Mexico's National Human Rights Commission will present a report to the United Nations Monday on the country's "serious problem" with disappearances.

NBC News reported the Latin American country has no clear mechanism or national registry to calculate the number of people are missing. According to the latest official figures, over 23,000 people are missing in Mexico, while the country's Attorney General's office is investigating the disappearance of 621 people.

Mexico's National Human Rights Commission's goal is to ask the U.N. Committee on Enforced Disappearances to make recommendations to Mexico.

A group from the Inter-American Commission on Human Rights is meeting to further investigate the disappearance of the 43 missing students who were last seen in Guerrero state. The latest reports on the students say they were murdered by cartel members, but only one student's remains have been identified.

The attorney general and six of Mexico's 32 regions have started working on a unified database while searching for and identifying remains found in graves. The Human Rights Commission asked for Mexico to start that process and to make it a national, unified registry using a genetic registry.

The commission will also call on lawmakers to complete pending legislation related to the National Registry of the Missing Persons, according to The Associated Press.

Mexican President Enrique Pena Nieto's government promised it would release verifiable numbers on how many people went missing in Mexico and published a list of 22,322 people back in August, who have been missing since 2006.

Almost 10,000 people have disappeared since the beginning of president Nieto's administration two years ago.

Relatives of the missing 43 students from Guerrero state traveled to Geneva to talk to the United Nations committee about their experiences. The relatives continue to question the government on its allegations that drug cartels killed their children after being captured by police officials.
