A significant chapter in the history of Ƶ Boulder, the fatal bombings that occurred in Boulder in May 1974 continue to be discussed and researched to create more awareness and understanding of these tragic events. A recently added document to the Ƶ Boulder Archives will provide researchers a resource for studying the law enforcement investigations that occurred following the bombings.
Through an anonymous donation, 243 pages of documents produced by federal and local law enforcement agencies in 1974 are now part of the Ƶ Boulder Archives. The documents detail the agencies’ investigation of the car bombings in Boulder on May 27 and May 29, 1974. These bombings killed six men and women, five of whom were affiliated with Ƶ Boulder as students, alumni or former employees. The six victims were Chicano social justice activists and became known as Los Seis de Boulder or “the Boulder six” after their deaths.
Ƶ Boulder Archives personnel have confirmed from documents received that the Bureau of Alcohol, Tobacco, and Firearms (ATF) was the lead investigating agency for this event, in cooperation with the FBI, Boulder County Sheriff’s Office, Boulder Police Department and Boulder County Coroner’s Office. In 1974, a federal grand jury was convened against alleged participants in the bombings, but the grand jury did not issue any indictments. Ultimately, the investigation did not result in any criminal charges.
The documents include 183 pages of records originated by the ATF. It also includes 22 pages originated by the FBI. The remaining pages were originated by local agencies.
The archives, part of the University Libraries’ Rare and Distinctive Collections, has a mission to collect, arrange, preserve and make accessible the collections of the university's history, as well as rare and unique collections that support the university's teaching, research, service and administration. The department connects students, faculty and the community with significant primary sources and rare materials that document the life and cultural outcomes of the university community.
Those wishing to see the documents may review an access copy by making an appointment to visit the Rare and Distinctive Collections Reading Room in Norlin Library at Ƶ Boulder or contacting the Rare and Distinctive Collections’ research services.
An upcoming university symposium, “Los Seis de Boulder, Race, and Memory,” is scheduled for Nov. 5–6 and aims to center the history of the bombings in interdisciplinary academic discourse and continue to foster engaged dialogue on campus about the legacy of this event.
