Yasin Friese was a young, deaf child in 2019 and "boyfriend" of Elisabeth Doppler.
He and Elisabeth are seen chatting with one another after school on November 6, 2019, the day of Elisabeth's disappearance. Yasin's mother had offered to drive her home, but Elisabeth declined, expecting her mother at any minute.The next morning, walking to school alone through the forest, he encountered a hooded figure, and disappeared. He was reported missing the next morning, becoming the subject of yet another Winden Police investigation.
He and Erik Obendorf, kidnapped on October 22, are found buried in a pile of sand at the nuclear plant construction site on November 10th, 1953. Both had been killed by Noah's experiments on time travel in the bunker using the chair, and their bodies subsequently moved to a place where they would be discovered in 1953 by the 1986 Helge Doppler.
The name Friese is derived from the Frieseland region, abutting the North Sea; thus, like Nielsen and Tiedemann, it has a northern origin. Yasin is a name derived from the 36th surah of the Qur'an, which starts with these letters, as well as one of the names of the Prophet Muhammad.
Yasin may be of Turkish descent, at least in part. When the 1953 police pathologist, Udo Meier, examines Yasin's body, he comments that the boy must not be local, because he looks Mediterranean. While Germany today has a significant ethnic Turkish population of around 5 percent, this is due to a large influx starting in the 1960s with a guest worker program, intensifying in the 1970s after reforms to family reunification laws.
