Soldiers found six clandestine graves in a forested area in the western Mexican state of Michoacan that contain burned human remains, the army said Tuesday.

Information obtained from two gunmen led army troops to the burial site Monday outside Tuxpan, a city in eastern Michoacan, the 21st Military Zone in Morelia, the state capital, said.

The shallow graves, which are between 30 centimeters and 50 centimeters (about one foot and 20 inches) deep, contained charred bodies, a Michoacan Attorney General's Office spokesman told Efe.

A wood-burning incinerator was found nearby, the AG's office spokesman said.

The bones found at the site were no larger than 20 centimeters (eight inches) and were sent to the coroner's office, where doctors will extract DNA and perform tests to determine how many people were buried in the graves, the AG's office spokesman said.

Two suspected gunmen, identified as Juan Carlos Rodriguez and Jose Manuel Valencia, were arrested in the city of Irimbo last Thursday and provided investigators with information about the burial site.

The suspects had a training manual from a drug cartel and cell phones that contained photos of dismembered and burned bodies in their possession.

The government deployed about 1,000 Federal Police officers in Michoacan last week to deal with a wave of drug-related violence.

The violence in the western state is being blamed on the Los Caballeros Templarios cartel, which was founded in March 2011 by former members of the La Familia Michoacana organization and now controls drug trafficking in Michoacan.

The cartel controls the traffic in both synthetic drugs and natural drugs in the western state.

The Federal Police's mission is to arrest Caballeros Templarios leaders Dionisio Loya Plancarte, Enrique Plancarte Solis and Servando Gomez Martinez.

The three suspects are believed to be hiding in the mountains around the city of Apatzingan.

Michoacan has 270 kilometers (168 miles) of Pacific coastline, making it an ideal location for drug traffickers smuggling narcotics from South America into the United States.

The drugs are then moved via the Pacific corridor or through central Mexico into the United States, the world's largest consumer of illegal drugs.

Mexico registered 27,199 murders in 2011, the highest number since President Felipe Calderon took office in December 2006, the National Institute of Statistics and Geography, or INEGI, said Monday.

More than 50,000 people, according to official figures, have died in drug-related violence in Mexico since late 2006.

The Movement for Peace with Justice and Dignity, which was founded by human rights activist and poet Javier Sicilia, puts the death toll from Mexico's drug war at 70,000. EFE
