All five suspects are charged with engaging in organized criminal activity.
The fencing allegation implies that the five theft ring suspects knowingly bought stolen goods in order to later resell them for profit.

The catalytic converter theft ring bust involved the execution of six state search warrants at three residences and three commercial properties in the Pearland area.
On Wednesday, authorities seized more than 1,450 stolen catalytic converters, about $840,000 in illicit proceeds, five vehicles, and various equipment believed to be used for criminal activity.
The stolen converters and oxygen sensors are worth a total of about $4.3 million, officials said.
Detectives said their investigation started earlier this year and has expanded as an organized theft ring has emerged.
Police raided three homes and three businesses, including a busy alterations shop in Pearland.
The operation comes after months of catalytic converter thefts across Houston and the surrounding areas.

In some cases, the thefts have turned deadly.
In July, six other people were arrested in connection to a theft ring also linked to the death of Almendarez.
A month before the arrests, a new ordinance in Houston went into effect to crack down on catalytic converter thefts and resale.
The ordinance was unanimously approved back in May.
As part of the law, people will now need to show proof of owning a cut catalytic converter when they go to sell it to a metal recycler.
