On 25 October, land rights defender Noel Castillo Aguilar was killed in the community of Barra de la Cruz in the municipality of Santiago Astata, Oaxaca. Noel Castillo Aguilar is the fifth member of the organisation CODEDI to be killed in 2018.

Noel Castillo Aguilar was going home in a taxi on 25 October 2018 when he was attacked by unknown men with fire arms, who hit him on the head. He died around 1 p.m. that day. His father and human rights defender Leodegario Castillo Zarate had recently received death threats asking him to stop his work as an environmental human rights defender.

On 29 October 2018, a military convoy of marines traveled to CODEDI’s training center with no apparent reason other than to intimidate members of CODEDI, who were protesting the killing of the five human rights defenders.

Members of CODEDI have been subject to several attacks in 2018, including the killing of Alejandro Antonio Díaz Cruz, Ignacio Basilio Ventura Martínez and Ángel Martínez in February; Abraham Hernández González in July and Noel Castillo Aguilar in October. Three members of CODEDI were arbitrary detained on different dates between June and August of 2018 and the houses of three women human rights defenders were raided and robbed between February and October this year. Despite formal complaints to local authorities and constant public denunciations, investigations are not progressing and the precautionary measures issued by the National Commission for Human Rights (Comisión Nacional de Derechos Humanos, CNDH) have not been complied with.
