Hundreds of people gathered at a community park in Poway Sunday night for a vigil to honor the victims of an attack on a synagogue the day before.
Leaders asked community members to perform acts of kindness in remembrance of Lori Kaye, 60, a longtime member of the synagogue who was killed in Saturday's attack.
Mayor Steve Vaus said he would stand with the community, and Rabbi Yisroel Goldstein, who was shot in the attack, said seeing the crowd come together provided consolation.
"What happened to us, happened to all of us," Goldstein said.
Goldstein told reporters Trump called him to share his condolences on behalf of the American people. He said Trump was comforting and spoke of his love of peace, Judaism and Israel.
Authorities say a 19-year-old man opened fire on the synagogue in Poway, California, during a service on Saturday, killing a woman and wounding three people, including Goldstein.
Rabbi Yisroel Goldstein says the gunman fled after his weapon jammed.
Speaking outside of the Chabad of Poway on Sunday, Goldstein described how he looked up on Saturday and seen a young man wearing sunglasses standing in front of him with a rifle. He said he lifted his hands and was shot, and had lost his index finger in the incident.
And then, Goldstein said, "miraculously, the gun jammed."
"Terrorism like this will not take us down," he said.
Goldstein remembered Kaye as a "pioneering, founding member" of the congregation and said he was "heartbroken" by her death.
A friend of the woman killed in the Southern California synagogue shooting says the victim's physician husband was called to tend to a wounded worshipper and fainted when he realized it was his wife.
Congregation member Roneet Lev related an account from Rabbi Goldstein of how Kaye threw herself in front of him, possibly saving his life. Goldstein is recovering from a gunshot wound to the hand.
Lev says Kaye had gone to the synagogue to say the Kaddish Jewish prayer for the dead for her mother, who had recently died. Lev says now the irony is people will be saying the prayer for her now.
Officials said the two other people wounded in the shooting had been discharged.
Next door to the Chabad of Poway synagogue, Father Alexander Federoff said his Orthodox Christian congregation was in the middle of a prayer service when the gunshots rang out and that his church welcomed Jewish congregants and tried to offer them comfort.
A 19-year-old arrested after the attack is expected to be arraigned this week on charges including murder and attempted murder.
