FILE - In this Sunday, April 28, 2019 file photo, a San Diego county sheriff's deputy stands in front of the Poway Chabad Synagogue in Poway, Calif. The gunman who attacked the synagogue last week fired his semi-automatic rifle at Passover worshippers after walking through the front entrance that synagogue leaders identified last year as needing improved security.

"Obviously we did not have a chance to start using the funds yet," Rabbi Scimcha Backman told The Associated Press. (AP Photo/Denis Poroy, File)
