The mystery behind the collapse of Indrani Mukerjea, arrested for the murder of her daughter Sheena Bora, at the Byculla prison on Friday deepened further after a report by the Maharashtra Forensic Science Laboratory ruled out an overdose of any medicine.
So far it was suspected that she had taken an overdose of anti-depressants and anti-epileptic pills that she was taking for a few days at the Byculla prison where she has been lodged since September 7.
An official from the FSL said that they ran tests on her stomach wash, blood and urine samples and did not find any chemicals to suggest a drug overdose. "It may be some health problem or ailment she may be suffering. The doctors at JJ will be able to determine that better," said an official from FSL requesting anonymity.
