BAKERSFIELD, Calif. (KGET) -- The state agency in charge of the certification of California law enforcement officers has made a final decision in the case of a former Kern County Sheriff’s lieutenant charged with sexual and administrative misconduct. David Wesley Hubbard, who as supervisor of the Kern County Sheriff’s Internal Affairs division, regularly presided over investigations into his colleagues’ suspected misconduct, has been decertified by a state agency for his own misconduct. Hubbard had been accused of sexual improprieties with a subordinate in his office while on duty and destroying evidence relevant to the ensuing investigation. Sheriff Donnie Youngblood, in a blistering termination letter, called Hubbard’s behavior ”inexcusable.” The Commission on Peace Officer Standards and Training, following up its advisory board’s recommendation from earlier this year, apparently agreed: POST announced last month that Hubbard’s peace officer credentials have been revoked.  RELATED: Internal Affair Despite that, Hubbard continues to work for the Kern County District Attorney’s office, which hired him after the sheriff's office fired him. A spokeswoman for the county said Hubbard is “still employed as an Investigative Specialist.” DA Cynthia Zimmer did not respond to requests for comment, and efforts to reach both Hubbard and his attorney were unsuccessful. The decertification means, according to a POST spokeswoman, Hubbard can no longer work as a peace officer in the state of California and has no avenues to get his certificate back. His revocation has been reported to the National Decertification Index so it is unlikely he will be able to get a job as a peace officer anywhere else. On a late November weekend in 2021, then-Lieutenant Hubbard and a civilian sheriff’s employee who reported directly to Hubbard, had what both parties describe as consensual sex in his office, while he was on watch commander duty, acting, as POST investigators characterized it, “as the highest ranking law enforcement official in Kern County.”  Hubbard, who months later gave an audio-only interview to a POST investigator, said he was trying to do his job as best he could, given the intimate distraction of the moment. READ: Sheriff Donny Youngblood’s letter to David Hubbard “I had my radio on,” Hubbard told the investigator. “I had my phones on. I was available, as needed. ... I feel like I was, um, able to respond to any situation.” For Hubbard, who is married, sex at the workplace with a lower-ranking employee, who was engaged to another sheriff’s deputy, was serious enough. But the woman also was involved in an apparently unrelated incident involving, again, sex. She reported a second man, a detective sergeant in the same unit as Hubbard, sexually assaulted her. Internal Affairs embarked on a review of that case as well. Hubbard and the woman became concerned about what this detective sergeant might say about other sexual liaisons in the sheriff’s office -- specifically Hubbard’s office affair with the woman.

Suddenly Hubbard was under investigation himself. Internal Affairs would be interviewing him and reinterviewing his subordinate. Hubbard is alleged to then have deleted evidence -- text messages from his work-issued mobile phone, and telephone logs. He is alleged to have interfered with the investigation of the sergeant and improperly shared confidential information with the woman he had sex with, according to the POST findings. Hubbard worked for KCSO from April 2007 to August 2022 and would mark 20 years with the county in 2026.
