Three suspects were arrested by the Federal Police in connection with the murder of Jose Eduardo Moreira Rodriguez, son of former Coahuila Gov. and Institutional Revolutionary Party, or PRI, chairman Humberto Moreira, the Mexican Public Safety Secretariat said.

Victor Landeros Sifuentes, Jorge Tenorio Takajasi and Roberto Clemente Barcenas Cepeda were arrested on Monday in Saltillo, the capital of the northern state of Coahuila, thanks to intelligence and surveillance work, the secretariat said.

The suspects had been wanted since Oct. 7 for the kidnapping and murder four days earlier of Moreira Rodriguez on a rural road in Ciudad Acuña near the U.S.-Mexico border.

Landeros Sifuentes worked as a supervisor for the police department in Ciudad Acuña and allegedly kidnapped Moreira Rodriguez, the secretariat said.

The 30-year-old Landeros Sifuentes provided protection to members of the Los Zetas drug cartel, the secretariat said.

The suspect told investigators that he was in touch with Ciudad Acuña deputy police operations director Rodolfo Castillo Montes, who was the direct boss of those involved in the killing, on Oct. 3, the day of the murder.

Landeros Sifuentes said he and Castillo Montes contacted the victim and asked him to meet them at a convenience store.

Moreira Rodriguez met the police officers at the agreed upon location and was handed over to Carlos Arnulfo Flores Flores, who runs the Zetas drug cartel's business in the area, and Ruben Sifuentes Cadena, who took the victim away.

Moreira Rodriguez's body was found a few hours later, the secretariat said.

Tenorio Takajasi, a 41-year-old Ciudad Acuña police officer, told investigators that he and Landeros Sifuentes handed Moreira Rodriguez over to the drug cartel.

Clemente Barcenas, 30, provided Landeros Sifuentes and Tenorio Takajasi with food and a place to hide, the secretariat said.

Coahuila Attorney General Homero Ramos Gloria said in a radio interview a few days after the murder that municipal police officers in Ciudad Acuña were implicated in the crime but refused to provide further information that might interfere with the investigation.

Ramos also referred to the possibility that Moreira Rodriguez's murder was an act of revenge for the killing of the nephew of Los Zetas drug cartel boss Miguel Angel Treviño Morales, alias "Z40," in a shootout with state police in the border city of Piedras Negras.

The 25-year-old Moreira Rodriguez was regional coordinator of social development programs for the violence-wracked state of Coahuila, whose governor, Ruben Moreira, is Moreira Rodriguez's uncle.

Humberto Moreira, who served as Coahuila's governor from 2005 to 2011, became PRI chairman after leaving office.

He resigned on Dec. 2, 2011, amid a scandal over allegedly improper contracting during his time as governor of that state.

Moreira's resignation was prompted by statements made a day earlier by President-elect and then-candidate Enrique Peña Nieto, a member of the PRI, that the controversy over the surge in Coahuila's public debt had hurt the party. EFE
