Mohamed Sabry Soliman will spend the rest of his life behind bars for firebombing a pro-Israel demonstration in Boulder, Colorado, that killed an 82-year-old woman and injured more than a dozen people. A judge sentenced him Thursday after he pleaded guilty to all 101 state charges, including first-degree murder.
Chief District Judge Nancy Salomone handed down the sentence, life without the possibility of parole, one day after Soliman changed his plea from not guilty to guilty. Colorado has abolished the death penalty, so life without parole was the maximum sentence available under state law.
But the case is far from closed. Soliman still faces separate federal hate-crime charges, and prosecutors are weighing whether to seek the death penalty in that proceeding. The federal case could impose a punishment the state no longer allows.
On June 1, 2025, demonstrators gathered in Boulder to show support for Israeli hostages held in Gaza. Soliman threw Molotov cocktails into the crowd while yelling "Free Palestine," AP News reported. The firebombs killed 82-year-old Karen Diamond and injured at least a dozen others.
Investigators allege Soliman planned the attack for a year and was motivated by a desire to kill "all Zionist people," Newsmax reported. That detail, drawn from what Soliman allegedly told prosecutors, undercuts his courtroom claim that the attack was not antisemitic.
Judge Salomone rejected that distinction outright. She told Soliman directly that the evidence showed he chose his victims because of who they were.
"You chose a time and a place and a set of circumstances and weapons that were designed to inflict the most pain that you could."
She added: "You chose to victimize these people because they were members of the Jewish community."
Soliman spoke publicly before sentencing. He admitted his opposition to Israel but framed it as a political stance rather than religious hatred.
"Yes, I am against Israel, and I can't deny that. And that's my right."
He also expressed regret, of a kind. Just the News reported that, citing the New York Times, Soliman said he regretted carrying out the attack and believed he deserved the death penalty. Through an interpreter, he told the court he would not have acted had he known the consequences.
"If I went back, I would not have done this, as this is not according to the teaching of Islam."
Of Karen Diamond, Soliman said: "There are no words that can express my sadness for her passing."
The judge was unmoved. So was the Diamond family. In a statement read during the proceedings, Diamond's sons made their position plain, as Breitbart reported.
"We ask only that the attacker never sees his family again since he is responsible for our mother never seeing her family again."
Soliman was in the United States illegally at the time of the attack, living on an expired tourist visa, the New York Post reported. That fact alone raises hard questions about how a man who had overstayed his lawful entry was able to remain in the country long enough to plan and carry out a lethal terror attack.
The case fits a grim pattern. Across the country, violent crimes committed by individuals who should not have been here in the first place have become a recurring flashpoint, from a Salvadoran migrant charged with murdering two New York women to other cases that expose the gap between immigration law on the books and immigration enforcement on the ground.
Soliman's expired visa did not trigger removal. His year of alleged planning did not trigger detection. And on June 1, 2025, Karen Diamond paid the price.
Soliman pleaded guilty to all 101 state charges. He acknowledged in court that he was waiving his right to a trial and to any appeals. That decision eliminated the possibility of years of state-level litigation and guaranteed an immediate life sentence.
The speed of the resolution stands in contrast to the drawn-out proceedings that often define high-profile criminal cases. In some courtrooms, judges have shown more concern for the conditions facing accused violent offenders than for the victims left behind. Here, Judge Salomone left no ambiguity about where accountability lay.
Still, the federal case looms. Federal prosecutors have not yet announced whether they will seek the death penalty. Under federal law, an attack motivated by political views alone is not classified as a hate crime. But the judge's finding, that Soliman targeted victims because they were Jewish, and his alleged statement about wanting to kill "all Zionist people" could support a hate-crime prosecution at the federal level.
Karen Diamond was 82 years old. She went to a vigil. She did not come home. Her sons will never see her again because a man on an expired visa decided that her support for Israel made her a target.
The question of what justice looks like in cases this severe is not abstract. Across the country, families grapple with whether the legal system treats violent crime with the gravity it deserves, whether it is a random attack on a store employee or a premeditated firebombing at a peaceful demonstration.
Colorado's abolition of the death penalty meant that life without parole was the ceiling for state charges. Soliman himself said he deserved the death penalty. The federal case may yet test whether the system agrees.
Soliman's attempt to draw a line between anti-Zionism and antisemitism collapsed in the courtroom. He targeted a Jewish gathering. He threw firebombs. He killed an elderly woman. Judge Salomone called it what it was. The distinction Soliman tried to maintain is one that prosecutors in politically charged cases increasingly refuse to let defendants hide behind.
The 101 guilty pleas, the waived appeals, the life sentence, none of it brings Karen Diamond back. But at minimum, it ensures that the man who killed her will never walk free again under Colorado law.
When a man plans an attack for a year, firebombs a peaceful gathering, and kills a grandmother, and the system still has to debate whether it was a hate crime, the problem isn't the label. It's the hesitation.
