The Crime Branch, which is investigating the murder of Santacruz businessman Kamalkant Shah, may register another case of murder against the accused Kajal, and her paramour Hitesh Jain for allegedly killing Shah’s mother using the same method. Shah was poisoned to death, the police have said. Crime Branch sources said Kajal and Jain confessed to killing Shah’s mother Sarla Devi, 65, by slowly poisoning her.

While Sarla Devi died on August 13, a month before Shah’s death, the hospital declared it a natural death as no one from her family raised an alarm. The doctors also didn’t suspect anything wrong considering that she was an elderly person.
