Like many prosecutors’ offices throughout the nation, the Multnomah County District Attorney’s Office is organized into specialized units of attorneys. These units focus on particular types of criminal activity and develop an expertise in the investigation and prosecution of defendants charged with those types of criminal offenses. The following is a summary of the four divisions of the office that engage in criminal investigations and prosecutions.

Division One – Chief Deputy District Attorney Amanda Nadell

• Domestic Violence Unit (crimes in the home, crimes against non-family children, victim assistance)
• Multi-disciplinary Team Unit (inter-family physical and sexual abuse of children)
• Juvenile Unit (youth offenders, delinquency, dependency)
• Misdemeanor Unit (case review, charging instruments, arraignments)

Division Two – Chief Deputy District Attorney Mariel Mota

• Strategic Prosecution Unit (Multnomah County District Attorney Access Attorney Program, high-volume crimes)
• Pretrial Unit (extraditions, grand jury, appeals)
• Unit A/B (theft, fraud, identity theft, drugs, gambling, human trafficking)
• Support Enforcement Division (child support enforcement)

Division Three – Chief Deputy District Attorney Todd Jackson

• Unit C (robbery, burglary, gun and other weapons crimes, vehicular homicide)
• Unit D (assault, sex crimes, aggravated assaults)
• Homicide Unit

Investigations Division – Chief District Attorney Investigator Peter Simpson

The Investigations Division is staffed by District Attorney Investigators and is divided into two units – the Investigations Unit and the Body Worn Camera (BWC) Unit. The Division’s primary function is to perform follow-up investigation and trial preparation on cases submitted for prosecution by law enforcement agencies. DA Investigators collaborate with other local, state, and federal law enforcement agencies in Multnomah County and participate in joint operations and task forces. The types of cases requiring follow-up investigation include, but are not limited to, homicide, domestic violence, child abuse, sexual assaults, robbery, burglary, and other crimes.

BWC Unit investigators are specifically tasked with reviewing BWC footage, redacting audio and video files for court, and writing reports on cases submitted for prosecution.

Division staff includes a Chief District Attorney Investigator, Lead District Attorney Investigators, and District Attorney Investigators. Investigators include both sworn and non-sworn law enforcement. Sworn investigators are certified law enforcement officers through Oregon’s Department of Public Safety Standards and Training (DPSST).
