(Video: Rich Marosi/Robert J. Lopez) I spent 22 years at the Los Angeles Times, where I worked on investigative and multimedia projects across the United States and in Mexico and Central America. I had a wonderful career and was part of a team of reporters that won the 2011 Pulitzer Prize for Public Service for exposing government corruption in Bell, a small city southeast of Los Angeles. But I was offered a great job and realized that it was time to take on a new and exciting challenge.

I was part of a team of Los Angeles Times reporters and editors that was awarded the 2011 Pulitzer Prize gold medal for public service for a series of stories exposing alleged government corruption in the City of Bell.

In 1994, I filed my first California Public Records Act Request to review the Sheriff's Department files on Ruben Salazar. The department denied the request, saying the records were confidential law enforcement files. I made another CPRA request in 1995. It, too, was denied. Then in early 2010, as the 40th anniversary of Salazar's slaying approached, I filed another request with Sheriff Lee Baca. He refused to release the files.

Finally, in late February 2011, Baca agreed to allow a limited viewing of the once-secret records by journalists and academics.
