Jury Pool Research in South Dakota

01How panels are built

Where South Dakota Jurors Come From

Under SDCL 16-13-4.1, the state court administrator's office builds the jury selection list electronically each year from the current voter registration list, supplemented by people 18 and older who hold a valid driver license or state nondriver identification card, with duplicates removed. Each county's master jury list is then drawn at random from that list under SDCL 16-13-9.1 and 16-13-9.2. The statute also says the jury selection list may not be distributed, sold or duplicated for any other purpose, which is why our research begins only with the panel information the court actually provides to counsel.

Qualification is set by SDCL 16-13-10: a juror must be a South Dakota citizen and resident of the county or jury district, at least 18 by January 1 of the year of service, of sound mind and able to read, write and understand English. A felony conviction disqualifies a person unless civil rights have been restored. Under SDCL 16-13-15 the clerk checks qualifications and removes anyone disqualified or who served in the past two years. Our criminal defense investigators sometimes find that a seated juror's record does not match what the qualification process assumed.

02Professional rules

Ethical Boundaries for Juror Research

Juror research is governed by the lawyer's professional obligations, and an investigator working for counsel is bound by the same limits. The American Bar Association's Formal Opinion 466 concluded that lawyers may review the public social media presence of jurors and prospective jurors, that sending an access or friend request is an improper communication, and that a juror's automatic notification that someone viewed their profile is generally not a communication by the lawyer. South Dakota's version of the rule on impartiality and decorum of the tribunal restricts communication with jurors, and individual judges may impose additional limits by order.

In practice, we never contact a juror, never create accounts to see private content, never follow a juror physically and avoid platforms that notify users of profile views unless counsel approves. Every engagement letter names the supervising attorney, and the research plan is reviewed against any standing or case-specific order before work starts. Lawyers who want a refresher on investigator limits more broadly can review our guide to what investigators may lawfully do in South Dakota.

• Passive review of public information only
• No friend, follow or access requests
• No physical surveillance of jurors
• Research plan checked against court orders

03Sources

What a Venire Profile Includes

Each profile starts with identity confirmation, because common surnames in rural counties make it easy to attach the wrong person's history to a prospective juror. We then search the Unified Judicial System's public criminal summaries, civil filings since 2006 and federal court indexes for prior lawsuits, judgments, bankruptcies and criminal matters. A juror who was once sued by an insurer, named in a medical malpractice case or involved in a farm foreclosure may have experiences directly relevant to the case, and counsel can explore them in voir dire.

Public online activity often reveals more than court records. We review publicly visible posts, comments on local news pages, business affiliations, community groups and public statements about topics in the case, such as law enforcement, large employers or tribal relations. Findings are summarized with screenshots and dates so counsel can evaluate them quickly. Our witness background research uses the same identifier discipline, and the two services are often run together before trial.

04Local dynamics

Small Counties, Shared Connections and Venue

South Dakota's population is concentrated in a few counties. Minnehaha has about 212,700 residents and Pennington about 116,800, while counties such as Jones, Hyde and Sully each have fewer than 1,500 people. In a small county, a prospective juror may know the defendant's family, buy feed from a party's business or attend church with a witness. Those connections are not always volunteered, and identifying them before voir dire lets counsel ask the right follow-up questions rather than relying on a general show of hands.

The same dynamics shape venue strategy. Pretrial publicity in a local paper or on community social media can make an impartial jury hard to seat, and documenting the scope of that coverage supports a motion for change of venue or a response to one. We compile coverage, public comments and community ties in a form counsel can attach to a motion. For trials in the Black Hills, our Rapid City investigators are familiar with how news spreads between Rapid City, Sturgis and Spearfish.

05Federal court

Federal Juries and Cases Arising in Indian Country

The U.S. District Court for the District of South Dakota sits in Sioux Falls, Rapid City, Pierre and Aberdeen, and its jury divisions draw from wider areas than a single county. Because South Dakota is not a Public Law 280 state, many serious crimes arising in Indian country are prosecuted federally, and the U.S. Attorney's Office reports that 50 to 60 percent of its criminal caseload involves Indian country offenses. Federal panels in those cases may include both tribal members and non-Native jurors from surrounding counties.

Researching a federal panel calls for sensitivity to community relationships, prior experiences with tribal and federal law enforcement and public statements about jurisdiction disputes. We report only what the public record shows and avoid characterizing anyone by background. Federal judges often limit the information released about prospective jurors and the time available to use it, so we plan the work to fit the court's schedule. Defense teams handling federal matters can read about our felony defense investigations for the broader trial preparation we provide.

06Timing

Working Within the Court's Timeline

Juror information is usually released close to trial, sometimes only a day or two before selection and sometimes on the morning of voir dire. We prepare in advance by agreeing on the case themes that matter, building the research template and lining up staff so work starts the moment counsel receives the list. For large panels, profiles are prioritized so counsel sees the most significant findings first. Turnaround depends on the panel size and the court's release schedule, and we do not promise results in hours.

During trial, some courts allow continued monitoring of seated jurors' public activity for signs of misconduct, such as posting about the case. We do that only at counsel's direction and within any limits the judge sets. If a juror's public posts suggest a problem, counsel decides whether to raise it with the court. Our investigative consulting team can also help design supplemental juror questionnaires where the court allows them.

• Template and themes agreed before release
• Profiles prioritized for large panels
• Trial monitoring only at counsel's direction

07After the verdict

Investigating Possible Juror Misconduct or Nondisclosure

Occasionally, information surfaces after a verdict suggesting that a juror concealed a relationship, misrepresented their background during voir dire or consulted outside information. A focused investigation can test those claims against public records and admissible sources. Post-verdict inquiries are delicate: courts tightly restrict contact with discharged jurors and limit what can be used to challenge a verdict, so the research plan must be built with counsel around the governing rules and any court order.

Our role is to establish facts from records and permitted sources, not to approach jurors. If research confirms, for example, that a juror failed to disclose a lawsuit against a party, counsel receives documented findings suitable for a motion. Civil litigation support carries a $1,000 minimum, with work beyond that billed at $100 an hour. Our wrongful death investigations and other trial services show how juror work fits within full case support, and our South Dakota investigation pricing lists every rate. Each phase of jury pool research in South Dakota is planned and approved by the supervising attorney.
