The police recovered the decomposed body of the youth near Dhalavaipuram on Friday.
According to police sources, Marimuthu, who was working in SIPCOT industrial estate in Gummidipoondi, had befriended a woman in Tirunelveli through social media.
He had lent her Rs. 5 lakh. When he insisted her to return the money for his marriage, she had reportedly asked him to come to Tirunelveli to collect it.
