An 82-year-old Colorado woman who was injured in the June 1 firebombing of a peaceful pro-Israel march has died.

The Boulder County District Attorney’s Office said Karen Diamond, one of 13 people who were wounded, succumbed to “the severe injuries that she suffered in the attack.” She died on June 25, and her family held a private burial. She is survived by her husband, two sons and daughters-in-law, and five grandchildren.

“This horrific attack has now claimed the life of an innocent person who was beloved by her family and friends,” Boulder County District Attorney Michael Dougherty said in a statement. “Our hearts are with the Diamond family during this incredibly difficult time.”

Congregation Bonai Shalom rabbi Marc Soloway wrote, “This event and the tragic loss of someone who has given so much of herself over the years to the Bonai community and beyond, has impacted us all and we are sad and horrified.  We will need to support each other as we process this loss.”

Governor Jared Polis (D., Colorad0) said he was “devastated” to hear of her passing. “This loss is deeply felt by the Boulder community and our entire state, particularly within our strong Jewish community. My heartfelt condolences go out to her friends and family.”

The attack was carried out by Mohamed Sabry Soliman, an Egyptian national who was in the U.S. illegally. He yelled “Free Palestine” as he threw Molotov cocktails at the marchers, who were calling for the release of the Israeli hostages held by Hamas since the October 7, 2023 terrorist attacks.

According to the arrest affidavit, Soliman had planned the attack for more than a year but waited for his daughter to graduate from high school.

Investigators say Soliman told them he intended to kill the participants in the demonstration and attempted to purchase a gun, but was unable to because of his immigration status.

Soliman’s defense attorney has argued that the attack was not a hate crime because it was motivated by Soliman’s opposition to Zionism. Under federal law, attacks motivated by political views are not categorized as hate crimes. Soliman is represented by public defenders who do not comment on cases to the media. He is due to appear in state court on July 15.

Soliman was indicted last week and has been charged with two counts of first-degree murder, 52 counts of attempted first-degree murder, two counts of using an incendiary device, 16 counts of attempted use of an incendiary device, eight counts of first-degree assault, 18 counts of attempted first-degree assault, two counts of third-degree assault, and one count of animal cruelty.
