(CN) - Former Mexican president Luis Echevarria will not face charges for genocide in connection with a student massacre in 1968, a Mexican court ruled.
The federal court upheld a lower court ruling that Echevarria, who was the interior secretary at the time, was not involved when soldiers shot students in a plaza, days before Mexico City hosted the Summer Olympics.
Reports vary as to whether dozens or hundreds of protesters died in the shootings.
The 87-year-old Echevarria, who led Mexico from 1970-76, also faced genocide charges in 2005 in connection with a 1971 massacre. However, the statute of limitations ran out in 1985.
