In the absence of hard evidence, crime branch is relying on the statement of the deceased’s cook and web search history and purchase orders for arsenic and thallium. All this proves Kavita alias Kajal Shah and her paramour Hitesh Jain poisoned her mother-in-law, too. Kajal and Jain then murdered the former’s husband, Kamalkant Shah, the same way, the cops said. Both Kamalkant and his mother Sarla Devi Shah died barely a month apart, last year.

Search history

According to Unit 09 of the crime branch, Jain's web search history shows that he had been procuring arsenic and thallium from different dealers since July 2022. He also looked up arsenic 105 times and thallium 156. He was in contact with the dealers via WhatsApp on July 20 to procure the poison, and hence it clearly confirms that the duo poisoned Sarla Devi because she died in August, said the cops.
