A federal judge set bond at $1 million for a South Texas man. The man is tied to a border case linked to the Gulf Cartel. His name is Rigoberto Brown. He is from Brownsville, Texas. Brown walked out of jail about 48 hours after his bond hearing.

Brown was a fugitive in Mexico. He hid there for almost four years. He turned himself in this month. He crossed at the Anzalduas Port of Entry near Mission, Texas. In Mexico, people also call him Rigoberto Blanco Cantu. He holds U.S. and Mexican citizenship.

This case matters to the Rio Grande Valley. It is about a business scheme at the border. Prosecutors say the scheme used threats and violence. They say it had ties to a man linked to Gulf Cartel leaders.

A grand jury in Houston charged Brown on December 6, 2022. He was 38 years old at the time. He faces two federal charges. Both come from the Sherman Act. That law bans unfair deals between businesses. One charge says he helped fix prices. The other says he helped run a monopoly. Each charge can bring 10 years in prison. Each can also bring a $1 million fine.

Prosecutors say Brown had manager jobs. He worked for a man named Carlos Favian Martinez. Court records call Martinez the son-in-law of an old Gulf Cartel boss. That boss is Osiel Cardenas Guillen. Martinez already pleaded guilty. A judge gave him 11 years in prison in June 2025. He also got a $2 million fine. U.S. Attorney Nicholas Ganjei said the sentence "reflects the size and scope of his criminal operation."

Prosecutors call the scheme "the Pool." They say it ran from 2011 to late 2022. The Pool used forwarding agencies. These are shops that help "transmigrantes." Transmigrantes are people who move used cars through Mexico. They sell the cars in Central America. This trade is a big part of border life. Many South Texas families work in it.

Prosecutors say the Pool group fixed prices. Agencies had to split profits by set shares. The group also charged extra fees. They call this fee a "piso." Cars paid the piso to cross the Los Indios bridge. That bridge leads into Matamoros. A piso works like a toll. But no government sets it.

Court papers say the group used threats. They say the group used violence too. This forced agencies to obey. Prosecutors say the threats hit owners and workers. They also hit workers' families. One owner paid over $80,000. He tried to work outside the Pool, court records say.

Two federal agencies worked the case. They are Homeland Security Investigations and the FBI. Two offices are prosecuting it now. They are the Justice Department's Antitrust Division and the U.S. Attorney's Office in South Texas.

The Los Indios bridge sits in Cameron County. That is east of other Rio Grande Valley bridges. Transmigrante traffic is a big business here. It moves many used cars into Mexico each year. Court records say cartel ties gave the Pool group control. They held that control for years, with little pushback.

Brown went to federal court in Houston. The judge set his bond at $1 million. Court rules also set a cash part. Brown had to pay $500,000 in cash. His wife paid that cash for him. Brown walked free about two days later.

Two more people in the case are still fugitives. Their names are Miguel Hipolito Caballero Aupart and Diego Ceballos-Soto. Eight other co-defendants already got their sentences.

Brown's case shows how slow these cases can move. He was first charged in 2022. Agents did not catch him until this month. He chose to turn himself in at a Texas border crossing.

It is not clear when Brown will go to trial. It is also not clear if he has a lawyer yet. El Tejano will keep watching this case in federal court.
