The Wilmette Police Department welcomed a new team member with unique skills: Gizmo, a Golden Retriever-Labrador mix trained to detect electronics during criminal investigations. Gizmo, who is two years old, joined the department in June. He stands out as one of four K-9s in Illinois and approximately 100 in the nation with this specialized ability.
Gizmo’s handler, Sam Walker, works as a digital forensic analyst at the police department. Gizmo’s arrival was a dream come true for Walker’s family. “My kids wanted a dog and it worked out pretty well,” Walker stated. “I do a lot of digital forensics, so it was just a natural fit.” Initially, Gizmo was trained to serve as a service dog but did not complete the program due to behavior issues. This rerouted him to the Jordan Detection K-9 Electronic Storage Detection program in Indianapolis, which focuses on scent detection of chemical compounds in electronics.
Gizmo assists investigations by identifying electronics, such as laptops and USB drives, swiftly.
After completing the program, Walker took a handler certification course at the National Computer Forensic Institute in Alabama. Gizmo’s Labrador mix breed is known for its keen sense of smell, making him exceptional in this field. The ability to detect any electronics storing data, such as laptops, USB drives, and Micro SD cards, empowers Gizmo to excel in his responsibilities.
The Jordan Detection agency highlights that electronic detection K-9s can accelerate evidence recovery in cases like child exploitation, terrorism, and white-collar crime. “Leveraging the acute olfactory abilities of the K9s, investigators can locate electronic devices, even those damaged by fire or concealed within debris,” according to their website.
Gizmo swiftly locates hidden electronics, reducing the time officers spend on searches. Chief of Police Michael Robinson shared that Gizmo identifies these devices by detecting chemicals used in electronic adhesives. “He’s assisted neighboring police agencies and successfully found evidence,” Robinson noted. Additionally, Gizmo’s training and travel costs were covered by the United States Secret Service, leaving Wilmette responsible for food and care, estimated at $2,400 annually.
In his dual role, Gizmo also functions as a comfort dog, easing stress for officers and the public, including victims, children, and families in crisis. Walker explained, “The social work office is next to mine. If they have someone who’s nervous, Gizmo can interact with them, allowing them to relax and communicate better.” Gizmo is showcased at community events, where people inquire about his whereabouts.
“He’s very much becoming a vital resource for our department,” Robinson said. “People keep asking, ‘Where’s Gizmo?’”
