A HIDDEN grave on the outskirts of a Mexican city where police clashed with student protesters a week ago contained 28 bodies, but the remains are too damaged for immediate identification.
Guerrero State Prosecutor Inaky Blanco said he could not say whether any of the dead could be some of the 43 college students reported missing after the violent confrontation in Iguala, 120 miles south of Mexico City.
He said genetic testing of the remains could take two weeks.
Blanco said one of the people detained in the case had told investigators that 17 students were taken to the grave site on the outskirts of the Iguala and killed there. But he stressed that investigators had not confirmed the person's story.
"As long as the identity of the cadavers has not been resolved we will continue the search for the missing students," he said.
State prosecutors have been investigating the Iguala city police for misconduct during a series of violent incidents last weekend that resulted in six shooting deaths and more than two dozen people injured. Investigators said video showed police taking away an undetermined number of student protesters.
Authorities have presented charges against 29 people in the case, including 22 police officers. Three of the suspects are fugitives, including Iguala's police chief.
Blanco said they are still investigating the motive for the crime, adding that some of the police have connections to a local drug cartel.
