The SSP said Fiza's advocate-friend Ranjeet Hooda had also told the SIT that she was under depression. "Though the medical report is not the last evidence, we rule out any foul play in her death as of now," he said.
The highly decomposed body of 39-year-old Fiza was found at her Mohali residence on August 6.
Fiza had shot into limelight four years ago following her controversial marriage to Chander Mohan, son of former Haryana CM Bhajan Lal.
