Montgomery County Police Chief Marc Yamada is out of a job after nearly four decades on the force, and county officials now say it wasn't a quiet retirement — it was a resignation amid an ongoing Inspector General investigation. County Executive Marc Elrich confirmed on Thursday that his office requested Yamada's resignation while the Office of the Inspector General's investigation remained pending public release.

The announcement initially arrived without explanation. As WBAL reported, early statements from both the county executive's office and the police department gave no public reason for Yamada's sudden departure, leaving residents to wonder what prompted the abrupt exit of a chief who had served Montgomery County for nearly 38 years. That silence didn't last: Elrich acknowledged the ongoing OIG investigation, according to The Washington Post.

What Investigators Found

At the center of the OIG investigation is an allegation in a whistleblower complaint that Yamada brought a relative — who is also an MCPD officer — to a Las Vegas conference on the county's dime under the guise of a “protection detail.” The station's report notes the inquiry began after council members received whistleblower complaints raising concerns about the chief's travel and leave practices.

The inspector general's synopsis described at least five days and 40 hours of absence without required leave. That unauthorized time reportedly included attendance at a golf tournament where he consumed alcohol, per the Montgomery County Government synopsis.

A Class A Violation Under County Law

An allegation of dishonesty could carry legal weight. Providing false or misleading information in connection with an inspector general investigation would violate county code, but whether that occurred remained under investigation.

This was not the first flag raised about Yamada's conduct this month. An earlier OIG report, released in September, found that Yamada helped arrange the unauthorized use of a police department fleet vehicle for a former county attorney's personal use — an arrangement the Maryland Daily Record notes the county's chief administrative officer had not approved.

A Trailblazing 38-Year Career

Yamada's exit closes out a career that began when he joined MCPD in 1988. He worked in patrol and as a narcotics detective, served as a lieutenant in Wheaton, supervised major crimes, and later became director of community engagement, according to background reported by WUSA9. Elrich nominated him in 2024.

Yamada became Montgomery County's police chief after unanimous confirmation by the Montgomery County Council in 2024. Hoodline previously noted Yamada's community appearances during National Night Out last year.

Acting Chief Steps In Amid Staffing Strain

Darren Francke, who previously served as an assistant chief, is now serving as acting chief until a permanent replacement is named.

He inherits a department under real strain. Montgomery County Police serves Maryland's most populous county, with nearly 1.1 million residents and about 1,100 sworn officers. The staffing challenge now falls to Francke as he keeps the department running through the leadership transition. The police department has said it remains committed to transparency, accountability, and maintaining the public's trust as day-to-day operations continue.
