According to the CBI, Indrani and the other two strangled her daughter Sheena (24) inside a car on April 24, 2012, and then disposed of the body in a forest in Raigad district.
"I came to know (about the case) and remembered the visit of three persons (two male and a female) at the place," claimed Raigad-based Sandeep Patil, whose statement is a part of the chargesheet filed by the central agency.
He then approached the suburban Khar police (who were probing the case at that point) and informed them, he says, adding that he identified Indrani, Khanna and Rai in jail during an identification parade.
However, defence lawyer Shreyansh Mithare questioned the delay. "What took him so long to report it to the police? Why is there a gap of three years?" he asked, commenting on the statement.
