Then, he appeared in many flops like "Pesadha Kannum Pesume", "Enge Enadhu Kavithai" and "Unarchigal". Several of his other films had delayed releases or were shelved, like Rithik's "Kadhalithal Anandam", which would have featured him alongside Livingston and Kausalya. When he was unable to find roles as an actor, he served as assistant editor for several films and turned to producing. His last film was "Nanbanin Kadhali", which released in 2007. On 7 February 2008, Kunal was found hanging from the ceiling in his Mumbai apartment by actress Lavina Bhatia. The apparent suicide was challenged by his father Rajendra Singh who claimed that the body showed signs of suspicious bruising. Bhatia was detained by police in connection with his death, but she was later released after the police could not prove a motive. The police were unable to prove that anyone was present in Kunal's apartment at the time of his death and ruled out Bhatia as a suspect as Kunal had a black belt in karate; furthermore, Kunal had attempted suicide by slashing his wrists several months earlier. At the time of his death, Kunal was working on a Hindi film, "Yogi", which was being produced by his newly formed production company Balagiri. The case was referred to CBI and Prof T D Dogra of All India Institute of Medical Sciences. He examined the scene of crime along with CBI and opined in favor of suicide. Walker  Rob B. J. Walker (born 1947) is a Professor in the Department of Political Science at the University of Victoria, Canada, and PUC-Rio. He is the founding co-editor, with Didier Bigo, of the journal "International" Political Sociology, and long-term editor of the journal "". With his colleague Warren Magnusson, he is a founding member of UVIC's interdisciplinary Graduate Program in Cultural, Social and Political Thought. His work, while critical of International Relations and Political Theory disciplines, addresses a broad range of problematics bound up with practices and theories of spatiotemporality, boundaries, and sovereignties. Walker has written extensively on the logic of 'inside/outside,' a dichotomy which enables and frames International Relations and its theorizations. For Walker, border practices and boundary discourses, spatial demarcations and conceptualizations of here/there and us/them, operate as important sites for understanding these 'inside/outside' logics.
