Rabbi David Niederman said Rodriguez, a 49-year-old worker, died a hero.

“After being shot, he opened the back door for a customer to be rescued,” he told reporters Thursday. “Unfortunately, he died at the footstep of that door.”

His wife choked back tears as she thanked the market that employed her husband for accepting him.

“Especially the Jewish community that learned how to love my husband and was there for him and embraced him,” she said.
