Federal investigators say a former CIA worker who pleaded guilty to sexually abusing women may have more victims, and are asking them to come forward before his sentencing next year.

Forty-five-year-old Brian Jeffrey Raymond pleaded guilty in July to two counts of sexual abuse in which women were incapable of giving consent, and one count of transporting obscene material, after FBI and State Department recovered images from his electronic devices showing two dozen women, nude and unconscious taken between 2006 and 2020.

Raymond admitted to recording or photographed the unconscious women, and to touching their breasts, buttocks and, or genitalia without consent. Many of the victims met Raymond through various dating apps, FBI officials said Tuesday in a statement.

“Almost all of the women in the photos and videos experienced memory loss during their time with Raymond and had no knowledge of the photographs, videos, or any physical contact.,” the FBI said in a news release. “Some women depicted in the recovered photographs and videos remain unidentified.”

Raymond, who speaks Spanish and Mandarin Chinese, is described as a frequent traveler who has lived in a number of countries, including Mexico and Peru, and has also resided in the D.C. and San Diego areas.

Investigators with the FBI and the State Department’s Diplomatic Security Service began looking into Raymond after a nude woman was seen calling for help from the balcony of his residence in Mexico City, where he lived while working at the U.S. Embassy from Aug. 2018 to May 2020.

The FBI is asking anyone who believes they have been a victim of Raymond or has information about him to contact the agency by filling out a secure questionnaire, emailing ReportingBJR@fbi.gov or calling 1-800-CALL-FBI.

Raymond is scheduled to be sentenced in the U.S. District Court in Washington, D.C., on Feb. 7, 2022, following a pre-sentencing evidentiary hearing beginning Jan. 31, 2022.
