NEWS RELEASE SUMMARY – August 12, 2022

SAN DIEGO – Former San Diego Police Officer Peter Griffin and three others are charged in an indictment partially unsealed today with crimes related to owning and operating five illicit massage businesses in California and Arizona that sold commercial sex under the guise of offering therapeutic massage services.

Griffin was arrested as he left his San Diego home early yesterday morning and made his first appearance in federal court today. Likewise, defendants Kyung Sook Hernandez and Yu Hong Tan were also taken into custody Thursday and appeared in federal court today. A fourth defendant remains at large.

According to the indictment, Griffin owned and operated the businesses with Kyung Sook Hernandez, Yu Hong Tan, and the fourth defendant at various times between 2013 and August 2022. Their alleged criminal scheme included using cell phones, the internet, and banking channels to register their businesses; advertise commercial sexual services online; employ multiple women to perform commercial sexual services in the businesses; manage the illicit businesses’ finances; and benefit financially from their illegal enterprise.

Griffin, who is also a former attorney, previously worked as a detective with the Vice Operations Unit of the San Diego Police Department, a unit tasked with dismantling the businesses he now stands charged with operating and promoting.

Assistant U.S. Attorney Jill Streja of the Southern District of California, Trial Attorney Caylee Campbell of the Money Laundering and Asset Recovery Section of the Criminal Division of the Department of Justice, and Trial Attorney Leah Branch of the Civil Rights Division’s Human Trafficking Prosecution Unit are prosecuting the case.

The investigation was led by Homeland Security Investigations, Internal Revenue Service Criminal Investigation, and the San Diego Human Trafficking Task Force, a regional, multi-agency effort led by the California Department of Justice dedicated to supporting survivors and holding traffickers accountable. The task force is comprised of numerous federal, state, and local agencies as well as the Southwest Border High Intensity Drug Trafficking Area program.
