A federal indictment unsealed Monday charges former Tamaulipas governor Tomas Yarrington Ruvalcaba, 56, and Mexican construction firm owner Fernando Alejandro Cano Martinez, 57, with conspiring to violate the Racketeer Influenced and Corrupt Organizations (RICO) Act.

The two are also accused of conspiracy to launder money, conspiracy to defraud, and conspiracy to make false statements to federally insured U.S. banks. A federal grand jury in Brownsville returned the indictment in May, and it was unsealed Dec. 2, according to an August press release from Immigration and Customs Enforcement.

The charges were announced by U.S. Attorneys Kenneth Magidson of the Southern District of Texas and Robert L. Pitman of the Western District of Texas.

The case is the result of a multi-agency probe involving ICE Homeland Security Investigations, the DEA, IRS Criminal Investigation, the FBI, and the Texas Attorney General’s Office, the release said.
