  After the peace agreement of 2016 with FARC, the killings of social leaders
have emerged as an important post-conflict challenge for Colombia. We present a
data analysis based on official records obtained from the Colombian General
Attorney's Office spanning the time period from 2012 to 2017. The results of
the analysis show a drastic increase in the officially recorded number of
killings of democratically elected leaders of community organizations, in
particular those belonging to Juntas de Acci\'on Comunal [Community Action
Boards]. These are important entities that have been part of the Colombian
democratic apparatus since 1958, and enable communities to advocate for their
needs. We also describe how the data analysis guided a journalistic
investigation that was motivated by the Colombian government's denial of the
systematic nature of social leaders killings.
