The occurred on July 14, 2003 close to Karlsruhe, Germany, when a young mother lost control of her car and collided with a tree. The 21-year-old woman and her two-year-old daughter died at the scene. The accident and the following judicial proceeding received nationwide attention after eyewitnesses stated that another vehicle had closed the gap to her from behind with excessive speed and caused the accident. The case was known in the media as "Autobahnraser-Fall" (motorway speeder case) and sparked a debate about a general speed limit on German motorways which doesn't exist at the present.
On July 14, 2003 around 6 a.m., a 21-year-old woman was travelling with her two-year-old daughter on the Autobahn 5 from Karlsruhe in direction to Frankfurt am Main. A short distance before Bruchsal, she lost control of her car, a small Kia, left the road to the right and crashed into trees behind the traffic barrier. Although the Autobahnpolizei, paramedics, an emergency physician and Feuerwehr arrived shortly after, they were not able to rescue the victims because both had died instantly as a result of the collision. Eyewitnesses driving in the same direction reported to police that a dark coloured vehicle, possibly a Mercedes-Benz, had approached the woman's subcompact car with high speed without keeping any safety distance, which is mandatory in Germany at higher speeds. Expert evidence later stated this was causal for the woman's driving mistake, as she likely jerked her steering wheel in panic, trying to avoid a rear-end collision.
A police task force with 42 members was formed and concentrated their search on a dark coloured Mercedes-Benz sedan or coupe, based on the witnesses declarations. A 34-year-old Mercedes-Benz test driver, Rolf Fischer, became suspect soon when it turned out he used the Autobahn 5 around the same time that morning with his dark blue Mercedes-Benz_CL-Class - among his colleagues, he was known as "Turbo-Rolf" for his fast driving. Although he denied being involved in the accident, the prosecutors office brought charges against him because of reliable observations from witnesses with car-related knowledge, who recognized noticeable parts of the test car like the headlights and exhaust pipes.
Rolf F. was found guilty in two levels of jurisdiction for reckless driving in coincidence with involuntary manslaughter. Additional to the witness testimonies regarding his car, he made wrong statements about his departure time at home and gas station voucher showed, he could have been at the scene of the accident at the relevant time. His behaviour towards colleagues from work in the time after the accident had also raised suspicion in the company, that he could have been aware of the fact that he was in some way involved in the accident. The Local District Court in Karlsruhe sentenced Rolf F. to 18 months in prison without parole on February 16, 2004. His driving license had already been revoked when he became suspect of police investigations.
