Aaftab Poonawala had used a stone grinder on the bones of live-in partner Shraddha Walkar and disposed of the powder. Her head was one of the last pieces, which he threw away after three months, the Delhi Police have claimed. The 6,600-page chargesheet of Delhi's notorious fridge murder lists a series of gruesome details. Among other things, it also mentions that on May 18, after killing Shraddha, Poonawala had dined on a chicken roll brought from Zomato.
