DENVER — The man who killed one woman and injured more than a dozen others in a firebombing on Boulder’s Pearl Street Mall last year pleaded guilty to federal crimes Thursday.

Mohamed Soliman, 46, is already serving a life prison sentence after pleading guilty to more than 100 state crimes in connection with the June 1, 2025, attack. He added 12 federal convictions to that tally Thursday, including nine hate crime counts and three crimes related to using explosives.

Under the terms of the federal plea agreement, both prosecutors and defense attorneys will ask that Soliman be sentenced to life in prison plus 50 years on the federal convictions, prosecutor Melissa Hindman said during Thursday’s hearing in U.S. District Court for the District of Colorado.

Soliman used a makeshift flamethrower and Molotov cocktails to burn people who had gathered on Boulder’s popular pedestrian mall for a weekly demonstration urging the release of Israeli hostages held in Gaza after the Oct. 7, 2023, attacks by Hamas.

Fourteen people were burned, including 82-year-old Karen Diamond, a member of Boulder’s Jewish community who died June 25, 2025, from her injuries.

Witnesses said Soliman shouted “Free Palestine” during his attack. Federal prosecutors pursued hate crime charges because Soliman targeted his victims because they were Israeli or he believed they were Israeli. Soliman’s defense attorneys early on argued the hate crime counts were unsupported because Soliman wanted to target “Zionists,” rather than all Israeli people, and that he considered “Zionists” to be anyone who supported Israel’s existence on Palestinian land.

In his guilty plea Thursday, Soliman admitted he targeted the victims because of their real or perceived religion or national origin. Handcuffed and shackled, Soliman calmly answered Senior Judge John Kane’s questions through a translator during the about hour-long hearing.

Soliman pleaded guilty to the state crimes in May. He previously had offered repeatedly to plead guilty to all 12 federal charges if prosecutors agreed not to pursue the death penalty.

Soliman, who was born in Egypt and lived in Kuwait for 17 years, arrived in the U.S. in August 2022 on a tourist visa that expired in February 2023. He overstayed his visa and sought political asylum in September 2022. He and his family settled in the Colorado Springs area.

Soliman received permission to stay in the United States in February 2023 while his asylum application was pending, according to court records, and received a work permit in March 2023.

His now ex-wife and five children have faced deportation efforts since the attack, though authorities say his family had no involvement in the ambush or knowledge that he was planning it.
