In an antisemitic and racist open letter posted on 8chan shortly before the shooting and signed with Earnest 's name , the author blamed Jews for the supposed " meticulously planned genocide of the European race " , known as the " white genocide conspiracy theory " spread by white nationalists , and other ills . He cited shooters Brenton Harrison Tarrant of Grafton , New South Wales , Australia and Robert Bowers of Baldwin , Pennsylvania for their roles in respectively the Christchurch mosque shootings at Al Noor Mosque and Linwood Islamic Centre in Christchurch , New Zealand and the Pittsburgh synagogue shooting at Tree of Life - Or L'Simcha Congregation in Pittsburgh , Pennsylvania , as well as Jesus Christ , Paul the Apostle , Martin Luther , Adolf Hitler , Ludwig van Beethoven , Moon Man and Pink Guy for being the figures who inspired him to commit the Poway shooting as well as a joking mention of PewDiePie and referencing " The Day of the Rope " an event from the 1978 neo-Nazi novel '' The Turner Diaries '' in which Jews , non-whites and liberals are executed including racial slurs targeting African-Americans and Hispanics and urged more violent attacks while avoiding arrest . He condemned President Donald Trump as a pro-Zionist traitor . He also justified his actions by including Bible quotes in his manifesto . The author also claimed responsibility for a March 2019 arson attack on a mosque in Escondido , California , about from Poway . That arson attempt was extinguished with only minor damage to the building and no injuries ; graffiti left in the parking lot made reference to the earlier Christchurch shooting
