Kerala police recovered the badly decomposed body of a 50-year-old man on Wednesday from his residence in Koluthur, according to media reports.
His wife, son and two daughters had been living with the corpse, which had been wrapped with cloth, for almost a month, said police.
Police entered the home after the man’s brother lodged a report when he had been missing for a month.
Police said the man’s neighbors were not aware of his death and that his son was the only person they saw coming and going in recent weeks.
The body was sent for postmortem examination and investigations are ongoing.
