On the last day of Passover, Lori Kaye went to services at Chabad Lubavitch synagogue of Poway, Calif., where she was murdered by a gunman and three others were injured.

“Coldblooded, fanatical hatred can only be uprooted by filling our world with pure, undiscriminating love and acts of kindness,” Rabbi Benny Zippel, executive director of Chabad Lubavitch of Utah, wrote on the group’s website. “We must teach this to all our children, in our schools and our homes.”

To that end, mourners hosted a candle lighting ceremony, “Light Up for Lori,” at 1760 S. 1100 East in Salt Lake City on Friday evening.

“With the passing of Lori Kaye, the world became darker,” Zippel said in a release. “We can only respond to darkness by adding in light.”

Jewish women and girls the world over will “kindle Shabbat candles in loving tribute,” Zippel said, “and in prayer for peace and tolerance amongst all of humanity.”
