What happened with REPSA and the La Pasión river in 2015?

In Sayaxché, Petén (a mostly Q'eqchi' population), the palm oil producer REPSA (Grupo Olmeca) became associated with the mass fish kill on the La Pasión river from Jun 6,… 2015 (~160 km of river, at least 23 species, 12,000 people directly affected);… a criminal court suspended its operations on 17 September 2015 and the next day the complainant Rigoberto Lima Choc was murdered, while company workers briefly kidnapped 3 leaders. The case became the region's reference point for 'ecocide' and is the antecedent of social scrutiny of the palm chain.
