The body of a Tamil woman was found on Friday at Trincomalee beach.
The 29-year-old woman, Pothanayagi Nadaraja, was a lecturer at the Trincomalee campus of Eastern University, and is originally from Vavuniya.
Identifying her body, her husband told journalists that they had got married recently and were expecting their first child.
"She did not commit suicide," he said. "This is murder."
Trincomalee police are investigating the incident.
