Posted by On the night of 26 October 1984 Günther Stoll, a German food engineer, was found naked and badly injured in his car beside the A45 motorway near Hagen. A few hours earlier he had written a meaningless word on a sheet of paper: YOGTZE. For forty years it was treated as an unsolved murder. In 2025 police closed the case: a road accident.
This is one of those cases that mystery lovers know by heart. An incomprehensible word, a man shouting “now I’ve got it!”, a night on the motorway, four unknown men who may or may not have been there. And an ending that, when it finally came, disappointed many. But I think it deserves to be told this way too.
“Now I’ve got it!”
In 1984 Günther Stoll was 34, lived in Anzhausen, Westphalia, and was an unemployed food engineer. For some time he had been telling his wife he felt threatened by “them”, unknown people who wanted to hurt him.
On the evening of 25 October, at around eleven, he spoke about “them” again. Then suddenly he exclaimed: “Jetzt geht mir ein Licht auf!” – now I’ve got it. He grabbed a sheet of paper, wrote six characters, YOG’TZE (or perhaps YO6’TZE), and immediately crossed them out. Then he left the house.
The night
He went to his favourite pub, the Papillon in Wilnsdorf, and ordered a beer. Shortly afterwards he collapsed and injured his face. Witnesses insisted he was not drunk. He got up and drove off in his Volkswagen Golf. Nothing is known of the next two hours.
At around one in the morning he arrived in Haigerseelbach, the village where he grew up, and knocked on the door of a woman he had known since childhood. He told her about “a horrible incident that was about to take place that night”. She suggested he go to his parents, but he said they would not understand him. In the end he agreed to go home to his wife.
The A45
At three in the morning two lorry drivers found his Golf in a ditch beside the A45, near the Hagen-Süd exit, about a hundred kilometres from Haigerseelbach. Both said they had seen an injured person in a white jacket walking near the car. Inside, in the passenger seat, was Stoll: naked, badly hurt, still conscious.
He said four men had been in the car with him and had run away. Asked whether they were his friends, he said no. He died on the way to hospital.
Murder?
The first investigation seemed to confirm the worst. According to experts, Stoll had been injured before the crash, perhaps run over by a car somewhere else while already naked, then placed in the passenger seat and driven to the spot. The man in the white jacket and a hitchhiker seen at the Hagen-Süd exit were never identified. Rumoured contacts with drug dealers in the Netherlands were also investigated, with no result.
And the note? It was gone. His wife had thrown it away that very night, thinking it unimportant. So nobody can confirm what it actually said. When the case was shown in 1985 on the German TV programme “Aktenzeichen XY… ungelöst”, tips poured in: some radio amateurs, for instance, pointed out that replacing the G with a 6 gave the call sign of a Romanian radio station. None of the theories led anywhere.
The answer, forty years later
In April 2025 Hagen police and prosecutors announced that the YOGTZE case was closed. Using a reconstruction and two new expert reports, they concluded that the injuries did not match being run over, but a crash: Stoll was not wearing a seatbelt, the car left the road and hit trees, and the impact threw him onto the passenger seat. No DNA from anyone else was found in the car.
According to investigators, Stoll suffered from depression and was probably going through a severe psychological crisis that night, which would explain his behaviour, his nakedness and his story of unknown men. The official conclusion: a single-vehicle accident with no third-party involvement. As for the note, investigators doubt it was ever relevant.
I know many enthusiasts were disappointed by this answer, and I partly understand why. But the more I think about it, the more it seems the saddest version of all: not a conspiracy, not a gang of killers, but a man who was unwell, who asked for help that night in his own way, and whom nobody managed to stop. YOGTZE may have meant nothing. He did.
