Caldwell Police detectives arrested three Canyon County men Wednesday in connection with an organized catalytic converter theft ring that investigators believe is responsible for more than 120 converter thefts across Nampa, Caldwell, and Middleton over the past six months. The arrests followed a two-month undercover investigation conducted jointly by Caldwell Police, the Nampa Police Department, and the Canyon County Sheriff’s Office.
Marcus Rivera, 28, of Caldwell, James Thornton, 31, of Nampa, and Kyle Benson, 25, of Caldwell were each charged with grand theft, conspiracy, and trafficking in stolen property — felonies that carry potential sentences of 14 years in Idaho state prison. All three are being held at the Canyon County Jail in Caldwell with bond set at $75,000 each.
How the Theft Ring Operated in Canyon County
According to court documents, the three suspects operated a systematic theft operation targeting vehicles parked in residential driveways, apartment complexes, and business parking lots throughout Canyon County. Using battery-powered reciprocating saws, the suspects could remove a catalytic converter in under 90 seconds — typically between 2 AM and 5 AM when detection risk was lowest.
The stolen converters, which contain precious metals including platinum, palladium, and rhodium, were sold to an out-of-state metals recycler for $150 to $800 each depending on the vehicle type. Investigators estimate the ring generated approximately $85,000 in illegal proceeds over the six-month period, while causing an estimated $360,000 in repair costs for the 120-plus Canyon County victims who had to replace their stolen converters at $1,500 to $3,000 per vehicle.
Caldwell Police Detective Sarah Morgan, who led the investigation, said the ring specifically targeted Toyota Tacomas, Honda Accords, and Ford F-150s — vehicles with easily accessible converters containing higher concentrations of precious metals. “These aren’t random crimes of opportunity,” Morgan said. “This was a calculated, organized operation that targeted specific vehicles and specific neighborhoods.”
Impact on Canyon County Residents
Catalytic converter theft has been one of the fastest-growing property crimes across Canyon County and the broader Treasure Valley over the past three years, driven by rising precious metals prices and the relative ease of the crime. Victims face not only the replacement cost but also days without their vehicle, increased insurance premiums, and the violation of having their property targeted.
The Caldwell Police Department has received over 200 catalytic converter theft reports in the past 12 months alone, with similar numbers reported to the Nampa Police Department and Canyon County Sheriff’s Office. The crime disproportionately affects working families who rely on their vehicles for daily commutes to jobs across the Treasure Valley and cannot easily absorb a $2,000 repair bill.
Prevention and Legislative Response
In response to the catalytic converter theft epidemic, the Idaho Legislature passed a bill in 2025 requiring scrap metal dealers to maintain detailed records of converter purchases, including seller identification, vehicle VIN numbers, and photographs. Canyon County law enforcement has credited the new tracking requirements with generating leads that contributed to Wednesday’s arrests.
Caldwell Police recommend Canyon County residents park in well-lit areas, consider installing motion-activated cameras, and look into aftermarket catalytic converter locks or cages that cost $150-300 and make removal significantly more difficult and time-consuming for thieves.
What Comes Next
The three suspects are scheduled for preliminary hearings in Canyon County Magistrate Court on April 7. Investigators say the case remains active, and additional arrests are possible. Canyon County residents who believe they were victims of converter theft between September 2025 and March 2026 are asked to contact Caldwell Police at 208-455-3115 with their case numbers. The Canyon County Prosecutor’s office will handle felony proceedings.
