The Criminal Division is the largest of four divisions in the King County Prosecutor's Office and is organized into several different units and sections. The Criminal Division represents the state and the county in criminal matters in the King County District and Superior courts, the state and federal courts of appeal, and the Washington and U.S. Supreme Courts.

Criminal Division Units

The attorneys in this unit handle appeals in the Court of Appeals, the Washington State Supreme Court and the United States Supreme Court. These attorneys also advise on complex legal issues that arise in the trial courts.

CSU serves as a centralized hub for the collection and sharing of illegal shooting data throughout the County. While firearm homicides are generally known and tracked, nonfatal shootings and shootings not resulting in injury have not historically been tracked in a uniform manner. Not every agency routinely collects this data, and those that do have different definitions, coding mechanisms, and records management systems. As a result, the collection, cleaning, and standardization of this data by the CSU crime analyst is incredibly time and labor intensive.

In the context of illegal shootings, a public health approach addresses the questions of who is being shot; why are they being shot; and how can we prevent future shootings. Those are the questions that CSU has been working to answer and those which we hope to continue to work to address moving forward.

In the 1990s, the number of domestic violence felony cases in King County doubled from approximately 740 in 1994 to over 1500 in 1999. In response to this alarming trend, the King County Prosecutor's Office created the Domestic Violence Unit in early 2000. Organized into six areas at four different locations, the Domestic Violence Unit is responsible for handling all domestic violence felonies in King County, all misdemeanor and gross misdemeanor domestic violence cases from unincorporated areas, as well as providing criminal advocacy services on all domestic violence cases and protection order advocacy to several thousand victims annually.

In addition to a high volume and intense trial practice, the Domestic Violence Unit engages in many innovative practices from utilizing new technologies in investigations, King County Firearms Forfeiture Project, to working with law enforcement and local domestic violence advocacy organizations to promote a coordinated community response.  The Domestic Violence Unit was a founding partner in the domestic violence courts in District Court, and the specialized domestic violence case management system in Superior Court. The mission of the Domestic Violence Unit is to break the cycle of domestic violence by increasing accountability for domestic violence offenders and improving safety for victims of domestic violence and their children.

In 1994, the office, along with Superior Court, created an alternative to traditional prosecution for drug possession crimes. Defendants are offered an opportunity to enter a court-monitored drug treatment program. If they successfully complete the one-year program, the charges are dismissed. If they fail the program, they are returned to the court for a stipulated trial and sentencing.  Read more about Drug Court.

The General Crimes Unit (GCU) handles felony trials and files charges in a variety of cases, such as Assault 3, Felony Harassment, Burglaries, Car Theft, Unlawful Firearm Possession, Escape, and Narcotics Deliveries. GCU is located in the King County Courthouse in Seattle.
Formed in 2017, the High Priority Repeat Offenders Unit (HIPRO) is a unit dedicated to reducing crime rates by focusing on the most prolific burglars and car thieves in our community. The HIPRO unit is the combination of the former Car Theft and Repeat Burglar Initiatives and uses many of the same approaches to reducing crime rates, including “stacking” cases and working to ensure that offenders stay in custody pending trial. The HIPRO unit also works to build relationships with police agencies to encourage thorough burglary and car theft investigations and more prompt filing of cases, and raises community awareness of burglary and car theft prevention.

The Most Dangerous Offender Project (MDOP) is comprised of Senior Deputies who are available seven days a week, 24 hours a day, to respond to every homicide scene in King County. The responding deputy works as part of an investigation team, which includes the detectives, the medical examiner, and forensic scientists. The deputy responding to the homicide scene assumes immediate responsibility for the prosecution -- preparing search warrants, coordinating the efforts of law enforcement and forensic scientists, and offering legal advice to investigators. This deputy's responsibility includes the charging decision and extends to all subsequent legal proceedings from arraignment through trial to sentencing

The Involuntary Treatment Act Unit (ITA)  handles involuntary mental health treatment commitment cases.  Persons with mental illness who present a risk to themselves or others may be detained involuntarily and placed into a local in-patient mental health evaluation and treatment facility (Harborview Medical Center, Fairfax Hospital, Cascade Behavioral Health, Swedish Ballard Hospital, MultiCare Health System, in Auburn, the Geropsychiatric Center of Northwest Hospital or Navos Mental Health Solutions In-patient Services).  The set of laws which allows this is called the Involuntary Treatment Act.  The initial detention is for up to 72 hours.  If the treating facility believes further in-patient treatment is necessary, the facility petitions the court for more time for involuntary treatment.  The patient can contest the need for the detention and treatment, and is entitled to a full hearing governed by the rules of evidence.  By statute, the Prosecuting Attorney's Office is charged with representing the treatment facility seeking longer involuntary treatment.  These proceedings are considered to be civil, rather than criminal, proceedings.

The courtroom for ITA proceedings is located on the second floor of the Ninth and Jefferson Building, across the street from Harborview Medical Center.  ITA Court should not be confused with criminal mental health courts, which are run by either the King County District Court or Seattle Municipal Court and are part of the criminal justice system.

The King County Prosecutor's Office prides itself for creating one of the first specialized units in the country to deal exclusively with cases involving the sexual and physical abuse of children, as well as sexual offenses against adults. Specially trained prosecutors, who are uniquely qualified to deal with the complex and sensitive nature of these cases, staff the Special Assault Unit at both the downtown courthouse and the Maleng Regional Justice Center.

A highly skilled forensic interviewer is available at both sites to assist law enforcement with interviewing children. The interview specialist, having received a Masters in Social Work, employs research-based interview techniques designed to achieve accuracy and objectivity.

Since its creation, the King County Prosecutor's Office Special Assault Unit has worked collaboratively with law enforcement, Child Protective Services and local advocacy groups.

For years, the United States spent staggering amounts of money to imprison people for low-level, non-violent crimes related to mental health issues, addictions, and substance abuse. Jails and prisons reached maximum capacity. Upon release, people re-offended and cycled back into the criminal justice system as recidivism rates remained high. 

Criminal justice experts have turned to therapeutic courts to keep people out of prison while keeping communities safe. In King County, Regional Mental Health Courts, Regional Veterans Court, and CARD (Community Assessment and Referral for Diversion) are committed to helping people find and receive treatment and services.
