The body of a young Tamil man was found on Thursday in Eerakulam, Batticaloa, reported Battinews.
Nallathambi Vijikaran, 20, who hails from Siththandi, was reported missing by his family three days ago.
Mr Vijikaran, whose brother Nallathambi Nithiyananthan is a journalist, was staying at his family's house in Eerakulam when he went missing. His parents identified the body, which was found at Idakkaali riverside in the town.
As police failed to arrive in time to inspect the crime scene, the body had to be left at the riverside overnight and will only be removed on Friday.
