An Illinois landlord who killed a six-year-old Palestinian American boy and severely injured the boy's mother in a vicious hate-crime attack days after the war in Gaza began was sentenced Friday to 53 years in prison.

Joseph Czuba, 73, was found guilty in February of murder, attempted murder and hate-crime charges in the death of Wadee Alfayoumi and the wounding of his mother, Hanan Shaheen.

Authorities said Czuba targeted them in October 2023 because of their Islamic faith and as a response to the war between Israel and Hamas. The family had been renting rooms in Czuba's home in Plainfield, Ill., about 64 kilometres southwest of Chicago, when the attack happened.

Vermont shooting being investigated as hate crime

The U.S. attorney general says authorities are investigating the shooting of three men of Palestinian descent in Burlington, Vt., as a hate crime. All three were seriously injured but are expected to survive. The accused shooter pleaded not guilty Monday to attempted murder charges.

Central to the prosecution's case was harrowing testimony from the boy's mother, who said Czuba attacked her before moving on to her son, insisting they had to leave because they were Muslim. Prosecutors also played the 911 call and showed police footage. Czuba's wife, Mary, whom he has since divorced, also testified for the prosecution, saying he had become agitated about the Israel-Hamas war, which had erupted days earlier.

Police said Czuba pulled a knife from a holder on a belt and stabbed the boy 26 times, leaving the knife in the child's body. Some of the bloody crime scene photos were so explicit that the judge agreed to turn television screens showing them away from the audience, which included Wadee's relatives.

"He could not escape," Michael Fitzgerald, a Will County assistant state's attorney, told jurors at trial. "If it wasn't enough that this defendant killed that little boy, he left the knife in the little boy's body."

The jury deliberated for 90 minutes before returning a verdict. Czuba is eligible for a minimum prison sentence of 20 to 60 years or life, according to the Will County State's Attorney's Office.

Prosecutors declined to comment ahead of Friday's hearing and have not said what sentence they will seek. Illinois does not have the death penalty.

The attack renewed fears of anti-Muslim discrimination and hit particularly hard in Plainfield and surrounding suburbs, which have a large and established Palestinian community. Wadee's funeral drew large crowds and Plainfield officials have dedicated a park playground in his honour.

Czuba did not speak during the trial. His defence lawyers argued that there were holes in the case. His public defender, George Lenard, has not addressed reporters and declined comment ahead of the sentencing.

Shaheen experienced more than a dozen stab wounds and it took her weeks to recover. She said there were no prior issues in the two years she rented from the Czubas, even while sharing a kitchen and a living room.

Then after the start of the war, Czuba told her that they had to move out because Muslims were not welcome. He later confronted Shaheen and attacked her, holding her down, stabbing her and trying to break her teeth.

"He told me, 'You, as a Muslim, must die,"' said Shaheen, who testified in English and Arabic through a translator.

Police testified that officers found Czuba outside the house, sitting on the ground with blood on his body and hands.

Separately, lawsuits have been filed over the boy's death, including by his father, Odai Alfayoumi, who is divorced from Shaheen and was not living with them.

The U.S. Department of Justice also launched a federal hate crimes investigation.
