The filings say Soliman has reached an agreement with federal prosecutors but do not describe its terms. He faces 12 federal charges, including hate-crime counts, which he had previously contested when pleading not guilty.

The federal case stems from the June 2025 attack at the Pearl Street Mall, where Soliman threw homemade incendiary devices at people taking part in a weekly walk supporting Israeli hostages. The gathering was organized by Run for Their Lives, a group that had been meeting for nearly two years to draw attention to hostages taken in Hamas’ Oct. 7, 2023, attack on Israel.

The attack killed Karen Diamond, 82, who died in hospital three weeks later from burn injuries. Twenty-nine other people and a dog were injured, according to a caption accompanying a photograph of a memorial. Soliman, 46, is serving a life sentence on state charges related to the attack.

The agreement also calls for Soliman’s lawyers to drop a motion seeking to prevent the deportation of his former wife, Hayam El Gamal, and their five children while the federal case proceeds. The family’s attorney said they understand that no legal process can undo the harm caused, but hope the prosecution’s conclusion can offer victims “a measure of finality and closure.”

Soliman had sought to keep his family in the United States to assist with his defense if prosecutors pursued the death penalty. El Gamal and the children, who were ages 5 to 18 at the time of the attack, spent nearly 10 months in immigration detention in Texas before a federal judge ordered their release. The family had immigrated from Egypt and had a pending asylum case; they had been living, working and attending school in Colorado Springs since 2022.
