MUMBAI, Sept. 19 -- A childhood friend of murder victim Sheena Bora on Thursday told a special CBI court that Sheena had once expressed a desire to "take sanyas" (abandoning worldly pursuits) to escape the constant turmoil in her life and described her strained relationship with her mother and prime accused Indrani Mukerjea. Deposing as a prosecution witness, Sanjana Phukan Raktim - who studied with Sheena from nursery till Class X in Guwahati - produced email exchanges that, she said, revealed Sheena's family troubles, health issues, and alleged harassment by Indrani. Raktim is among 69 fresh witnesses added by the CBI this year and has been described by the agency as "important" because her correspondence with Sheena details the difficulties the latter allegedly faced at home and at work. One email dated August 26, 2009, read, "I want to take sanyas, only then I won't have to worry about work, renting home, or any other thing." In another, Sheena spoke of being hospitalised after being given "wrong medication" and wrote, "When I received your message, I was at the hospital and had no energy to reply back." According to Raktim, Sheena confided that she had stopped speaking to Indrani, saying her mother "cannot change" and she did not want to make her life difficult again. She also told her friend she was living with Rahul Mukerjea, son of media executive Peter Mukerjea from an earlier marriage, as her relations with Indrani had soured further. "She told me Indrani tried to get her out of her job through contacts and even stopped her salary. She (Sheena) tried hard and somehow managed to save her job," Raktim told the court. Raktim said she last met Sheena in 2011 in Guwahati during her own wedding....
