At Cross Point Solutions, we understand that truth verification is only as strong as the information we collect and validate. Polygraph examiners rely on accurate, well-documented details to conduct effective exams. That’s where private investigators (PIs) play a crucial role. Their expertise in gathering intelligence, conducting surveillance, and uncovering key facts can be the difference between a breakthrough confession, an undisputed truth, or—perhaps most importantly—proving someone’s innocence.
This article explores how we’ve successfully integrated private investigators into our truth verification process and why they serve as invaluable assets to polygraph examiners. If you’re considering working with a PI, we highly recommend partnering with experienced professionals. Personally, I have worked with and trusted Chad at Assurance Investigations—an exceptional resource for investigative services in Colorado.
Strengthening Polygraph Examinations with Private Investigators
While polygraph examinations are powerful tools for detecting deception, their effectiveness is amplified when paired with skilled investigative work. Private investigators bring critical insights, background intelligence, and actionable evidence that help polygraph examiners refine their approach and improve accuracy.
Pre-Polygraph Investigation: Laying the Groundwork
Before a polygraph session even begins, private investigators can conduct thorough background checks on the subject. This process includes:
Verifying the individual’s history
Identifying potential motives for deception
Gathering critical case details
By providing this preliminary intelligence, PIs help examiners craft more effective and relevant questions tailored to the unique circumstances of each case. Additionally, they can uncover red flags, such as prior criminal behavior, deceitful tendencies, or known associations that could influence polygraph results. If a subject has researched ways to manipulate the exam, a PI may detect these attempts beforehand.
Surveillance and Evidence Gathering: Providing Key Context
PIs are experts in surveillance and evidence collection, which is invaluable in cases involving fraud, theft, infidelity, or other misconduct. By securing video footage, photographic evidence, or witness testimony before the exam, they enable polygraphers to ask targeted, high-stakes questions that increase the likelihood of detecting deception.
For example, in an employee theft investigation, a PI might uncover security footage that contradicts the suspect’s statements. This type of evidence allows the examiner to probe deeper, leading to stronger, more conclusive results.
Interviewing and Behavioral Analysis: A Strategic Advantage
Private investigators are trained in interviewing techniques and behavioral analysis—both of which complement polygraph examinations. A PI can conduct initial interviews to assess a subject’s credibility, observing body language, inconsistencies, and psychological cues before the test.
If a subject fails the polygraph, PIs can step in with follow-up interviews and additional investigative efforts to get to the truth. This collaborative approach ensures that even if polygraph results are inconclusive, the investigative process continues.
Legal and Ethical Considerations: Strengthening Cases
While polygraph results alone may not always be admissible in court, combining them with a PI’s legally obtained evidence creates a compelling case. Whether assisting attorneys, law enforcement, or corporate security teams, private investigators can provide supporting documentation, witness testimony, and surveillance reports that bolster polygraph findings.
Post-Polygraph Investigations: Digging Deeper
A polygraph exam isn’t always the final step—sometimes, it’s just the beginning. If deception is detected, PIs can continue the investigation, gathering additional proof through financial records, digital forensics, or extended surveillance. Conversely, if an individual passes the polygraph but doubts remain, a PI can conduct further inquiries to ensure no critical details were overlooked.
