Colombian authorities uncovered a mass grave in the violent southern region of Guaviare this week, revealing the bodies of eight missing Evangelical Christian leaders.

The victims, who had vanished in April while conducting humanitarian work, were ultimately located after an investigation linked to FARC dissidents led by a commander known as Iván Mordisco, marking Colombia’s most significant massacre of 2025 so far, The Christian Post reported.

The grave was discovered on Tuesday in a rural zone of Calamar, Guaviare, a region heavily affected by ongoing armed conflict. The victims had all disappeared earlier this year while providing both spiritual guidance and charitable services. All were originally from the department of Arauca in eastern Colombia.

Identities of Victims and Affiliated Faith Groups

The deceased were identified as James Caicedo, Óscar García, Máryuri Hernández, Maribel Silva, Isaid Gómez, Carlos Valero, Nixon Peñaloza, and Jesús Valero. They were affiliated with the Evangelical networks Alianza de Colombia and Cuadrangular, both of which are dedicated to spiritual leadership and social outreach in remote regions of the country.

Authorities say the group was lured in April by members of the Armando Ríos Front, a dissident faction comprising former members of the Revolutionary Armed Forces of Colombia, or FARC. The summons is believed to have come under direct instruction from Iván Mordisco, a prominent leader defying Colombia’s peace accords.

According to investigations by the prosecutor’s office, the victims were allegedly killed to prevent the growth of a cell affiliated with the National Liberation Army (ELN), another militant faction. However, no explicit connection was uncovered between the murdered leaders and any paramilitary group.

Breakthrough in Investigation Came from Digital Evidence

The discovery of the grave was made possible through the arrest of a guerrilla fighter in May, which yielded critical digital evidence. Authorities found images stored on the individual’s phone that depicted the detained victims and photographs of the site where the killings occurred.

This evidence led officers to the exact location of the makeshift burial ground in Calamar. Indepaz, an independent peace and conflict think tank, announced this to be the most severe massacre in Colombia in 2025 so far, amid a spike in rural violence.

According to Indepaz, over 30 mass killings have already been recorded in rural parts of the country this year, particularly in regions contested by FARC and ELN dissident groups. Guaviare, in particular, has suffered increased instability due to clashes involving Mordisco and another dissident leader, alias Calarcá.

National and International Reactions to the Tragedy

President Gustavo Petro publicly condemned the killings, labeling them a grave breach of human rights. He emphasized the urgent necessity for a stronger governmental presence to safeguard civilians and social leaders operating in conflict zones.

The daughter of one of the victims spoke to local outlet SEMANA, conveying a desperate appeal for help. She said the civilian population was caught between rival armed groups and felt completely unprotected, adding, “Here we are really alone in a war between two armed groups.”

The Evangelical Confederation of Colombia (CEDECOL) also issued a strong statement alongside its condolences, highlighting the need for swift justice and greater security for faith-based organizations. It stated that spiritual workers in vulnerable regions must be guaranteed safety and dignity amid growing violence.

Calls for Change and Broader Security Measures

CEDECOL quoted from a biblical passage—“Blessed are those who suffer persecution for righteousness’ sake”—and urged the authorities to prevent future violence against spiritual leaders. It declared continued commitment to defending life, honesty, fairness, and peace in Colombia.

Outside of religious circles, international organizations also weighed in. The representative from the United Nations Human Rights Office warned that attacks like this contribute to silencing essential community voices and worsen humanitarian conditions across remote territories.

The mayor of Calamar also voiced concern, telling the newspaper El País that local residents feel abandoned by the national leadership. He called for immediate intervention to stabilize the region, emphasizing that even elected officials face intimidation from illegal groups.

Guaviare’s Worsening Security Climate

Earlier this year, the town of Calamar had already seen devastating violence. In January, at least 20 bodies were received at the municipal morgue after clashes between illegal factions, highlighting the ongoing crisis that predates this most recent massacre.

Guaviare remains one of the regions hardest hit by Colombia’s post-conflict challenges, as dissident groups reject the 2016 peace agreement and attempt to exert control over rural corridors. Control of these areas is vital for illegal economies, including narcotics and illicit mining.

Residents, social leaders, and relief workers continue to operate under threat, with limited support from state institutions. The latest killings have sparked new national debate over how to protect vulnerable communities caught in territorial disputes.
