Mexican candidate, his wife and 2 sons killed

VILLAHERMOSA, Mexico — Gunmen killed a state congressional candidate and his wife and two sons in their home Saturday in the Gulf coast state of Tabasco, in southern Mexico.

Jose Francisco Fuentes Esperon, 43, was found dead along with his wife, 38, and two sons aged 9 and 13, in the state capital, Villahermosa, according to state Attorney General Rafael Gonzalez Lastra.

Fuentes Esperon was a former university rector, and was widely known in the state capital.

The state government immediately offered to provide protection for any candidate who wants it ahead of Oct. 18 elections.

Gonzalez Lastra said in a statement that President Felipe Calderon called Tabasco Gov. Andres Granier “to express his support and stress his decision to help in investigating the case to the end.”

“There are no words to express these events. We are deeply moved and at the same time indignant,” Gonzalez Lastra said.

The statement offered no information on the method or possible motive in the killings, but said they were carried out “with cruelty and viciousness.”

Local and state politicians have increasingly become victims of violence that has cost over 13,500 lives since Mexico launched an offensive against drug cartels in late 2006.

Also Saturday in the northern state of Chihuahua, a severed human head was found placed on a car hood in the border city of Ciudad Juarez, along with a message relating to drug cartels, state prosecutors reported.

And Ciudad Juarez municipal police reported that one of their officers was shot to death outside his home late Friday.

The federal attorney general’s office reported Saturday that instructors of the U.S. Drug Enforcement Administration gave a course on drug addiction and prevention to federal and state prosecutors in Mexico. The course included instructions on organizing raids and other law enforcement activities, the office said in a statement.
