More than 200 people gathered March 8 at Graham Chapel at Washington University to hear Andrew Rehfeld, president and CEO of Jewish Federation of St. Louis, and Tarek El Messidi, founding director of Celebrate Mercy, a Muslim advocacy organization, discuss the response to the cemetery vandalism and how the Jewish and Muslim communities can continue to work together. The two organizations raised several hundred thousand dollars to help Chesed Shel Emeth Jewish cemetery make repairs to the 154 damaged headstones and upgrade its security.
