Urgent Action: Defender’s Body Found After 40 Days Missing (Mexico: UA 162.19)

November 22, 2019

Authorities found the body of Arnulfo Cerón Soriano, indigenous human rights defender, on 20 November in a clandestine grave near the city of Tlapa, Guerrero state in western Mexico. Arnulfo was a member of the Popular Mountain Front and Movement for the Freedom of Political Prisoners of the State of Guerrero (MOLPEG). He disappeared on 11 October on his way to a meeting in this city. Authorities must redouble their efforts to investigate his disappearance and death, holding those responsible to account, and ensure safety of Arnulfo´s family and organizations that support him.

Dear Governor,

I am shocked at the discovery of the dead body of Arnulfo Cerón Soriano. During 2019, Arnulfo and members of MOLPEG had received threatening phone calls and messages relating to their activism work. Following the arrest of suspects in Arnulfo´s disappearance, family members received threatening messages, MOLPEG members noted strange persons outside their residences and Tlachinollan Human Rights Center has observed unknown subjects staying watch outside their offices.

Yesterday, state authorities announced an investigation into the death, and continuation of the investigation into Arnulfo´s disappearance. These investigations must consider his work as a human rights defender in ensuring a robust enquiry.

I urge you to ensure state authorities carry out an effective investigation into the disappearance and death of Arnulfo Cerón and bring those responsible to account while guaranteeing the safety of MOLPEG members, family members of Arnulfo Cerón and staff of Tlachinollan Human Rights Center.

Yours sincerely,
