Daimler CEO Dieter Zetsche

Daimler CEO Dieter Zetsche is being investigated for involuntary manslaughter after a 27-year-old engineer was killed in a test track accident caused by an intern. Apparently, the intern somehow wound up with the keys to an unspecified fast car, and things turned sour.

Daimler says the investigation is a "formality," and that a judge has already decided that Daimler can't be held liable. The investigation came after the parents of the dead engineer said that Daimler had no business putting an intern behind the wheel.

*UPDATE: According to Reuters, German public prosecutors have just announced that they are dropping pursuit of involuntary manslaughter chargers for Zetsche.
