The body of the Institutional Revolutionary Party, or PRI, candidate for mayor of Guadalupe y Calvo, a city in the northern Mexican state of Chihuahua, was found on a dirt road, officials said.

Jaime Orozco Madrigal's body was discovered Wednesday on a road that leads to Guadalupe y Calvo, Chihuahua Gov. Cesar Duarte said in a press conference.

Orozco Madrigal was kidnapped on Monday night by several gunmen, the Chihuahua Attorney General's Office said.

"Approximately 10 men" took the politician away in an SUV, an AG's office spokesman told Efe.

The state AG's office has launched "an operation to find those responsible and clear up" the politician's killing, Duarte said.

Orozco Madrigal was in full campaign mode ahead of the July 7 local elections and the motive for his killing is unknown.

Guadalupe y Calvo, a city of about 50,000, has been plagued by violence for some time.

Gunmen killed Guadalupe y Calvo Mayor Ramon Mendivil Sotelo on Feb. 17, 2010.

Chihuahua has been one of the states most affected by the wave of drug-related violence in Mexico. EFE
