The mystery behind the missing bullet-proof jacket of slain Maharashtra Anti-Terrorism Squad chief Hemant Karkare took a new turn on Wednesday with a sweeper of a government hospital in Mumbai claiming that he had disposed it off long ago. The statement evoked a sharp reaction from Kavita Karkare, wife of the slain officer, who said, "This theory had cropped up now because the government is under pressure. I have lost all hope of getting fair justice in this case."
