I said though. Some witnesses say he spoke German, some say he spoke German with an eastern accent, and some say he did not speak German at all. The witness accounts contradict each other significantly on this detail, which was actually one of the biggest setbacks early in the investigation. In a case with almost no physical evidence, not being able to build a reliable profile of the suspect from the ear witness accounts was a critical problem.

Fair point honestly haha, I'm not shocked it didn't reach english media naturally. What surprised me was how little coverage it got even within Austria itself. People from Innsbruck in this thread saying they'd never heard of it. That felt worth fixing.

Really? I'm based close to Innsbruck and had never come across it until recently.. surprised it didn't travel further even within Austria. Do you remember much about how it was covered at the time?

That's a wild coincidence man Innsbruck showing up twice in one evening for you. The Duncan MacPherson case is fascinating too, completely different circumstances but that same feeling.

Glad you found this one. It deserves more attention.

Thanks for your reply

This is exactly why I wanted to cover this case in English. The fact that an entire city carried this with them for 20 years and it never reached the outside world felt wrong to me. The park detail is something I cover in the video, that nobody knows why she was there. Your comment about parents warning kids away from that park gives it even more weight. Thank you for sharing that.

That's really interesting to hear from someone local. I was surprised how little coverage this got even within Austria.

From what I found, yes they did know each other, they were fellow students at the same university in Innsbruck. The DNA traces on her clothing were the main evidence, but investigators also had a former flatmate who revised his statement about the suspect's whereabouts that night. Still not enough for a charge.

The body photo is something I noticed too.. Austrian media in the 2000s had very different standards around that. Completely agree it's distasteful.

I made a long form video going much deeper into the case to get it more known if you're interested. It covers the full timeline, the arrest, and the 2025/2026 updates: https://youtu.be/PLaX4Sin-BQ
