Theft costs Michigan businesses and individuals millions of dollars each year – and most of it goes undocumented because the evidence was never properly gathered. Eye Spy Detective Agency conducts theft investigations throughout Michigan for businesses, employers, attorneys, and individuals who need documented proof of what happened and who was responsible. Our investigators are licensed, our methods hold up in court, and every case is handled with complete confidentiality.

Employee Theft Investigations
Employee theft is the most common reason businesses contact Eye Spy for a theft investigation. It takes many forms – cash skimming, inventory theft, unauthorized use of company assets, and payroll fraud among them. The challenge for most business owners is that suspicion alone is not enough. Confronting an employee without documented evidence creates liability and rarely results in recovery.
Eye Spy investigators build the case before you make a move. We conduct covert surveillance, review activity patterns, and document incidents in a format that supports termination, civil recovery, and criminal referral when warranted.
Embezzlement Investigations
Embezzlement involves the deliberate misappropriation of funds by someone entrusted with access to them – a bookkeeper, an office manager, a business partner, or an executive. It tends to go undetected for months or years because the person responsible controls the records.
Eye Spy works with businesses and their legal counsel to document financial discrepancies, identify patterns of misappropriation, and gather evidence that supports both civil recovery and criminal prosecution. If you suspect someone inside your organization is stealing from it, the time to act is before they cover their tracks.
Retail and Inventory Theft
Retail businesses face theft from two directions: shoplifters and their own employees. Organized retail theft has increased significantly across Michigan in recent years, and internal inventory shrinkage often goes unaddressed because management lacks the evidence to act.
Eye Spy provides undercover investigators who can work within a retail environment to identify theft patterns, document incidents, and build a case strong enough to support termination or prosecution. We also conduct external surveillance for businesses experiencing organized shoplifting or after-hours theft.
Workers’ Compensation Fraud Investigations
When an employee claims an injury they did not sustain – or exaggerates the extent of a real one to extend a leave or avoid returning to work – the cost falls on the employer and their insurance carrier. Workers’ compensation fraud is one of the most common forms of theft from businesses in Michigan.
Eye Spy conducts covert surveillance on claimants to document activity that contradicts the claimed injury or limitation. Our investigators produce written reports and video evidence that insurance carriers and attorneys can use to challenge fraudulent claims and recover costs.
Who Calls Eye Spy for Theft Investigations
Theft investigations serve a range of clients – not just large corporations. Common situations that lead businesses and individuals to call Eye Spy include:

Common Questions About Theft Investigations in Michigan
Can a private investigator gather evidence of employee theft that holds up in court?
Yes. Licensed private investigators in Michigan can conduct covert surveillance, document activity, and produce written reports and video evidence that is admissible in civil and criminal proceedings. The key is that the evidence is gathered lawfully by a licensed investigator – which is why hiring a licensed firm matters.
How does Eye Spy investigate suspected employee theft?
The approach depends on the situation. Common methods include covert surveillance of the employee during work hours, undercover operatives working within the business environment, review of documented activity patterns, and coordination with the client’s legal counsel. Eye Spy will discuss the most effective approach for your specific situation when you call.
Can you investigate theft that has already occurred, or only ongoing theft?
Both. For ongoing theft, surveillance is typically the most effective tool. For theft that has already occurred, Eye Spy can assist with documenting what happened, identifying patterns, locating evidence, and supporting the civil or criminal case your attorney is building.
How long does a theft investigation take?
It depends on the nature of the case and what evidence is needed. Some investigations produce usable documentation within days. Others require sustained surveillance over several weeks. Eye Spy will give you a realistic assessment of timeline and cost when you discuss your case.
