On 27 February 2000, three American teenagers threw rocks from a pedestrian bridge at vehicles moving on the B3 motorway in Darmstadt, Germany. The rocks struck six cars, killing two women, 41-year-old Katrin Rothermel and 20-year-old Sandra Ottmann, and injuring 17 others. The perpetrators, aged 14, 17, and 18 at the time of the attacks, were the children of U.S. Army soldiers stationed nearby. In December 2000, all three were convicted of first-degree murder in a German court and given sentences ranging from 7 to 8-and-a-half years in prison. After serving half of their sentences, the three were released early on good behavior and returned to the United States.
