Kaye, 60, was shot dead in the synagogue and died in a nearby hospital. In addition to Kaye, at least three more were wounded on Saturday at the Congregation Chabad in Poway north of San Diego.
The 57-year-old Rabbi Yisroel Goldstein had been shot in the hand when Kaye stepped between him and the shooter. The rabbi suffered defensive wounds on both of his index fingers, said a doctor from the Palomar Medical Center.
Roneet Lev, a member of the Congregation and Kaye's 25-year-old friend, was not in the synagogue, but told CNN that she rushed to the hospital when she heard about the shootings. When Goldstein was rolled into the operation, he told her how her friend saved his life, she said.
Kaye attended the service on Saturday to say a Kaddish prayer for her mother, who passed away in November, Lev said.
Kaye's husband is a doctor and hastened to the scene to perform CPR after hearing of the shooting. When he realized that his wife was a victim, he fainted, Lev said.
"She has not died a pointless death," Lev said. "She died to expose the problem we have with anti-Semitism and bring good to this world … If God had put an angel on this planet, it would have been Lori."
Kaye, a native of San Diego, goes behind a husband and a 22-year-old daughter, Lev said.
