Sources: 5. Developments: 2. The Santa Barbara County Sheriff’s Office is facing scrutiny following the arrest of custody sergeant Jeffrey Koeller for alleged overtime fraud. Koeller is accused of embezzlement, grand theft, and forgery after allegedly claiming approximately $93,000 in overtime pay for hours not worked at the Northern Branch Jail between March 2023 and January 2026. This investigation follows the January arrest of another custody sergeant, Segun Ogunleye, who is accused of falsifying timecards to obtain more than $175,000 in overtime compensation. Sheriff Bill Brown stated that investigations into 688 timecards identified Koeller’s entries as suspicious. Koeller has since pleaded not guilty to 64 criminal charges, including misappropriation of public funds. The case has occurred alongside increased scrutiny from the Santa Barbara County Board of Supervisors regarding the Sheriff’s Office’s annual overtime spending, which has reached roughly $20 million over the last two years. Both implicated officers have been placed on administrative leave. ## Timeline ### 2026-08-10: Santa Barbara County sergeant charged with overtime pay fraud Santa Barbara County custody sergeant Jeffrey Koeller pleaded not guilty to 64 charges, including grand theft, for allegedly stealing over $93,000 through fraudulent overtime timecards. 2 sources. https://clstr.news/cluster/santa-barbara-county-sergeant-charged-with-overtime-pay-fraud ### 2026-08-07: Santa Barbara County Sheriff’s Office arrests second custody sergeant over overtime fraud Santa Barbara County Sheriff’s Office arrested custody sergeant Jeffrey Koeller for alleged $93K overtime fraud, the second such case after Segun Ogunleye’s $175K fraud arrest, prompting new oversight measures. 4 sources. https://clstr.news/cluster/santa-barbara-county-sheriffs-office-arrests-second-custody-sergeant-over-overtime-fraud --- Cite as: Santa Barbara County Sheriff overtime fraud investigations.
