Cepeda published the official figures on his Twitter account, at a time when frequent violent acts have been reported almost daily in the country.
He denounced the assassination of Benjamin Banguera, a signatory to the 2016 Peace Agreement between the Colombian State and the former Revolutionary Armed Forces of Colombia People's Army (FARC-EP) guerrillas.
We denounce the murder of the reinstated Benjamin Banguera Rosales in Guapi Cauca. He was killed with two shotgun wounds. We demand guarantees!
One of the latest violent acts was condemned by the Catatumbo Small Farmers' Association.
Social leader Tulio Sandoval, who was participating in the program to replace illegal crops was killed by armed individuals who broke into his house, dragged him out and shot him repeatedly in front of his family.
In this context, General Prosecutor Fernando Carrillo called recently to stop what he described as "the systematic assassination of social leaders."
All this more than three years after the signing of the Peace Agreement and 17 months since Ivan Duque took office as Colombia's president.
Since the peace accord, the United Nations' High Commissioner Office for Peace in Colombia has counted "303 assassinations of human rights leaders."
A total of 10,468 homicides have been officially recorded in Colombia between January and November 2019 according to the Foundation Peace and Reconciliation.
