Mexico City, October 28 (RHC-NNN) -– Police searching for missing students have found more human remains in a new area of southern Guerrero state in Mexico. Authorities said it would take several weeks before the remains can be identified.

A police spokesman said that authorities came upon the new location based on statements from four people arrested early Monday. The new remains were found in Cocula, a town about 10 miles from where the students were last seen.

Meanwhile, Attorney General Jesus Murillo Karam confirmed four arrests. He said some of them could be members of the Guerreros Unidos cartel which is believed responsible for abducting the students after an attack by local police.

Two of the detainees said they received a large group of people around September 26th -- the date the students went missing, Murillo Karam said. Investigators were trying to confirm their statements.

Mexican police are said to now have a total of 56 people in custody in the case.
