Mexican police found 10 decapitated bodies and 11 heads Wednesday near the same location where 43 students went missing last year.

Many of the bodies were found just 30 miles from the Guerrero state capital with their hands tied behind their backs, Reuters reports. Officials said the bodies showed signs of torture. They also found 11 heads in one grave placed in four separate plastic bags. The identities of the victims have not been confirmed as of yet.

The mass grave was found while the Mexican government is still investigating the case of the 43 missing students who were last seen being rounded up by police on Sept. 26, 2014.

Attorney General Jesus Murillo said the police may have handed the students over to drug cartel members based on current evidence. Since the investigation, only one student's remains were found.

Regarding the case of the missing students, people have protested in the streets of Mexico for months demanding the truth. Mexican President Enrique Pena Nieto issued a program to end drug violence in the country as a result.

President Barack Obama said he is committed to helping Mexico get rid of the drug cartels but that it is up to the Mexican government to resolve the issue.

Back in October, the Mexican government found 28 bodies in nine mass graves that did not belong to any of the students, The Guardian reported.

Hundreds of teachers, students and relatives continued to protest to find the students. At times, protests became violent as demonstrators smashed the windows of an office building and set things on fire.

Over 10 officers have confessed to being involved with the disappearance. After months of different stories, the final word was that all students were incinerated and thrown into a river by drug cartel members.
