The DA’s Office

The Yolo County District Attorney’s Office Investigations Bureau led by Chief Investigator John Ehrk is comprised of sworn peace officers and support staff focused on the organizational mission to Seek Justice. Do Justice. Most of the Bureau staff come to the District Attorney’s Office with a variety of investigative experience and expertise.

The primary role of the Investigations Bureau is to provide support to trial attorneys and local law enforcement in gathering facts and building trial-ready cases. Often there is a considerable amount of supplemental investigative work that the Bureau staff conducts after a case is handed off to the District Attorney’s Office from a local law enforcement agency.

The Investigations Bureau also has a role in building criminal investigations from the ground up. Members of the Bureau also participate in the county Special Investigations Unit. Additionally, select investigative staff also provide investigative services through the DA’s Fraud Unit and the Consumer Fraud and Environmental Protection Division (CFEPD). Members of the Fraud UniHigh Tech Investigationst focus on issues related to Real Estate fraud, Workers’ Compensation Insurance fraud, and Auto Insurance fraud. CPEPD staff conduct investigations of business practices and crimes against consumers as well as crimes that harm the environment.

The District Attorney’s Office also provides the specialized resources for child sexual assault forensic interviews at the Multi-Disciplinary Interview Center (MDIC), and conducts the bulk of the digital forensic analysis for the county in the High Tech Crimes Unit.

Conviction & Sentence Review Unit

This Unit reviews and investigates claims of innocence raised after a criminal conviction involving homicides, sex offenses and violent crimes. The unit may examine claims of innocence in other types of cases if a significant prison commitment or collateral consequence indicates that an examination of the case is warranted. In addition, the Unit shall be responsible for ensuring that any claim of Prosecutorial Misconduct made during the pendency of any criminal matter is thoroughly investigated and litigated prior to the completion of that pending criminal matter.

In 2019, the Unit moved to dismiss a great bodily injury enhancement in an assault case where later-produced evidence called into question whether that particular defendant (part of a group who were convicted of robbing and assaulting two victims in a parking lot) could have generated the force necessary to cause the specific injuries inflicted.

The Unit shall consist of the Assistant Chief Deputy and an assigned Deputy District Attorney. No assigned personnel shall conduct the examination and/or investigation into any matter that he/she was assigned as the primary prosecutor during the pendency of the initial prosecution. Any other Deputy District Attorney assigned to assist in the examination and/or investigation of a conviction review case shall not have had responsibility for the initial prosecution of the case.

 

Successful Case Resolutions

Protocol

All Post-Conviction claims of actual innocence, no matter in what form the claim is raised, shall be forwarded to the assigned Assistant Chief Deputy District Attorney for review. The Assistant Chief Deputy shall insure that the claim is properly documented in our Case Management System, LawSuite, and that the claim and the file are uploaded and assigned an entry number.

The Assistant Chief Deputy District Attorney shall review each claim to determine whether any further action or investigation is warranted. If after conducting the initial review a determination is made that the claim does not warrant further investigation, the Assistant Chief Deputy District Attorney shall notify the defendant (or requesting party) and any known counsel that no further action will be taken on the claim. Claims with strong indicia of actual innocence will be investigated by Unit personnel.

At the conclusion of the investigation, the Assistant Chief Deputy District Attorney shall determine whether all avenues of inquiry have been exhausted and whether based on the investigation there is a plausible claim of innocence. The existence of a reasonable doubt does not necessarily result in a conclusion that the defendant is actually innocent, the conclusion must be that there is clear and convincing evidence that there exists a plausible claim of actual innocence in the case.

Case Review

The Assistant Chief Deputy District Attorney shall prioritize the examination and review of cases as follows:

  1. Homicides;
  2. Sexual Assault Cases;
  3. Violent and Serious Felony cases involving substantial state prison commitments; and
  4. Other felony cases involving a substantial prison commitment or other significant collateral consequence.

While cases where a defendant entered a plea of guilty or no contest will not be excluded from review, as the possibility exists that an innocent defendant may have plead to a crime he/she did not commit to avoid a potential significant sentence.  However, these cases require greater scrutiny and the Claim of Innocence initially submitted must be compelling. To submit a claim of innocence, please fill out the CSRU-REQUEST-FORM and deliver it to our office.

There shall be greater scrutiny when there are claims of actual innocence that cite newly discovered evidence that bears on innocence or that raise claims that have been found to be “red flag” issues such as misidentification, witness recantation, lying by an informant/cooperator, meaningful claims of alibi, or substantial Brady violations that would appear to involve actual innocence.

Caveats

As a general policy, the Unit will not investigate, in the absence of other compelling justification, claims where a defendant knew or should have known the basis of his/her current claim at the time of the conviction, or where the defendant now disavows his/her trial testimony and offers a different theory of innocence. In addition, except where there is a compelling showing that a guilty or no contest plea was entered to avoid a more significant sanction, the defendant must have continually maintained his/her innocence from the inception of the case.

Pilot Project with For the People

We have now partnered with the non-profit “For the People” (FPL) on a project to revisit certain lengthy prison sentences that, although not erroneous, are no longer in the interest of justice. Part of conviction review includes the examination of certain lengthy prison terms to verify that they are still necessary. Some convictions, though valid, have prison terms that, after a thorough review, may prove to no longer be necessary to protect public safety because the ends of accountability, protection and rehabilitation are met. FPL drafted and advocated for the passage of AB 2942 (Ting) which allows prosecutors to revisit sentences in the interest of justice. We have now partnered with FPL to create criteria and to review these sentences, with cooperation from the Department of Corrections to access necessary rehabilitation data. The current criteria of the program is that (a) the inmate has served at least seven (7) years of a prison term that is at least fifteen (15) years, (b) the inmate is not serving a prison term for a crime listed as “serious” under Penal Code Section 1192.7(c), or a crime listed under Section 667.5(c) a.k.a. “violent” crimes, (c) the inmate is not a 290 registrant, and (d) the inmate has never been convicted of a crime listed under Penal Code Section 667(e)(2)(iv), a.k.a. a “super strike.” As an exception to the criteria, the Unit will also consider sentences where the inmate is serving a sentence for a First Degree (residential) Burglary. FPL and the Unit will conduct a thorough review of the case and of the inmates history in prison, including efforts made towards rehabilitation, to determine if early release is appropriate.
