The Contra Costa County Sheriff’s Office is facing renewed scrutiny after a 34-year veteran of the department was arrested on four felony charges, including burglary and embezzlement, in a case that has triggered calls for an independent audit of the agency’s property-handling operations.
Detectives took 62-year-old Kevin Lee of Martinez into custody on Thursday, June 12, following an internal investigation into alleged thefts from the Sheriff’s Property Services Unit in Concord. Lee, who joined the department as a deputy sheriff in May 1990 and transitioned to a per-diem role in 2012, had spent his entire career assigned to the unit responsible for cataloging and safeguarding evidence, seized property, and other departmental assets.
The arrest marks one of the most significant internal accountability actions by the Contra Costa Sheriff’s Office in recent years and comes during a broader season of institutional reckoning across the county’s law enforcement agencies. The news follows a period in which multiple Contra Costa institutions have faced heightened public and legal scrutiny over governance, transparency, and operational integrity.
The Charges and Investigation
According to the Sheriff’s Office, the investigation began after department officials uncovered evidence of criminal conduct tied to Lee’s role at the Property Services Unit. Detectives secured both search and arrest warrants before taking Lee into custody, booking him into the Martinez Detention Facility on four felony counts.
| Charge | Classification | Description |
|---|---|---|
| Burglary | Felony | Unlawful entry with intent to commit theft or a felony |
| Receiving Stolen Property | Felony | Possession of property known to be stolen |
| Embezzlement | Felony | Fraudulent appropriation of property by a person entrusted with it |
| Possession of an Assault Weapon | Felony | Unlawful possession of a firearm classified as an assault weapon under California law |
Lee is being held in lieu of $160,000 bail. The inclusion of an embezzlement charge suggests investigators believe Lee misappropriated items or funds entrusted to the Property Services Unit, while the assault weapon possession charge raises significant questions about what detectives found during the execution of search warrants. The Sheriff’s Office has not released details on what specifically was taken or how long the alleged thefts may have been occurring, citing the ongoing nature of the investigation.
Independent Audit Ordered
In an unusual step, the Sheriff’s Office announced it will ask the California Commission on Peace Officer Standards and Training (POST) to conduct an independent audit of the Property Services Unit. POST, the state agency responsible for setting training standards and certifying peace officers, has the authority to review departmental operations and recommend corrective actions.
“All Sheriff’s Office employees are held to the highest standards, and any employee who is involved in criminal conduct will be held accountable,” Contra Costa Sheriff David Livingston said in a statement. “This matter was taken seriously, and a thorough investigation was immediately launched once we learned about it.”
The Property Services Unit plays a critical but often overlooked role in law enforcement, handling evidence seized during investigations, property recovered from crime scenes, and items held for safekeeping or legal proceedings. A breakdown in the integrity of that unit can have ripple effects across active criminal cases and create chain-of-custody issues that defense attorneys could exploit.
What It Means for Walnut Creek
While the alleged thefts occurred in the Concord-based Property Services Unit, the Contra Costa Sheriff’s Office provides law enforcement services to unincorporated areas throughout the county and operates the detention facilities where arrested individuals from all Contra Costa cities, including Walnut Creek, are processed. Walnut Creek contracts with its own police department for municipal law enforcement, but the Sheriff’s Office handles county-wide functions that affect every resident.
For Walnut Creek residents, the case underscores the importance of accountability systems within law enforcement. The willingness of the Sheriff’s Office to conduct an internal investigation and request an outside audit signals institutional self-awareness, but critics may view the audit request as reactive rather than proactive.
A Pattern of Accountability Actions
Lee’s arrest does not occur in isolation. It follows a series of high-profile accountability actions involving Contra Costa institutions, including an FBI raid on the County Assessor’s office earlier this spring and ongoing lawsuits over conditions at county detention facilities.
These events have drawn heightened attention to governance and oversight across Contra Costa County’s institutions. The Sheriff’s arrest case presents a test of whether internal accountability mechanisms work as intended or whether external pressure—from the state, the courts, or the public—is required to force meaningful action.
Who: Kevin Lee, 62, of Martinez — a 34-year veteran of the Contra Costa Sheriff’s Office
Charges: Burglary, receiving stolen property, embezzlement, and possession of an assault weapon (all felonies)
Bail: $160,000
Date of Arrest: Thursday, June 12, 2026
Next Steps: POST audit of the Property Services Unit requested by the Sheriff’s Office
Looking Ahead
The case remains under investigation, and the Sheriff’s Office has indicated that additional details may be released as the POST audit progresses. Lee’s next court appearance has not yet been scheduled. As in all criminal cases, the charges represent accusations, and Lee is presumed innocent unless proven guilty in a court of law.
For Walnut Creek residents tracking governance and public safety in their community, this case is a reminder that institutional integrity depends not just on policies and procedures but on the individuals entrusted to carry them out—and on the willingness of leadership to act when those individuals fall short.
