Robert Fassnacht

[5] Fassnacht was survived by his wife, Stephanie, and their three children: a three-year-old son, Christopher; and twin daughters, Heidi and Karin who turned one a month after their father's death.

On May 18, 2007, the University of Wisconsin–Madison unveiled a plaque on the side of Sterling Hall commemorating the bombing and Robert Fassnacht's death.
