I spent years chasing the suspicious slaying of Ruben Salazar, a trailblazing journalist who inspired a generation of Latino reporters. (Photo illustration by Martina Ibáñez-Baldor/Los Angeles Times.)...

In the months leading up to the 40th anniversary of the killing of Ruben Salazar, I filed a California Public Records Act request with the Los Angeles County Sheriff's Department seeking documents that might shed light on what happened the day the newsman died. An L.A. Times columnist and Spanish-language KMEX-TV news director, Salazar was shot in the head by a tear-gas missile fired by a sheriff's deputy after rioting exploded in East L.A. during the National Chicano Moratorium Against the Vietnam War on Aug. 29, 1970. The case has been clouded by controversy and speculation for 40 years.

To this day, questions still swirl around the death of L.A. Times columnist and KMEX news director Ruben Salazar, who was killed by a Sheriff's deputy on Aug. 29, 1970. I produced this Ruben Salazar video, pictured above, in 2008 after the U.S. Postal Service unveiled a stamp honoring the reporter's legacy. My Column One article was written in 1995 for  the L.A. Times on the 25th anniversary of the newsman's slaying. I relied on a variety of sources, including friends and colleagues of Salazar, as well as documents from the FBI and LAPD, to reconstruct the final weeks before Salazar was killed by a sheriff's deputy while covering an anti-Vietnam War rally that exploded into violence. I also wrote a follow-up article in 1999, after waiting nearly six years for the FBI's Salazar file.
