In another frightful reminder of the perils of the isolated life in cities, a daughter discovered her father's skeleton from his residence in Thiruvananthapuram on Sunday.

The body of KP Radhakrishnan, 70, was found in an almost fully decomposed state on a sofa in his two-storey house at the Old Medical College Road, according to a Times of India report.

Radhakrishnan, a retired tutor at a dental college in the city, had been living alone for the past few years after being separated from his wife. His daughter, who is a medical student and married to a doctor, lives with her mother in Kottayam.

According to the police, she would call her father occasionally and last spoke to him around four months ago. She decided to check on him on Sunday after reportedly finding his phone switched off for days.

She informed the Medical College police after finding unattended bills and envelopes on the doorstep. The police forced the door open and found the decomposed body in the drawing room.

The police suspect that the body is several weeks old and have registered a case of unnatural death. The neighbours said Radhakrishnan led a secluded life and barely spoke to anyone. The body has been released to relatives after inquest and post-mortem.

In two similar incident reported in August, a college student from Kasaragod, who was staying in a hostel, came home after a week to find the decomposed body of his mother, while an IT professional returned from the US to Mumbai to find his mother's skeletal remains.
