An off-duty Border Patrol agent was inside when the shooting started. The agent opened fire while the suspect fled outside. At that point, bullets missed the suspect, but hit the man's car door. The shooter then took off down the street where he was eventually taken into custody, after calling 911 to say he was involved in a shooting. When SDPD caught up with him the suspect got out of his car with his hands up and was arrested.

The suspect’s car had a bullet hole in the door and an assault-style rifle sitting on the front seat. Witnesses near the scene told News 8 the suspect was wearing what they described as a tactical vest containing additional ammunition. They went on to say the suspect showed little emotion and some even said he looked somber.

After the arrest, an explosive detection dog was sent to make sure the vehicle and the nearby scene was safe. Then, homicide investigators from the San Diego Sheriff’s Department and agents with the FBI spoke with the suspect.

The shooting took place around 11:30 a.m. as worshipers were celebrating the final day of Passover. About 100 people were inside the temple at the time, San Diego Sheriff Bill Gore said. A Family Assistance Center was set up at Poway High School, located at 15500 Espola Road, so people were able to find out information about love ones from the synagogue. 

San Diego Sheriff's Department closed Eastbound Espola Road at Summerfield Lane and Westbound Espola Road at Avenida Florencia. Espola Road re-opened on Sunday.

California Governor, Gavin Newsom, issued a statement and Representative Juan Vargas also issued a statement on the Poway Synagogue shooting. 

Gore said the San Diego County Sheriff's Department and the San Diego Police Department would conduct a joint investigation of the shooting. FBI San Diego Assistant Special Agent in Charge Omer Meisel said federal agents will work closely with local law enforcement on the investigation.

Gore issued an update Sunday saying that his department along with members of several other local, state and federal agencies worked through the night and interviewed approximately 100 people who were victims and witnesses to the shooting. 

The update stated that authorities believe the gunman acted alone and "without outside support in carrying out the attack."

The investigation is continuing with evidence processing and additional interviews, according to the statement. 

Gore's statement also recognized 51-year-old Oscar Stewart who chased the shooting suspect to a vehicle and an off-duty Border Patrol agent who fired at the suspect striking the car as he drove away. 

"The Sheriff’s Department continues to express its sincerest condolences to those affected by yesterday’s crime. Our hearts go out to those going through this difficult time," the statement read in part. 

A GoFundMe page and Stand with Chabad Poway fundraising page have been set up to help the victims and the Chabad of Poway.  

A candlelight vigil was announced for Sunday night at 7 p.m. at Valle Verde Park in Poway. Rabbi Yisroel Goldstein is expected to be in attendance.

Chabad of Poway released the following statement on the support received from the community. 

"The outpouring of love and support from our entire community, across the country and around the world in this very difficult time has brought us much comfort. A piece of us has been torn away with the loss of Lori. She came to synagogue to say Yizkor for her mother and instead we all said Yizkor for her. Please have Rabbi Yisroel Goldstein — Harav Yisroel ben Chana Priva — הרב ישראל בן חנה פריווא — the founding rabbi of Chabad of Poway; as well as Noyah bat Eden — נואה בת עדן — and Almog Yosef ben Ruti — אלמוג יוסף בו רותי — in your thoughts and prayers for their recovery.
