Paul Holes is a New York Times bestselling author, podcaster, television host and retired Cold Case Investigator with the Sheriff and District Attorney’s Offices in Contra Costa County, located in the Bay Area of California. During his 27 year tenure as an investigator, Holes developed and applied investigative, behavioral, and forensic expertise in notable cases such as Zodiac, the Golden State Killer, and Jaycee Dugard. In May 2022, Holes released his debut book, Unmasked: My Life Solving America's Cold Cases (Celadon Books) -- which became an instant New York Times bestseller. In this memoir, he gives readers a deeply personal look into his life and career for the first time.

Paul is frequently sought out by investigators to consult on the most complex and high-profile cases. As an FBI Task Force Officer employed with the DA’s office, Paul teamed with FBI and Sacramento DA personnel to apply innovative technology that identified Joseph DeAngelo as the Golden State Killer, the most prolific serial predator in U.S. history.

Since the arrest of DeAngelo, Paul has become a go-to true crime expert in the media. In 2019, he teamed up with Oxygen to host The DNA of Murder with Paul Holes and in 2022 hosted an original series with HLN called, Real Life Nightmare with Paul Holes.

When he isn’t working, Paul enjoys mountain biking and off-road Jeeping.
