There's a pall of gloom and fear at the home of Murugan, a Dalit science graduate residing in the Pudukottai village in Tuticorin district. A 17-year-old girl from the upper caste Thevar community, who had eloped with him, was found murdered a few days ago in the neighbouring Tirunelveli district. The police suspects the family of the girl to be behind the murder and has arrested her two brothers.
