Scam Investigations in South Dakota

01What we see

The Scams South Dakotans Lose the Most Money To

South Dakota's mix of small towns, seasonal tourism and fast suburban growth gives fraudsters several openings. Lincoln County grew more than 18 percent between 2020 and 2025 as Sioux Falls expanded south, and new homeowners there hire contractors, buy furniture online and rent while they build. West River, visitors book Black Hills cabins and campgrounds online. Rural residents rely on phone and internet sellers for things the local store does not stock. Southeast clients often begin with our Tea investigators or Harrisburg team.

The schemes themselves are rarely new. A contractor demands a large deposit and stops answering. A rental listing copies photos from a real property and asks for a wire. A seller ships nothing. A charity solicits donations for a cause it does not support. What makes a case winnable is evidence, and that is what most victims lack when they first call. Our consulting for South Dakota cases starts by sorting what the victim already has from what still needs to be found.

• Contractor deposit and home improvement fraud
• Fake rental and vacation lodging listings
• Online marketplace non-delivery
• Bogus charity solicitations
• Pyramid and recruitment schemes
• Business-to-business misrepresentation

02SDCL 37-24-6

What South Dakota's Deceptive Trade Practices Law Covers

SDCL 37-24-6 is the backbone of South Dakota consumer fraud law. It generally makes it a deceptive act to knowingly use fraud, misrepresentation or concealment of a material fact when selling or advertising merchandise or soliciting charitable contributions, whether or not anyone was actually misled. It also reaches unordered billing, pyramid promotional schemes, misleading price-reduction claims and false going-out-of-business sales. Our corporate malfeasance investigators apply the same statute to larger commercial disputes.

Penalties scale with the amount involved, from a Class 1 misdemeanor for violations under $1,000 up to felonies for larger amounts, and SDCL 37-24-31 generally gives a person adversely affected a civil action for actual damages. Whether a case belongs with the Attorney General, a prosecutor or a private lawyer depends on the facts. We document the representations, the payments and the harm so counsel can decide, and our attorney support services keep the work organized for litigation.

03Home improvement

Contractor Deposit Fraud and Unfinished Work

Contractor fraud follows a pattern. A friendly operator offers a good price on a roof, deck, basement or driveway, asks for a substantial deposit to buy materials, starts briefly or not at all, then stops returning calls. Some move to another county or across the state line and repeat. The Attorney General's consumer division lists construction among its complaint topics. Our investigators build the timeline, and evasive person skip tracing locates contractors who have moved on.

Proving fraud usually means showing intent, and intent shows up in patterns. We search court records, small claims judgments, online reviews and business filings to find other customers, then interview them and compare contracts and payment requests. A company that has collected deposits from a dozen homeowners and finished none of the jobs looks very different from one that ran into a supply delay. When the contractor has assets, our asset investigations help counsel judge whether a judgment can actually be collected.

04Tourism and housing

Rental, Lodging and Black Hills Vacation Scams

Fake rental listings target both people moving to South Dakota and visitors to the Black Hills, Badlands and Mount Rushmore. The scammer copies photos from a legitimate property, posts a lower price and asks for a deposit by wire, payment app or gift card, often claiming to be out of state. Victims arrive to find the property occupied or never listed. We trace the listing, contact details and payment account, and the tenant screening approach we use for landlords works in reverse to verify a landlord.

South Dakota's deceptive practices statute addresses lodging specifically. SDCL 37-24-6 generally prohibits advertising lodging rates that are not actually available, charging a different nightly rate without signed written notice, requiring prepayment or cancellation fees without a written policy, and knowingly failing to disclose mandatory fees such as resort or parking charges at booking. Travelers who were misled can raise those points in a complaint, and our Spearfish investigators handle Northern Hills cases, while Rapid City investigators cover the central Hills.

05SDCL 22-40-8 and 49-31-31

Identity Theft, Impersonation and Spoofed Calls

Many scams depend on borrowed identities. Fraudsters pose as government agencies, utilities, banks or a victim's own relatives, and some open accounts in a victim's name. Under SDCL 22-40-8, obtaining or using another person's identifying information without authorization to deceive or defraud, or accessing their financial resources through it, is generally a Class 6 felony. When someone's personal details are being used against them, our personal information wipe reduces what is publicly available afterward.

Phone-based scams often use spoofed caller ID to look local or official. SDCL 49-31-31 generally makes using spoofed caller ID to defraud, or to display another person's number without permission, a Class 1 misdemeanor, and SDCL 37-24-6 separately addresses misleading caller ID in telephone solicitations. Our cyberbullying investigators and fraud team document call logs, voicemail and payment instructions and look for local accomplices who collect cash or packages. Persistent harassing contacts may also fit SDCL 22-19A-1, which our stalking investigators handle.

06Companies as victims

Scams Aimed at South Dakota Businesses

Businesses face their own fraud. Fake invoices arrive from vendors that do not exist, impersonators change a supplier's bank details by email, unordered directory listings are billed as if they were purchased, and investment pitches overstate returns or hide material risks. SDCL 37-24-6 expressly addresses sending bills for property or services that were never ordered. Our corporate investigations team reconstructs how each request entered the company and who acted on it.

Some business scams start inside. An employee may create a fictitious vendor, steer contracts to a relative or approve payments in exchange for kickbacks. We review approval chains, interview staff and compare vendor records with public filings, and our corporate collusion investigations focus on schemes involving more than one insider. Before signing with a new partner or investor, a due diligence report, priced at $300 for remote work, often prevents the problem entirely.

07Next steps

Reporting a Scam and Taking It to Court in South Dakota

Consumer complaints go to the Attorney General's Division of Consumer Protection at (605) 773-4400, 1-800-300-1986 in state, or consumerhelp@state.sd.us, and the division also offers an online complaint form. Criminal complaints go to local police or the sheriff. Internet-enabled fraud should also be reported to the FBI's IC3. We prepare one consistent evidence package so each agency gets the same facts. Northeast victims frequently work through our Aberdeen team.

Civil recovery is possible when the scammer can be found and has assets. Small claims in magistrate court handles cases up to $12,000, and larger claims go to circuit court, with fraud claims generally subject to a six-year limitations period under SDCL 15-2-13, which counsel should confirm. Serving a scammer can be the hardest step, and Delator coordinates process service in Sioux Falls and statewide with logged, time-stamped attempts and a signed affidavit. When the scammer turns out to owe others too, our lost contact skip tracing helps find co-victims.
