A Kansas judge has sentenced a man to death after he killed three people last year in an alleged hate crime.

Relatives of the shooting victims were successful in convincing the judge to give Cross the ultimate punishment after he tried and found guilty in August of targeting Jews in the April 2014 attack, according to a CNN report.

Judge Thomas Kelly Ryan affirmed the jury’s verdict and sentenced Cross to death by lethal injection.

Cross had a history of anti-Semitic and white supremacist views that culminated in an attack on a Jewish center last year, which left three people dead, including a 14-year-old. The mother of the boy played audio of her son singing the national anthem over her cell phone in the courtroom. Reat Griffin Underwood had been on his way to a high school singing competition when the gunman opened fire.

Cross represented himself during the trial. The prosecutor called him the “most disruptive, evil human being I’ve encountered in my career,” according to the report.

Cross killed 69-year-old William Lewis Corporon and Underwood at a Jewish community center in a suburb of Kansas City before then going to the nearby Village Shalom Retirement Community and gunning down 53-year-old Terri LaManno.

Cross was disruptive during the proceedings, shouting “Heil Hitler” multiple times after the judge read the sentence. Ultimately, he failed in his goal: none of the three victims he shot were Jewish.
