The family of accused San Diego synagogue shooter John Earnest said Monday the 19-year-old is the latest example of a “history of evil” against Jews — while blaming others for the teen’s radicalization.

“He has killed and injured the faithful who were gathered in a sacred place on a sacred day,” the family said in a statement released through their attorney on Monday. “To our great shame, he is now part of the history of evil that has been perpetrated on Jewish people for centuries.”

The statement came two days after Earnest opened fire inside the Chabad of Poway synagogue, killing one congregant and injuring three others, including an 8-year-old girl and a rabbi.

Earnest’s family said he was raised in a loving home and called his descent into darkness a “terrifying mystery.”

“Our son’s actions were informed by people we do not know, and ideas we do not hold,” the family said, adding that they are cooperating with police as they investigate the “evil and despicable act.”

Threats to attack the synagogue were posted to far-right message board 8 Chan by a writer using Earnest’s name just before the attack.

Earnest grew up in a middle-class home near Poway and was described as a talented honors student and accomplished piano player at Mt. Carmel High School.

In the hours before the attack, Earnest allegedly published an anti-Semitic tirade in which he idolized Christchurch, New Zealand, mosque attacker Brenton Tarrant and Robert Bowers, the man accused of murdering 11 Jews at the Tree of Life synagogue in Pittsburgh last year.

“[Brenton] Tarrant was a catalyst for me personally. He showed me that it could be done. And that it needed to be done,” the document reads, referencing the man who allegedly shot and killed 50 Muslims on March 15.
