On the afternoon of June 2, 1976, Don Bolles, an investigative reporter for The Arizona Republic, was lured to the Hotel Clarendon with the promise of information about a corrupt land deal that involved prominent Arizona politicians. Bolles, who had been hired by his paper as part of an effort to expose corruption and make the city more attractive to businesses and families, told his editor he had serious doubts about the meeting but attended nonetheless. As he left the hotel, an explosive device placed beneath his automobile detonated, inflicting catastrophic injuries.

The blast was powerful enough that Bolles endured an agonizing hospital course during which surgeons amputated both legs and an arm in an effort to save his life. He survived for 11 days after the bombing before dying of his injuries. In the immediate aftermath, Bolles was able to speak with bystanders at the scene, but once he was admitted to the hospital he lost the ability to speak. He nonetheless communicated with investigators through gestures and identified a photograph of the man who had brought him to the hotel: John Adamson.
At the time, the killing of a journalist in such a deliberate, public manner was virtually unprecedented in the United States and drew national scrutiny to Phoenix. The attack was widely described as mob‑style, and the fallout disrupted the city's ambitions to grow while maintaining a small‑town image. The newspaper that had employed Bolles intensified coverage, and reporters from around the country converged on Phoenix to continue probing the kinds of corruption Bolles had been investigating. The event became a focal point for journalists who said the newsroom response sent the message that killing one reporter would only multiply efforts to pursue the story.
Investigations into the bombing stretched across decades. Police detectives assembled voluminous case files, prosecutors pursued charging decisions in multiple rounds, and amateur investigators and journalists have continued to comb through the documents and evidence. Criminal prosecutions extended into the 1990s; prosecutors ultimately charged three men with roles in orchestrating the bombing. Whether someone higher up ordered the attack has not been answered definitively and remains an open question in the case record.
One year after the last man who had been convicted in the case died in prison in 2009, the files were transferred to the state archives. The records — roughly 150 boxes of material — had been under restriction and required special permission for access. In 2010 the documents moved from the office of the Arizona Attorney General to the state archives under conditions that had limited public scrutiny for a half‑century. Recently, the attorney general’s office approved the release of those 150 boxes, allowing journalists and researchers renewed access to the investigative files.

The renewed availability of the case documents has prompted The Arizona Republic to begin a systematic review of the files, part of an effort to examine both the facts of the bombing and the broader context in which Bolles worked. The original investigation and later prosecutions produced a substantial paper trail, but large swaths of the material had not been open to the public until the recent approval. Journalists, historians and legal observers now have the opportunity to trace the investigative steps taken by police, the decisions made by prosecutors over the years, and the evidence presented in trials that followed.
The case of Don Bolles has remained in public memory in part because of its implications for press safety and for the role of investigative reporting in exposing corruption. In the decades since 1976, attacks on journalists have occurred in other parts of the country as well, including a 2018 shooting at a Maryland newsroom that killed five reporters and a 2022 stabbing of a Las Vegas investigative reporter outside his home. The Bolles case continues to be studied by reporters and law enforcement as a historically significant instance of violence against a member of the press.
Prosecutors, detectives and journalists over the years have sought to answer who sought to silence Bolles and why, but the full chain of responsibility has never been conclusively established in public records. The release and examination of the archived case files now underway may add new detail to the record, but as of the reopening of the files, some questions about who ordered the bombing and the broader motives behind it remain unresolved. The review of the material is ongoing as reporters work through the decades of documents now accessible for the first time in many years.
