Kajal Shah, accused of killing her husband Kamalkant Shah by slow poisoning him with Arsenic and Thallium, allegedly consumed the poisonous chemicals for a few days to avoid raising suspicion. Unit 9 of Mumbai police’s Crime Branch made the statement before the Killa Court on Thursday while seeking extension of the custody of the accused.

According to the police, Shah’s report had come on September 13 showing high levels of Arsenic and Thallium. Following this, the doctors had asked all of his family members to undergo heavy metal blood tests. The Santacruz-based businessman’s kids and sisters went through the test and their reports were normal. Kajal, however, got tested on September 23, four days after Shah died and the doctors had confirmed it was a case of poisoning.
