A father, fed up with the actions of his son, doused him with flammable liquid and then set him afire, said judicial agents.
The burn victim survived but is hospitalized with burns over 60 percent of his body, said agents. Both men have the last name of Vesco.
Agents said that the elder Vesco found his son, 38, using drugs, and that triggered the violent response. The older man is in his 70s.
The incident happened in San Isidro de El General late Wednesday night.
