In November 2018, Idaho law enforcement agencies, including the Idaho Internet Crimes Against Children (ICAC) task force, launched “Operation Grand Canyon,” a sting operation aimed at apprehending individuals suspected of sex solicitation crimes. This case study explores how EyeDetect, a lie detection technology, was instrumental in the success of the operation.

The Challenge

Traditionally, suspects apprehended in such operations claim that the incident is their first offense. Questioning suspects on-site, at the time of arrest, regarding additional previous offenses using polygraph tests was not feasible. The challenges included the difficulty of finding enough trained polygraph examiners available after hours, the need for a lie detection test faster than the standard 2-3 hour polygraph exam, and the requirement to get immediate results.

Implementing EyeDetect

EyeDetect was chosen for its unique advantages: it’s automated, doesn’t require an examiner, the investigative test only takes 15 minutes, and the results are available within 5 minutes. An agent involved in the operation highlighted that EyeDetect provides unbiased, accurate data that can be used in a follow-up interview to elicit a confession. He stated that EyeDetect was used during Operation Grand Canyon to determine whether any sexual contact with minors had occurred since the suspect became an adult.


According to a Nov. 5, 2018 article in the Idaho Statesman, 11 people were arrested as a result of the operation. Seven suspects now face prosecution for state charges, and four have been referred for federal charges. Many of the suspects tested with EyeDetect failed and then confessed to something during the post-test interview. The ICAC team could then test them again, focusing on: “Other than what you’ve already revealed, have you had any sexual contact with a minor since you became an adult?”

Return on Investment

EyeDetect provided Idaho law enforcement officials with the ability to quickly and accurately test suspects on-site. This not only saved time and resources but also allowed for immediate action based on the results.

Operation Grand Canyon serves as a potent example of how EyeDetect can be utilized in real-world law enforcement scenarios. The speed, accuracy, and immediacy of EyeDetect offer significant advantages over traditional polygraph tests, particularly in time-sensitive and resource-limited situations. The integration of EyeDetect into law enforcement practices can lead to more efficient operations and improved outcomes in the fight against sex solicitation crimes.
