"It's platinum, palladium, and rhodium. You have platinum for around $800 or $900 dollars an ounce. You have palladium for around $2,200 an ounce. You have rhodium that's $18 to $20,000 an ounce, " said well-known scrap shop owner Dennis Laviage of C&D Scrap Metal.
The issue is that it is impossible for an average person to extract those metals. There's a complicated process that must be done in a manufacturing setting.
Laviage said regulations are already on the books to keep stolen converters from being bought by recyclers. That is why he does not purchase catalytic converters much anymore. He said buying them from sellers requires a lot of paperwork and he won't accept anything stolen.

"There's a lot of bad apples in every business. I don't know who is buying these catalytic converters," Laviage said "I don't know if it's a racket going on. I do know this, there are ways to steal converters and get them out of the city and no one even knows where they went. I think that's probably what is happening."

In an interview with ABC13, Harris County Judge Lina Hidalgo called for statewide restrictions. She said while the county and other local municipalities are trying to crack down on the crime, state lawmakers must intervene.
"I'm going to be bashful about that. We do need the regulation at the state level. I have no reason to believe that my state colleagues would be opposed to. Obviously, we need the state legislature to convene," said Hidalgo.
