BOULDER, Colorado — Karen Diamond, one of the people burned in the antisemitic firebombing attack on Boulder’s Pearl Street Mall earlier this month, died Wednesday, according to a Monday morning email from the Boulder Jewish Community Center.

“There are simply no words to properly express the pain of this tragic loss,” said the email, which was signed off by JCC Executive Director Jonathan Lev and JCC Board Chair David Paul. “Karen was a cherished member of our community, someone whose warmth and generosity left a lasting impact on all who knew her.”

Diamond, 82, was among the people attacked while participating in a walk by the group Run for Their Lives, which advocates for the release of the remaining 50 Israeli hostages held by Hamas since an October 2023 attack.

As a result of Diamond’s death, the Boulder County District Attorney’s Office announced that it is filing additional charges — including first degree murder — against Mohamed Sabry Soliman, who is accused in the Pearl Street attack.

“In addition to charges related to her death, the extensive investigation has led to more victims being identified,” the DA’s Office said in a Monday morning release. “Criminal charges are now being filed in connection with those additional victims.”

Soliman, 45, is accused of firebombing the group, which injured 14 other people and one dog. He was recently indicted with nine hate-crime counts, two charges that he used a fire or explosive device to carry out a felony, and a single count of carrying an explosive during the commission of a felony.

“In addition to amending Counts 4 and 5 to reflect the death of Karen Diamond, the District Attorney’s Office added 66 counts. These counts are related to 14 additional victims who have now been identified through the ongoing investigation,” the DA’s Office said in the release.

“In total, the amended complaint names a total of 29 victims in the attack. Of the 29 victims, 13 suffered physical injury during the attack. The complaint now contains the 2 counts of first degree murder, 52 counts of attempted first degree murder, 8 counts of first degree assault, 18 counts of attempted first degree assault, 2 counts of third degree assault, 2 counts of using an incendiary device, 16 counts of attempted use of an incendiary device and one count of animal cruelty. “

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

The DA’s office said that Diamond’s family has asked “for privacy as they continue to grieve.”
