BROOKE GLADSTONE: This is On the Media. I'm Brooke Gladstone.

BOB GARFIELD: And I'm Bob Garfield. With the recent death of a CBS cameraman and sound man, Iraq has become the deadliest war for journalists; 77 killed compared with 63 in Vietnam and 69 in World War II, according to the Freedom Forum. Sad as those casualties are, we've come to expect them as an occupational hazard. But we're less accustomed to reporters dying on American soil, which may be why the death of Arizona Republic reporter Don Bolles still resonates. He was investigating organized crime when his car exploded in Phoenix 30 years ago this past Friday. Bolles' death was so notable that the Newseum, a journalism museum, set to reopen next year in Washington, will devote an entire gallery to his life. But the following story, which first aired in 2004, isn't about heroism in the line of duty. It's about a unique collaboration of dozens of reporters from around the country, who, drawn together by Bolles' murder, forgot that they were competitors and converged on his hometown to finish his work. It was called the Arizona Project. From Phoenix, Steve Goldstein recounts the tale.

STEVE GOLDSTEIN: When Don Bolles' car was blown up on June 2nd, 1976, the explosion was recorded by an attorney who was dictating in his nearby office.

STEVE GOLDSTEIN: Bolles died in a Phoenix hospital 11 days later, following a series of operations to amputate one arm and both legs. Bolles had investigated organized crime for the Arizona Republic for more than a decade, and made some enemies. The Republic staff tried to fill Bolles' void, turning their shock and anger toward work. Bob Early was a city editor at the Republic, and Don Bolles' boss.

BOB EARLY: When we found out that it was one of our guys, we mobilized the whole effort of reporting it, so there wasn't a whole lot of time to be shocked or to think about it.

STEVE GOLDSTEIN: Meanwhile, in Indianapolis at the inaugural convention of the Investigative Reporters and Editors Organization, an unprecedented decision was made. The IRE would send a team to Arizona to follow up on Bolles' investigations. Newsday's Bob Greene led the team. He says the reporters weren't going to try to solve Bolles' murder. Instead, they wanted to investigate and illuminate the conditions that led to it. They would try to use journalism as a weapon.

BOB GREENE: Here was a society that felt – at least some elements of it – felt it was permissible to kill a reporter to stop his work. Now, the question in our mind was to go out there and examine that society, particularly in light of what he had been working on.

STEVE GOLDSTEIN: Bob Early was glad the reporters were coming to Phoenix.

BOB EARLY: Any kind of show of strength, it seemed to me, would be beneficial for us so that these kind of things wouldn't happen again. The more heat that we could bring onto the criminal element as a result of this, and also, you know, to government and the politicians, would have been very beneficial to us.

STEVE GOLDSTEIN: Over the course of six months, 38 journalists worked on the project. Many of them had never met Bolles. Members teamed up to investigate the influence of organized crime in the state, from prostitution to illegal immigration to land fraud. Six of the team members were involved from start to finish, but most could only commit to a couple of weeks. So Bob Greene developed a system of cross-indexed files that would let newer reporters get up to speed quickly. The group's efforts drew attention in Arizona, and it also sparked high-profile interest from the CBS news magazine "60 Minutes." ["60 MINUTES" SOUNDTRACK]

STEVE GOLDSTEIN: It also got the attention of rival newspapers. The New York Times and the Washington Post said the project was misguided at best. Bob Greene.

BOB GREENE: The New York Times' Abe Rosenthal, who I had great, great respect for, said if this is to be done, it shouldn't be done collectively. The New York Times will do it. The Times didn't do it, so, fortunately, we did. Ben Bradlee in the Washington Post opposed it. First statement he made was that investigative reporters cannot sit in the same room for more than three days without going at each other's throats. It'll never work.

STEVE GOLDSTEIN: But it did work. On March 13th, 1977, newspapers across the country published the first of a 23-part series produced by the Arizona Project team. It chronicled alleged corruption in Arizona business and politics. But none of those stories appeared in Don Bolles' paper. Nina Pulliam, publisher of the Arizona Republic, made the decision. Former city editor Bob Early says the paper should have published the series.

BOB EARLY: What our publisher at the time was concerned about was the fact that we were going to publish things that were, in some tone, accusatory, and so they were concerned about legal action. I didn't have any concerns about that.

BOB GREENE: I was outraged. [LAUGHS]

STEVE GOLDSTEIN: Again, Bob Greene.

BOB GREENE: Here [LAUGHING] was a newspaper that had been cooperating all the way along the line on the Bob Early level, which was the city editor level, and which all of a sudden now is saying they never had any part of the project.

STEVE GOLDSTEIN: Greene wasn't alone in his anger. The general manager of local radio station KOY was stunned by the Republic's decision. So he decided the station should read the series on the air every night at 6:30 to keep Phoenix residents informed. [KOY CLIP FROM 1977]

STEVE GOLDSTEIN: As a reporter for the Indianapolis Star, Myrta Pulliam was part of the Arizona Project. She was affected professionally and personally by the Republic's decision not to publish the series. The publisher was her grandmother.

MYRTA PULLIAM: You know, if somebody kills a reporter, this is the kind of attention that's going to get turned on you. People from all over the country are going to come out here and you're going to be put under a microscope. And no criminal - no person in their right mind wants that to happen to them. I think that that worked. The fact that we were all there, that there was so much attention, really was an insurance policy, and still is to this day.

STEVE GOLDSTEIN: The Arizona Project won a number of journalism awards and was nominated for a special Pulitzer Prize. Three men were convicted in the killing of Don Bolles. One died in 2002. Another was released from prison in 1998, and is free today. The third is still in jail, serving a life sentence in Arizona. For On the Media, I'm Steve Goldstein.
