01The economy

How South Dakota's Economy Shapes Corporate Investigations

The ten private establishments that employ the most people in South Dakota include Sanford and Avera hospitals, Monument Health in Rapid City, Smithfield Packaged Meats, Wells Fargo Bank, Daktronics, Amazon and Solventum. Sioux Falls has been a card-banking center since Citibank became a South Dakota-chartered bank in 1981, and Citi, Wells Fargo and First PREMIER each employ more than 1,000 people there. Those employers handle large volumes of money, data and patient records, and our Sioux Falls investigator page covers the metro's internal inquiries.

Beyond the metro, agriculture remains the backbone of the economy, with an estimated $32.5 billion in annual contribution and more than 132,000 jobs in the state's 2019 study. Ethanol plants use more than half of the corn harvest. Grain elevators, co-ops, implement dealers and feedlots move valuable inventory with thin supervision, which makes theft and vendor fraud hard to see until the year-end numbers come in.

The West River economy adds tourism, health care and defense. Ellsworth Air Force Base, near Rapid City and Box Elder, has been selected as the first main operating base for the B-21, with arrivals planned for 2027 and about 1,600 more Airmen expected. That growth brings contractors, housing development and new businesses. Our Box Elder investigation coverage serves employers around the base.

02Losses

Employee Theft, Inventory Loss and Internal Fraud

Most internal losses follow access. A cashier with refund authority, a bookkeeper who reconciles the same accounts she pays, or a yard manager who controls fuel cards can take money for months before anyone notices. Our employee theft investigations start with the records, then move to interviews and, where it fits, surveillance. South Dakota grades theft by value under SDCL 22-30A-17, so documenting the amount accurately matters for any referral.

Physical losses need a different approach. Missing fuel, tools, seed, chemicals or parts at a farm supply store, plant or distribution site often point to a pattern of time and place. Our workplace theft work maps when losses occur, who was on shift and which controls failed, and it can include observation of the site with the owner's permission. Livestock taken from an operation is a felony even at modest values under the same statute.

When a company wants to prevent the next loss rather than solve the last one, a fraud risk audit in South Dakota reviews where billing, payroll, purchasing and inventory are exposed. Audits start at $1,200 and end with a written list of specific control changes, ranked by risk, that management can actually carry out. The audit also tells you which existing controls are working, so money is not spent replacing them.

03Leadership issues

Executive Misconduct, Collusion and Damage Control

Misconduct at the top is harder to investigate because the people involved often control the records, the reporting lines and the timing of any disclosure. Boards, audit committees and outside counsel retain us to look at self-dealing, falsified reports, related-party contracts and expense abuse. Our corporate malfeasance investigations report to whoever commissioned the work, usually counsel, so the findings are not filtered by the people under review.

Purchasing is a common weak point. Kickbacks, inflated invoices, split bids and undisclosed ownership of a supplier can drain a company for years. Our corporate collusion investigations compare vendor records, business filings and relationships against purchasing decisions, and they often find links through shared addresses, family names or registered agents. South Dakota's six-year limitation period for contract and fraud claims under SDCL 15-2-13 can matter when the conduct stretches back.

Once misconduct is confirmed, the work shifts to containment. We document what happened, who knew and which controls must change, and that record supports insurance claims, regulatory responses and civil recovery. Our malfeasance damage mitigation service helps leadership move from discovery to repair without losing the evidence a later lawsuit might need. Timing matters, because the steps taken in the first weeks often shape what can be recovered.

04Workplace complaints

Harassment, Discrimination and Termination Investigations

South Dakota's Human Relations Act, SDCL 20-13-10, prohibits discrimination in employment based on race, color, creed, religion, sex, ancestry, disability or national origin, and it extends protection to interns. Charges must generally be filed within 180 days, and the Division of Human Rights reports that about 90 percent of its charges are employment-related. Our workplace sexual harassment investigations gather statements and documents quickly, while memories and messages are still fresh.

Employment in South Dakota is generally at will under SDCL 60-4-4, but statutes and contract terms can limit a termination, and a decision built on verified facts is easier to defend. Before a firing, an employer may want an independent account of what happened; after one, counsel on either side may need the facts developed. Our wrongful termination investigations look at timing, comparators, documentation and stated reasons.

Hiring is the other end of the problem. Many internal cases start with a person who should have been screened more carefully. A basic employee background check costs $102 as remote work, and a deep-dive check for senior or financial roles costs $300. Employers make the hiring decision; we report verified facts, flag anything that needs confirmation and keep the screening consistent across candidates.

05Transactions

Due Diligence, Partners and Real Estate Risk

Before buying a business, investing in one or taking on a partner, you need to know what the paperwork does not say. Our merger and acquisition due diligence produces a $300 written report on the target's filings, lawsuits, judgments, liens and principals, and field work is added when a site or a reference needs checking in person. Findings are organized so counsel can turn them into representations, warranties or price adjustments.

South Dakota's trust laws add a layer of complexity. The state has no rule against perpetuities, allows certain irrevocable self-settled trusts under SDCL ch. 55-16, and reported more than $800 billion in trust assets in 2024 according to the Division of Banking. That can make ownership hard to trace. Investigators work only from public records and lawful discovery, and our business partner background checks note where a trust or entity blocks the view.

Land and buildings carry their own risks: unrecorded easements, liens, disputed boundaries, prior uses and the people behind a seller entity. Our real estate risk investigations research ownership history and litigation and, where useful, visit the property to confirm what the documents describe. For farm ground and commercial sites alike, those checks usually cost far less than a title or boundary dispute after closing, and they give counsel facts to negotiate with.

06Plants and farms

Equipment Theft, Trade Secrets and Site Testing

Machinery theft is a practical problem in a state built on agriculture and construction. Tractors, trailers, skid steers and tools taken from farms and job sites can move across a state line within hours. Our stolen equipment recovery work follows serial numbers, resale listings, auction records and witnesses, and it gives the owner, the insurer and law enforcement an organized record rather than a list of suspicions.

Information can be worth more than equipment. Customer lists, pricing models, engineering drawings and supplier terms are tempting for a departing manager or a competitor's new hire. Our corporate espionage investigations reconstruct who accessed what and when, interview witnesses and preserve evidence counsel may need for an injunction. We do not access accounts or devices without proper authorization from the owner.

Some companies want to know how their controls hold up before anything goes wrong. Our unannounced shock audits test cash handling, receiving, inventory counts, after-hours access and safety procedures without warning, and they start at $1,200. In winter, preparedness matters as well, because sites can be cut off when I-90 or I-29 closes and outside help is hours away. Findings come with a written list of fixes ranked by risk.

07Outcomes

Reports, Remedies and Choosing a Corporate Investigator

A corporate report has to serve several readers: the executive who decides on discipline, the lawyer who may sue or defend, the insurer evaluating a claim and sometimes a prosecutor. Ours separates verified facts from open questions, cites every source and preserves the underlying documents and media. When counsel commissions the work, reports go to counsel, which helps protect privilege, and our investigative support for South Dakota attorneys explains that arrangement.

Some findings must be explained to the public, a board or employees. When misconduct has to be disclosed, our malfeasance press release service helps prepare a factual statement for counsel's review that says what happened and what the company is doing about it, without speculation or admissions counsel has not approved. The statement is drafted from the verified findings, so it holds up if facts are later tested in court or by the press.

South Dakota has no private investigator license, so companies should vet any firm carefully: experience with workplace investigations, interview documentation, insurance, and a written scope and price. Delator Group is a licensed Tennessee private investigation firm, and its leadership reviews every corporate report before release. To start, send leadership a confidential summary of the problem and the people involved, and we will reply with the questions that shape a scope.

FAQ

Frequently asked questions

Should our attorney hire the investigator?

Often, yes. When counsel commissions an internal investigation, the work is directed by the lawyer and reports go to the lawyer, which helps protect privilege and keeps the inquiry focused on legal issues. Employers who are not yet sure whether counsel is needed can still call us first, and we will say candidly when a lawyer should be involved.

How much do corporate investigations in South Dakota cost?

Field work is billed at $100 per hour. Audits start at $1,200, a due diligence report costs $300 and a basic employee background check costs $102 as remote work. Each matter gets a written scope and total before work starts, and extensions are approved in writing. Our South Dakota investigation cost guide explains how estimates are built.

Can you interview our employees?

Yes. Interviews are usually the heart of an internal investigation. We schedule them through management or counsel, explain who we are and why we are there, take careful notes and summarize them accurately. Employees can decline, and we do not threaten or mislead anyone. Interview plans for harassment matters are set with counsel to respect the complainant and the accused.

What if we suspect a manager is stealing?

Preserve records, limit who knows and avoid confronting the person until the facts are gathered. We start with the documents, such as invoices, refunds, payroll and access logs, then decide with you whether interviews or surveillance are needed. Our employee surveillance service can document conduct outside the office when the evidence points there.

Do you report findings to the police?

That decision belongs to the company and its counsel. We prepare a report organized so a referral is straightforward if you choose to make one, with losses calculated, sources cited and evidence preserved. Some companies prefer civil recovery or termination without a referral. We explain the options and leave the decision to you.

Can you check a company before we buy it?

Yes. A due diligence report covers filings, lawsuits, judgments, liens and the principals behind the target, and costs $300 as remote work. When something needs confirming in person, such as a site, a customer or a reference, field work is added at $100 per hour. Our acquisition risk investigations go further for larger transactions.

How do you handle confidential business information?

We limit access to the people working the file, store materials securely and return or destroy them as agreed. We do not access accounts or devices without proper authorization from the owner. Reports go to the person who commissioned the work, usually counsel. Confidentiality terms can be written into the scope at the start.

Do you investigate agricultural operations?

Yes. Farms, ranches, co-ops, elevators and implement dealers face theft of equipment, grain, fuel and livestock, as well as partner and lease disputes. Investigators who understand rural distances and seasonal schedules plan the work around harvest and calving rather than against them. Our stolen asset tracing covers recovery when property has already left the operation.

Can you serve legal papers on a business?

Delator Field Services coordinates process service statewide. Under SDCL 15-6-4(d)(1), service on a business entity generally goes to an officer, director, partner or registered agent, or, if none can conveniently be found, to the person in charge of an in-state office. Our South Dakota process serving hub explains how service is documented.

How quickly can a corporate investigation begin?

Records review and remote research can often start as soon as the written scope is approved. Interviews and site work depend on schedules and travel, especially for West River locations. If evidence may be lost, such as video that overwrites or a departing employee's files, tell us at intake and we will advise on preserving it immediately.
