I would have thought the Israeli Olympic team members kidnapped and executed in Munich would have made the list.
Drazen Petrovic (1964-1993), a native of Sibenik, Croatia, played in the NBA for the Portland Trailblazers and the NJ Nets before being killed in a car accident in Germany at the age of 28. He also was on the 1984 and 1988 Yugoslavian Olympic teams and the 1992 Croatian team. (His father was Montenegrin and his mother Croat, according to Wikipedia.) I guess he's too much of a foreigner to be included, and hadn't played long enough in the US to be much-remembered here.
