- Crime scene and time: B308 in the Rohrach area near Scheidegg, Friday evening, June 5, 2026, between 6:15 PM and 6:30 PM
- Course of events: plastic bags filled with oil thrown into two curves, major oil contamination, no injuries
- Investigation: police classify the case as dangerous interference with road traffic and are seeking witnesses at +49 8381 92010
The winding roads of the western Allgäu are among the popular destinations for motorcycle tours. On one of these very roads, an incident occurred in early June that revives old memories among many motorcyclists in the region. Oil ended up on the road surface of the B308 pass road in the Rohrach area, and according to police assessment, not by accident. The case falls into a broader safety issue that has concerned motorcyclists for years: deliberately placed hazards that become particularly dangerous on two wheels.
What Happened on the B308 Near Scheidegg?
On the B308 near Scheidegg, plastic bags filled with oil were thrown onto the road in two curves of the pass road on June 5, 2026. The bags burst open and caused major oil contamination. The report reached the Lindenberg police station at around 6:30 PM. According to the current state of the investigation, the incident occurred between 6:15 PM and 6:30 PM. The affected location is in the Rohrach area, a winding section in the western Allgäu. The road was closed and the fire department cleaned the road surface. No one was injured according to police, mainly because the contamination was reported in time.
How Does the Police Assess the Incident?
The police assume this was a presumably intentional act and are investigating it as dangerous interference with road traffic. The responsible authority is the Schwaben Süd/West Police Headquarters based in Kempten, the same agency that investigated a comparable case more than 15 years ago. A police spokesperson commented cautiously on possible connections. He stated: “Of course we are examining possible parallels.” At the same time he emphasized: “Due to the earlier cases, we are sensitized and are investigating in all directions.” He did not provide details about the exact nature of the bags or the oil used. He also did not comment on whether there are already witnesses or whether, as 15 years ago, a DNA trace could be secured or is being searched for.
Is There a Connection to the Oil Trail Series of 2011?
A direct connection between the incident near Scheidegg and the earlier oil trail series has not been established based on publicly available information. There is no statement so far that police or prosecutors attribute the current case to the old series. However, the geographical proximity is notable, as the new locations are less than 100 kilometers from the former crime scenes. Additionally, the officers assume an intentional act, similar to one and a half decades ago. The police are therefore examining possible parallels but are deliberately holding back on assessments.
The Fatal Case of 2011
The current incident revives memories of a fatal event on April 17, 2011, which was Palm Sunday that year. A 37-year-old motorcyclist and father of two hit an oil trail in a curve on state road 2013 between Markt Rettenbach and Ottobeuren in the Unterallgäu district. He lost control of his motorcycle, crashed into an oncoming car, and died at the scene.
Investigators determined that the oil trail had not been caused negligently but had most likely been applied intentionally. In the area, they found a total of ten oil patches, three of them directly in the vicinity of the crash site. The prosecutor’s office classified the case as intentional homicide. According to investigators at the time, the oil pools were caused by green wine bottles and clear sparkling wine bottles that had been filled with used motor oil, thrown onto the road, and shattered upon impact. The case was later also featured on the television program “Aktenzeichen XY … ungelöst” (Germany’s equivalent of “Unsolved Mysteries”).
Investigators eventually concluded this was not an isolated case. Suspicion arose that a perpetrator operating across regions could be responsible for multiple oil attacks. The known series between 2007 and 2011 extended across Bavaria and Baden-Württemberg. Cases mentioned include those near Bad Schussenried, Rennertshofen, Wittislingen, Freising, Leibertingen and Beuron, Höchstädt-Binswangen, and Schwendi. Near Rennertshofen, a motorcyclist crashed; near Wittislingen, a car driver was seriously injured. Despite extensive investigations, the perpetrator was never identified. An identical DNA trace was secured from several bottle fragments, but a comparison with the Federal Criminal Police Office database yielded no match. A DNA mass screening with more than 1,400 evaluated saliva samples also proved unsuccessful. The reward for tips was reported at more than 53,000 euros (approximately 57,000 US dollars).
Notable is how the possible perpetrator profile changed over the years. Initially, hatred toward motorcyclists was considered. Later, profilers described more of a perpetrator who sought to exercise power and bolster their self-esteem by creating fear and uncertainty.
What Parallels and Differences Are There With the Scheidegg Case?
The greatest similarity lies in the presumed intent and the choice of location, as in both cases oil was presumably applied intentionally in or near curves where it becomes particularly dangerous for motorcyclists. However, a clear difference concerns the instrument of the crime. The earlier series was characterized by used oil in wine and sparkling wine bottles and by shattered glass fragments. In Scheidegg, by contrast, plastic bags were used according to current findings. This difference argues against a premature equation of the cases. According to assessments in media reports, a copycat act or a new perpetrator with a similar approach would be equally plausible. A possible connection could only be clarified through evidence, witnesses, the instrument of the crime, the type of oil, the packaging, as well as DNA, fingerprints, or vehicle leads.
Why Are Oil Spills on Curves So Dangerous for Motorcyclists?
Oil in a curve is particularly dangerous for motorcyclists because a motorcycle has only two small contact patches with the road surface, and when leaning, a large proportion of tire grip is already needed for lateral guidance. If oil is suddenly added in this situation, the front or rear wheel can slide out without any realistic chance of reaction. The consequences range from a crash to veering into oncoming traffic to impact with a guardrail. Exactly such a sequence of events led to the fatal accident in 2011. While oil on a straight road already poses a risk, in a curve it effectively acts as a trap. Affected are not only motorcyclists but also cyclists and e-bike riders as well as car drivers who can skid.
How Should Motorcyclists Behave Now?
Motorcyclists should currently ride with particular anticipation on the B308 and similar winding roads, meaning with a far-reaching view, adapted speed, and sufficient reserves in blind curves. When encountering suspicious dark patches on the road surface, abrupt braking while leaning should be avoided. Anyone who discovers a possible oil spill should first ensure their own safety, warn other road users, and immediately contact the police or fire department.
The police are also seeking witnesses regarding the incident near Scheidegg. Anyone who observed suspicious persons, vehicles, conspicuous stopping maneuvers, or discarded bags on June 5, 2026, between 6:15 PM and 6:30 PM in the area of the B308 at the Rohrach is asked to come forward. Even small details can be important, such as vehicle color, license plate fragments, direction of travel, the exact time, or footage from dashcams and helmet cameras. Tips can be reported to the Lindenberg police station at phone number +49 8381 92010.

-
How dangerous are oil spills for motorcyclists?
Oil spills on curves are life-threatening for motorcyclists because when leaning, a large proportion of tire grip is needed for lateral guidance. If oil is added, the wheel can slide out, which led to a fatal accident in 2011.
-
Who can witnesses contact?
Tips can be reported to the Lindenberg police station at phone number +49 8381 92010. Important are observations from the time of the incident on June 5, 2026, such as vehicles, license plates, or dashcam and helmet camera footage.
