Brian Howey is a freelance journalist who won the Polk Award for Justice Reporting after exposing a deceptive police tactic widely used in California. He began the project, which was eventually published by the Los Angeles Times and Reveal, as a graduate student in the UC Berkeley Graduate School of Journalism.

“It’s one thing to hear about this tactic and hear about parents being questioned in this way. It’s another thing entirely to hear the change in a parent’s voice when they realize for the past 20 minutes they’ve been speaking ill of a relative who’s actually been dead the entire time, and to hear that wave of grief and sometimes that feeling of betrayal that cropped up in their voice and how the way that they spoke to the officers afterwards changed.”

This is the fourth in a week-long series of conversations with winners of this year's George Polk Awards in Journalism.
