The governor of a Mexican state where two protesting college students died during a clash with police said Wednesday that 10 officers are being investigated in the case.
Guerrero state Gov. Angel Aguirre said five state police officers who helped clear the students from a highway they were blocking and five other officers who arrived at the scene with the state's deputy security secretary were under investigation.
Students from the Ayotzinapa teachers college were blocking a highway that leads to the Pacific coast resort of Acapulco when shots were fired Monday. They were demanding more funding for the school and assured jobs once they graduate.
Aguirre said investigators had not yet determined who shot the students.
A few hours after the governor's comments, federal prosecutors announced that they were taking charge of the investigation.
