Tou Sue Vang was given a 12-year sentence Tuesday for his part in a family-run theft ring, according to acting U.S. Attorney Michele Beckwith.
Prosecutors say Vang, along with his brother Andrew Vang and mother Monica Moua, bought stolen catalytic converters from local thieves and sold them to a buyer in New Jersey for more than $38 million.
“This defendant led a network of criminals that hurt thousands of innocent car owners,” Beckwith said in a statement Tuesday. “This case represents the kind of far-reaching investigation that federal, state, and local law enforcement partners can do when working together.”
Catalytic converters are part of a vehicle’s exhaust system that reduces toxic gas and pollutants from the engine. Stealing them has become popular nationwide because the converters are easy to remove, have no identifying markings, and can fetch more than $1,000 each, according to the U.S. Attorney’s Office in Sacramento.
Buyers want the precious metals inside, including platinum, palladium, and rhodium, the last of which is more valuable per ounce than gold.
Tou Vang’s prosecution is part of a nationwide crackdown on catalytic converter theft.
His case includes his brother and mother, and 12 other defendants from New Jersey.

Federal prosecutors say the defendants operated DG Auto and purchased the stolen converters from California.
Tou Vang and his family operated mostly from their private residences and storage units, according to federal officials. They did not have a scrapyard or a valid business license.
Some of the shipments Tou Vang made to DG Auto weighed over 1,000 pounds and contained a single type of high-value catalytic converter, such as the ones found in Toyota Prius cars.
Tou Vang and his family allegedly used the funds received from the New Jersey defendants to withdraw from bank accounts they controlled to buy more stolen catalytic converters.
Prosecutors claim Tou Vang spent the proceeds of converter sales to fund a lavish lifestyle. He allegedly purchased a five-acre multi-home complex in Rio Linda for $1.235 million in cash; over a dozen motor vehicles, including two Teslas and two Sea Doos; and another home in Sacramento.
As part of Tou Vang’s sentence, he forfeited more than $150,000 in cash, 13 motor vehicles, four personal watercraft, jewelry, real estate, and other property, according to federal prosecutors.
“This takedown is the first of its kind in the nation and a major step forward in dismantling a catalytic converter theft ring,” said FBI Special Agent in Charge Sid Patel of the Sacramento Field Office.
