More mass graves discovered in Mexico missing students case

Mexican Attorney General Jesus Murillo Karam on Thursday announced the discovery of four new graves outside Iguala, where the violent events occurred, with the help of the testimony of four jailed suspects.

Murillo made the announcement just after President Enrique Peña Nieto urged his security Cabinet to speed up the investigation into what occurred in Iguala and determine who was responsible.

Earlier this week, thousands of Mexicans took to the streets around the country to demand authorities find the 43 missing teacher trainees and ensure justice prevails.

On the night of Sept. 26, municipal police in Iguala opened fire on dozens of students who had commandeered several buses to return home after a fundraising drive, part of a night of violence in which six people were shot dead and 25 others were wounded.

Witnesses said the police also shoved numerous teacher trainees into patrol cars and they have not been seen since.

After five clandestine graves containing 28 bodies were discovered last weekend, the federal government took over the investigation and sent in federal forces to assume security duties in Iguala.

The authorities have arrested 30 people suspected of involvement in the events, including 22 municipal police allegedly linked to a local criminal gang.

Several of the suspects have confessed to burying the students after they were killed.

Murillo said the bodies have yet to be identified as those of the missing students.

Meanwhile, federal agents are trying to locate the mayor of Iguala, Jose Luis Abarca; his wife, Maria de los Angeles Pineda; and the Iguala police chief Felipe Flores, for questioning about their involvement in the events.

Mexican Foreign Relations Secretary Jose Antonio Meade on Thursday pledged to provide regular updates on the investigation into the missing students.
