An Irvine man who composed “kill lists” with names of prominent Jewish community members and a list of steps for “killing my first Jew,” pleaded guilty to civil rights charges Friday in connection with threats against three Orange County houses of worship, along with an unrelated gun charge, officials said.

Nicholas Wesley Rose, 28 had conducted extensive internet searches on a synagogue and church in Irvine and another church in Lake Forest, and visited them between December 2017 and April 2018, said Kimberly Edds, spokeswoman with the Orange County District Attorney’s Office.

Rose was sentenced Friday to 825 days in county jail, one year in a residential mental health treatment program, and five years formal probation with GPS monitoring, Edds said.

In April 2018, Orange police officers searched Rose’s apartment and found ammunition, anti-Semitic literature and “kill lists” of Jewish community members, which included well-known names in the entertainment industry. They also found notes referring to a synagogue in Irvine, a Greek Orthodox church in Irvine and a Russian Orthodox Church in Lake Forest, in the latter two cases over sympathies the churches expressed to Jewish people.

In addition, investigators found a breadth of internet searches of white supremacy ideology, anti-Semitic literature, and the effective range of a silenced .22 long range rifle. In Rose’s car were hundreds of rounds of .22 caliber ammunition, a sleeping bag and shovel.

Rose’s parents had called authorities after they heard their son spew anti-Semitic language, saying that he wanted to “get a gun and kill some Jews.”

Brian Gurwitz, Rose’s lawyer, said while his client’s anti-Semitic writings were very troubling, Rose also wrote about having respect for Jewish people.

“They were the extremely disorganized thoughts of a young man suffering from mental illness,” Gurwitz said.

On Friday, Rose pleaded guilty to three misdemeanor counts of violation of civil rights pertaining to the threats against the houses of worship, and one felony count of carrying a loaded firearm that was not registered to him, the DA’s office said.

Rose had originally faced three felony counts of attempted criminal threats, which were reduced to misdemeanors in a deal with the DA’s office, Gurwitz said. The felony gun charge, not related to the threats, involved a separate incident in October 2017.

Rose did not possess a gun in 2018 when making the threats, and the DA’s office agreed to throw out a felony attempted murder charge in the case, which would have carried the possibility of a life prison sentence.

As a part of his sentence, Rose is also required to stay 500 yards away from his victims and cooperate with the Orange County Probation Department regarding additional mental health treatment.

“There is no place for hate,” said Orange County District Attorney Todd Spitzer in a statement. “He is a danger to society and every resident of Orange County should be aware of the threat he poses.”
