“Television Made Private Investigators Famous. Reality Made Them Necessary.”
Most people think they know what a private investigator does because of television.
Fast cars. Dramatic confrontations. Hidden cameras behind every corner. The “Hollywood detective” who somehow solves every case in 43 minutes.
The reality is very different.
Real private investigation work is rarely glamorous. It is methodical, patient, detail-driven, and often deeply human.
A professional investigator spends far more time:
• reviewing reports and evidence,
• locating witnesses,
• verifying facts,
• conducting surveillance lawfully,
• documenting timelines,
• preserving chain of custody,
• researching records,
• and helping attorneys, insurers, businesses, and families uncover the truth.
Many investigators today come from backgrounds in law enforcement, military service, compliance, insurance investigations, forensic accounting, legal support, or regulatory work. Others specialize in defense investigations, missing persons, tribal matters, civil litigation, fraud, or background investigations.
At Tracey D. Allen Investigations, the work is not about fiction or theatrics.
It is about “facts”.
It is about asking questions others may overlook.
It is about professionalism, ethics, documentation, discretion, and experience.
Sometimes our work helps protect the innocent.
Sometimes it helps expose fraud.
Sometimes it helps attorneys prepare a stronger defense.
Sometimes it simply gives a family answers they have sought for years.
The public perception of private investigators has long been shaped by television stereotypes, but the profession itself is built upon patience, credibility, and trust.
The best investigators are not actors.
They are professionals dedicated to finding the truth wherever the facts lead.

Hiring a Private Investigator in South Dakota: What Clients Should Know

By Tracey D. Allen Investigations

South Dakota is one of the few states in the country that does not require private investigators to hold a state-issued PI license. There are currently no statewide experience requirements, testing standards, or dedicated regulatory oversight specific to the private investigation profession.

While that may surprise many people, it creates an important reality for attorneys, insurance carriers, businesses, and private citizens seeking investigative services:

Not all investigators operate with the same level of professionalism, compliance awareness, documentation standards, or accountability.

Professional investigative work involves far more than simply conducting surveillance or taking statements. Investigators routinely handle sensitive evidence, privacy-related information, litigation support materials, and activities governed by federal and state law — including matters involving the Fair Credit Reporting Act (FCRA), privacy protections, evidence preservation, and lawful investigative practices.

In a state without formal PI licensing standards, clients should perform their own due diligence before hiring an investigator.

Important questions to ask include:

• Is the investigator operating as a properly registered business?
• Does the company maintain an active South Dakota business tax license?
• Does the investigator carry General Liability Insurance?
• Does the investigator understand evidence handling, documentation, and courtroom scrutiny?
• Does the investigator have professional investigative or law enforcement experience?
• Can their investigative methods withstand legal and ethical review?

Poorly conducted investigations can create serious consequences, including compromised evidence, damaged credibility, privacy violations, and unnecessary legal exposure.

At Tracey D. Allen Investigations, we believe professionalism matters — especially in an environment with minimal regulatory oversight.

Our agency maintains:
• Active South Dakota Department of Revenue Business Tax License
• South Dakota License #: 1041-9482-ST
• Business ID: UB288955
• General Liability Insurance
• Professional investigative practices grounded in lawful, ethical, and properly documented investigative work

With over 25 years of investigative and law enforcement-related experience, we understand that investigative work must not only uncover facts — it must also withstand scrutiny.

In today’s environment, experience, accountability, compliance awareness, and professionalism matter more than ever.
