The decomposed body of a person was found near Venjaramoodu on Friday.
The deceased was identified as Sajeev of Karamana. Sajeev, who was employed at a scrap shop in Venjaramoodu, has been missing for the past three days, the police said.
The body, found in a plantain grove in Manickamangalam, was found to be in a severely decomposed state. Local residents reported a strong foul odour, which led farm workers in the area to search the nearby premises.
