The Colombian Defense Minister, Luis Carlos Villegas [es], stated that the crash was most likely caused by bad weather.
[1][2] The flight was part of an operation against Clan Úsuga, a criminal organization composed of former right-wing paramilitary group members.
Two other helicopters flew on the same mission but did not encounter difficulties and did not hear any hostile fire.
The spate of casualties have led to questions about the efficacy of the military's air operations procedures.
[4] A debate was organized in the Congress of Colombia to discuss the accidents, and the Defense Minister and Air Force Commander were called upon to testify.
