On Monday, a journalist was shot dead in southern Mexico, shortly after posting online about the disappearance of 43 students eight years ago.
In 2014, 43 students from Guerrero went missing after their bus was commandeered.
Government investigation concluded that the students were handed over to the local Guerreros Unidos drug cartel and probably killed.
A few hours prior to his death, Fredid Roman posted online that a truth commission had accused top government figures of conspiring to conceal what had been done to the students.
Last week, the commission found the state responsible for the incident, after surviving students testified that Mexican police and military ambushed and opened fire on them.
Since the 2000s, approximately 150 journalists have been killed in Mexico, according to Reporters Without Borders.
