Phil Eil is an investigative journalist who has written for publications such as Vice, Huffington Post, the Boston Globe and the Providence Phoenix. But there was always one story he wanted to write.

In his new book, Prescription for Pain, Phil documents the story of Dr. Paul Volkman, a midwestern physician who was convicted of distribution of a controlled substance resulting in death, plus additional charges.

Phil tells us about the story but also describes the various less-common investigative (OSINT) tools that he used to tell the story.
