Judge MiguelVazquez said charges were warranted 39 years after the killing because the court had evidence that former officers Pedro Barrientos and Hugo Sanchez carried out the killing.
On 28 December, Judge MiguelVazquez accused Mr Barrientos, a former lieutenant, and Hugo Sanchez Marmonti, an ex-colonel, of homicide, while the other six were accused of complicity to commit murder.
