One dead, three injured at Southern California Chabad synagogue on last day of Passover

SAN DIEGO — One person died after a shooting at a Chabad synagogue in a San Diego suburb on Saturday, the last day of Passover, the mayor of Poway, California, said.

One suspect is in custody, and "we’re confident that there are no shooters that are outstanding,” San Diego Sheriff’s Sgt. Aaron Meleen told reporters.

Meleen said deputies responded to Chabad of Poway at approximately 11:23 a.m. “regarding an active shooter situation" and that deputies “found several victims with varying injuries."

Multiple law enforcement sources told NBC News that four people were shot. Poway Mayor Steve Vaus said on MSNBC that one person died.

A motive in the shooting was unclear.

The FBI was also on the scene, according to Davene Butler, spokeswoman for the bureau's San Diego office. "We are working closely with our local partners at this time," she said.

Chabad of Poway had advertised an 11:00 a.m. "Passover Holiday Celebration" online.

Saturday is the traditional weekly day of Jewish Sabbath. This Saturday is also the final day of Passover, a week-long holiday marking the deliverance of the Jewish people from slavery in ancient Egypt.

The Chabad synagogue serves as a community center for ultra-Orthodox Jews. Chabad is known for reaching out to non-Orthodox Jews to encourage them to partake in Jewish life and join some celebrations.

Meleen said he did not know if the incident was religiously motivated. He said the person detained "they were detained down the road."
