Devastated by the death of his wife and two children aboard flight 2937, Vitaly Kaloyev, a Russian architect, held Peter Nielsen personally responsible for their deaths. He tracked down and stabbed Nielsen to death, in the presence of Nielsen's wife and three children, at his home in Kloten, near Zürich, on 24 February 2004. The Swiss police arrested Kaloyev at a local motel shortly afterward, and in 2005, he was sentenced to eight years for manslaughter. However, his sentence was later reduced after a Swiss judge ruled that he had acted with diminished responsibility.
