Kolkata: His diary entries did carry sexual overtones, but police on Monday said they have not found any evidence suggesting that Partha De, who lived with his sister Debjani's corpse for months, had an incestuous relationship. A search also yielded notes by Debjani suggesting she starved to death in her bid to 'attain god'.

Meanwhile, the state-run hospital treating 44-year-old Partha said it was thinking of approaching the Missionaries of Charity for help, as the patient has repeatedly been pleading that he be allowed to interact with them.
