The investigating team came to know about this when they were scrutinizing Indrani's laptop in connection with the case. INX co founder Indrani had sent series of hate mails to Sheena and her brother Mikhail from her gmail account.
These emails were sent a month before Sheena was murdered. Total three mails were sent from Indrani gmail account.
According to TOI, in one of mail which was addressed to Sheena and forwared to Mikhail, Indrani had threatened to disinherit both Sheena and Mikhail if they "acted smart".
She also said that if they (brother and sister) will not toe her line, she will stop monthly payouts of Rs 40,000 each.
Surprisingly, one of the mail was sent before the murder on March 8, 2012 while others two were sent after murder on May 4 and July 7, 2012.
Police have yet not understood why Indrani sent two mails after Sheena was murdered on April 24, 2012. Apparently Indrani's motive was to misguide the investigating team.
Reportedly, Mikhail didn't reply back, fearing Indrani might stop his monthly pocket money of Rs 40, 000. But Sheena replied Indrani back saying that she will expose her in front of her present husband Peter Mukherjea.
It is yet not clear what was the exact matter on the basis of which Sheena was threatening to expose Indrani. Quoting a source TOI writes, "Now what she wanted to expose we don't know. We are assuming that Sheena may have been threatening to tell Peter the truth that Sheena and Mikhail were Indrani's children and her not brother and sister as she told Peter".
Sheena had gone missing in 2012. Indrani Mukerjea, her former husband Sanjeev Khanna and driver Shyam Rai allegedly had killed Sheena and later disposed of her body in a jungle in Raigad, near Mumbai.
All three accused are in the judicial custody at the moment. Sheena was in a relationship with Peter's son Rahul from his previous marriage.
