Indrani Mukerjea ensured her daughter Sheena Bora and her son Mikhail did not communicate with each other on the day of the alleged murder.
According to the police, Indrani had called Mikhail to Mumbai from Guwahati, where he lives, on April 24, 2012, the day Sheena was murdered.
Police sources said Indrani had meticulously planned to kill Sheena and Mikhail, but her son escaped.
Sheena was not aware of Mikhail’s presence in the city, sources said, adding he was allegedly asked to come to Mumbai by Indrani on the pretext of discussing a property matter.
The police said Mikhail did not inform anyone of his presence in the city. Police sources said Sheena and Mikhail were in touch with each other even after Sheena moved to the city and it was surprising that he did not contact her.

After news of Sheena’s murder broke, Mikhail claimed Indrani had been paying him to keep quiet about his exact relationship with Indrani.
Mikhail has shared the email exchanges he had with Sheena, in which she has told her about the issues she had with Indrani, said police sources.
Sources said from the investigations they got a sense that Indrani was aware she would not be able to execute the murder alone for which she roped in her driver Shyamvar Rai and former husband Sanjeev Khanna.
She manipulated everyone and also ensured that her husband Peter and daughter Vidhie were away in the UK when she executed her plans to murder Sheena.
Mikhail had earlier told police officers he did not feel well after consuming a drink given to him by Indrani and claimed it was spiked.
He had said he somehow managed to get out of the Worli flat. But it is still not clear where Mikhail went from there.
The police arrested Indrani last Tuesday for the murder of her daughter Sheena Bora on April 24, 2012. The police first arrested Rai after getting a tip-off about the murder.
During interrogation, Rai admitted to his role in the murder and led the police to Indrani and eventually Khanna.
