If this is not the right place, please let me know.
So one of my relative reach out to me, she is looking her cousin. According to her, he wasn't really in good relation with his main family. However since he is barely contacting anyone except his only cousin, nobody really notice that he is cutting contact or missing. Nobody knows.
She was here a week ago and reported to the police. The police didn't want to take further action, since it is already too long. He doesn't register to the embassy or consulat either, the uni refuse to give information. So basically deadend. I try to help them use any connection i got, student groups especially for Indonesian. And also my friends that live around Frankfurt and so. And this is on reddit. Maybe someone here has seen him or study with him on the same major. Whatever info you have regardless how it will helps or not. Thank you.
This is the main post from my relative.
Hello, Everyone!
We would like to ask for your help. If you have any relatives or friends living in Germany, we would be very grateful if you could help share the missing person Facebook link above.
Our cousin, Russell Koyean, a 34-year-old man, has been out of contact with his family for over a year. The last time he was in contact with his family was in August 2025.
Russell was last known to be pursuing his Master's degree in Biomedicine at the Technical University of Munich (TUM) in Munich, Germany.
Our family's only wish is to know that he is still alive and doing well.
The family has made every effort to find him, including contacting the German police and the Indonesian Consulate General (KJRI) in Frankfurt.
We have also contacted TUM. However, the university has been unable to provide us with any information about whether Russell is still studying there or when he last attended.
If you have any information about Russell or knew him while he was in Germany, please kindly contact our family using the numbers below:
📞 Merria: +1 405-388-3190
📞 Sherly: +62 878-8157-8298
📞 Vanessa: +61 457 094 809
📞 Murni: +62 812-1088-165
Any information, no matter how small, would mean a great deal to our family.
We sincerely appreciate your kindness and help in sharing this post. Thank you so much for your support and prayers. 🙏
