The association has raised more than $800,000 in pledges through a telethon. On Sunday, a steady stream of people stopped by the community center to deliver checks and drop off blankets, clothing and toys.

"Everyone has helped, and I'm so thankful," said Behzadpour's wife, Lila. "It makes you feel less alone during this very sad time."
