Boulder County, Colo. - Based on the tragic death of a victim from injuries suffered in the attack on Pearl Street, the District Attorney’s Office is filing additional charges. In addition to charges related to her death, the extensive investigation has led to more victims being identified. Criminal charges are now being filed in connection with those additional victims.

Today, the District Attorney’s Office amended Counts 4 and 5 from Criminal Attempt to Commit First Degree Murder to Murder in the First Degree. Counts 4 and 5 pertain to the same victim. Count 4 charges First Degree Murder under an extreme indifference theory and Count 5 charges First Degree Murder with intent and after deliberation. Those two murder counts each pertain to the one victim who has passed away.

Karen Diamond, 82 years old, died tragically as a result of the severe injuries that she suffered in the attack.

The District Attorney’s Office has been in close communication with Karen Diamond’s family throughout this difficult time. The family has asked our office to share, “The family asks for privacy as they continue to grieve.”

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.

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.

First degree murder carries the penalty of life without the possibility of parole. Attempted first degree murder carries a prison sentence of 16 - 48 years. First degree assault carries a prison sentence of 10 - 32 years. For at-risk victims, the sentence would be enhanced. Use of an incendiary device carries a prison sentence of 16 - 48 years. Attempted use of an incendiary device carries a prison sentence of 4 - 12 years.

These additional charges, including the counts of First Degree Murder, are being filed after consultation with the U.S. Attorney’s Office, Federal Bureau of Investigation, and the Boulder Police Department. The DA’s Office continues to work closely with federal, state, and local partners in the strong response to this attack. We stand united against acts of antisemitism and hate.

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. Our office will fight for justice for the victims, their loved ones, and the community. Part of what makes Colorado special is that people come together in response to a tragedy; I know that the community will continue to unite in supporting the Diamond family and all the victims of this attack.”

The next court hearing in the state case is the preliminary hearing scheduled for July 15, 2025, at 1:30 p.m. For any questions related to the federal case, please contact the U.S. Attorney’s Office at USACO.PublicAffairs@usdoj.gov
