Ramkumar had allegedly hacked Swathi to death at the Nungambakkam Railway Station in June this year. He is said to have attacked her with a sickle.

An engineering college dropout, Ramkumar had reportedly killed Swathi, a techie employed with Infosys, for rejecting his advances. The police zeroed in on him after getting footage of him from a CCTV installed at a house near the railway station.

He was arrested on July 2, and allegedly attempted suicide by slashing his throat when the police caught him. He was saved and admitted to a hospital in Tirunelveli for a while.

However, members of Ramkumar's family suspect foul play in his death.
