Private Corporate Investigations: Monitoring Property, Preventing Theft and Protecting Your Business

Businesses and organizations do not always know when a security problem is developing. Sometimes the warning sign is missing inventory, damaged property or an employee using company equipment in an unauthorized manner. In other situations, the concern may involve a vacant property, a fire-damaged site, suspicious activity after hours or a contractor who is not performing the work that has been reported.

Private corporate investigations can provide businesses, municipalities and other organizations with an additional resource when they need someone to monitor a property, document activity, investigate suspected theft or determine what is actually happening.

At Duncan Investigations, we can assist with much more than traditional surveillance. Depending on the circumstances, our investigators can monitor properties, conduct undercover loss-prevention operations, investigate employee misconduct, document theft and vandalism, investigate municipal concerns, conduct corporate surveillance and gather evidence that can help management make informed decisions.

Monitoring Your Property When You Cannot Be There

There are many situations where a business owner or organization needs someone on the ground to monitor a property but does not necessarily require a permanent security presence.

A property may be vacant, under construction, damaged, closed temporarily or subject to an ongoing problem. Management may be located in another city or simply unable to be present during the hours when concerns are most likely to arise.

Investigative surveillance can provide an independent set of eyes on the property.

An investigator may document vehicles arriving and leaving, people entering or leaving the property, activity around restricted areas, removal of property, suspicious behaviour, vandalism or other circumstances relevant to the assignment.

The purpose is not simply to watch the property. It is to document what is happening and provide the client with useful investigative information and physical evidence.

Monitoring a Fire-Damaged or Vacant Property

Fire-damaged properties can present unique security concerns. Once a building has been damaged, it may be vacant or partially secured, while valuable contents, equipment or materials remain inside or around the property.

A property owner, insurer, municipality or other authorized party may need the site monitored to identify unauthorized entry, suspicious activity, vandalism or removal of property.

For example, a commercial building suffers a significant fire and must remain vacant while repairs and insurance matters are being addressed. The owner is concerned that people may enter the property after hours or that remaining equipment and materials may be removed.

Investigative surveillance can provide monitoring of the site during specified periods and document activity occurring around the property. If suspicious individuals or vehicles attend, the investigator can record relevant observations and provide a factual report.

This type of assignment can be particularly useful when a property is vulnerable but a continuous security contract is not practical or necessary.

Construction Site Monitoring

Construction sites can contain thousands of dollars in tools, equipment, copper, fuel, building materials and machinery. They may also be accessible to numerous employees, contractors and subcontractors.

When repeated theft occurs, the challenge is often determining when and how the property is being removed.

For example, a construction company discovers that copper and expensive tools are repeatedly disappearing from a site. The company has security cameras but cannot determine exactly when the losses are occurring. Duncan Investigations can conduct targeted surveillance during periods identified as higher risk, document vehicles and individuals attending the site and help establish a pattern.

The information may allow the company to determine whether the problem is occurring after hours, during deliveries, during shift changes or while particular contractors are present.

Undercover Loss Prevention in Retail Stores

Retail loss prevention is another area where private investigators can provide specialized assistance.

A store may have concerns about employee theft, unauthorized discounts, fraudulent returns, cash shortages, merchandise being removed without payment or employees providing products to customers without properly recording the transactions.

An undercover investigator can, where appropriate and lawfully authorized, enter a retail establishment as an ordinary customer and observe how transactions are handled.

For example, a retailer sells high-value electronics. Management discovers that inventory records repeatedly show shortages involving expensive products, while corresponding sales cannot be located in the company's records.

An appropriately planned undercover operation may involve an investigator making an authorized purchase and documenting whether the employee processes the transaction correctly, provides a receipt and accounts for the merchandise and payment.

The purpose is of the investigation is to determine whether suspected conduct can be independently documented.

When the undercover transaction is compared with inventory records, point-of-sale information and cash reconciliation, the business may be able to establish a much clearer picture of what is occurring.

Employee Theft Investigations

Employees often have legitimate access to company property, which can make internal theft particularly difficult to detect.

A company may discover missing tools, equipment, merchandise, fuel or cash but have no direct evidence identifying the source of the loss.

For example, a business notices that expensive tools are repeatedly disappearing from a company warehouse. Management determines that the losses appear to occur during certain shifts. Rather than immediately accusing an employee, the company can engage an investigator to examine the circumstances and conduct appropriate surveillance.

The investigation may establish that the missing equipment is being removed from the property, identify relevant patterns and provide evidence that can be compared with inventory records and employee schedules.

Employee Misuse of Company Vehicles

Company vehicles can also become the subject of corporate investigations.

An employee may be suspected of using a company truck for unauthorized personal business, performing outside work while being paid by the employer, transporting company property for an unauthorized purpose or using company equipment contrary to workplace policies.

For example, a company discovers that one of its trucks is accumulating substantially more mileage than expected. Management also receives information that the employee may be performing private work using company equipment.

Surveillance may document where the company vehicle travels, where it stops and what activities occur. The resulting evidence can then be compared with company records and the employee's assigned duties.

Employees Working for Competitors or Conducting Unauthorized Outside Work

Businesses can also encounter concerns involving employees who operate competing businesses or perform outside work during company time.

An employee may be using company vehicles, equipment, tools, customer contacts or other resources to operate a private business.

For example, a company receives information that an employee is using a company vehicle to perform paid work for private customers during hours when the employee is supposed to be working for the employer.

Surveillance can potentially document the activity, including the use of company property and the circumstances surrounding the work.

The investigator does not determine whether the employee has breached an employment agreement or whether termination is justified. The role is to establish and document the facts so the employer and, where appropriate, legal counsel can make that determination.

Municipal Investigations

Private investigators can also provide investigative services to municipalities and other public organizations.

Municipalities may encounter concerns involving vacant properties, illegal dumping, property damage, unauthorized use of municipal assets, bylaw-related investigations, suspicious activity, contractor compliance and other matters where independent evidence is required.

For example, a municipality may receive repeated complaints about illegal dumping at a particular location. Signs have been posted, but the dumping continues and the municipality does not know who is responsible.

Investigative surveillance can be used to monitor the location during appropriate periods and document vehicles, individuals and activity associated with the dumping.

Another example could involve a municipal property that is repeatedly being accessed after hours. An investigator may be assigned to determine who is attending the property and document the circumstances.

These investigations can provide municipalities with information that may assist in enforcement decisions or further investigative action.

Municipal Property and Equipment

Municipalities have significant investments in vehicles, equipment, buildings and infrastructure.

Concerns may arise when equipment is damaged, missing, misused or accessed without authorization.

For example, a municipality may discover that fuel consumption at a particular facility is significantly higher than expected. An investigation could examine whether there is an operational explanation, whether unauthorized use is occurring or whether further investigation is warranted.

Similarly, surveillance may be used to investigate suspected misuse of municipal vehicles or equipment where there is a legitimate investigative purpose.

Contractor and Vendor Investigations

A business or municipality may pay a contractor to perform specific work but later question whether the work was actually completed as reported.

For example, a company contracts a service provider to maintain several properties. Management begins receiving complaints that certain locations are not being serviced despite invoices being submitted.

An investigator may conduct surveillance to establish whether workers attend the properties, when they arrive, how long they remain and whether observable activity corresponds with the contracted work.

The investigation does not replace a contractual or legal assessment. Instead, it provides factual information that management can use when reviewing the contractor's performance.

Workplace Investigations

Not every corporate investigation involves theft.

Employers may need assistance investigating allegations of misconduct, unauthorized activities, misuse of company property, conflicts of interest, workplace concerns or violations of company policies.

For example, an employer may receive information that an employee is regularly leaving the workplace during paid working hours to conduct another business.

Another employer may suspect that an employee is using company equipment for private work.

In these situations, surveillance can provide independent evidence concerning the employee's activities.

Monitoring Property After Vandalism or Repeated Damage

Repeated vandalism can become expensive and frustrating for property owners.

A business may experience broken windows, damaged equipment, graffiti, unauthorized entry or repeated damage to vehicles and buildings.

If the incidents continue despite repairs or security measures, surveillance may help determine whether there is a recurring pattern.

For example, a commercial property experiences repeated damage to its exterior after midnight. The owner installs cameras but has difficulty identifying the person responsible.

Targeted surveillance during relevant periods may provide another layer of observation and potentially establish information that can be compared with camera footage and

previous incidents.

Theft Prevention Is More Than Watching the Door

A business experiencing theft may immediately consider hiring additional security guards. Security personnel can provide an important deterrent, but businesses should also ask whether they understand how their losses are occurring.

If inventory is disappearing, the important questions may include where the merchandise is being lost, when the losses occur, who has access, whether transactions are being properly recorded and whether there are weaknesses in the company's procedures.

An investigator can approach the problem from an evidence-gathering perspective.

That may involve reviewing records, conducting surveillance, performing an undercover operation, examining existing security footage or investigating employees, contractors or other individuals who may have access to the property.

Combining Security, Surveillance and Investigation

The most effective approach is not always to choose between security and investigation.

A business may continue using cameras, alarms and security personnel while also engaging a private investigator to address a specific problem.

Security may deter unauthorized activity. Cameras may record what occurs. An investigator can analyze the circumstances, conduct targeted surveillance and gather additional evidence. We can monitor areas during specific times when theft is high.

This combination can help a business move from simply reacting to incidents toward understanding the source of its losses.

Why Independent Evidence Matters

When an employer or organization suspects theft or misconduct, it is important to separate suspicion from evidence.

An investigator can document dates, times, locations, vehicles, individuals, transactions and observable conduct. Information obtained from the client can be identified separately from information independently observed during the investigation.

This creates a clearer investigative record. It can also help protect employees and other individuals from being incorrectly accused when the evidence does not support the allegation.

Sometimes an investigation confirms the client's concerns. Other times, it reveals that the original assumption was incorrect and that the real problem lies somewhere else.

Both outcomes are valuable.
