"Annamma soon began doubting Jolly's educational status and fearing that she would spill the truth, Jolly murdered her. She used a dog poison called 'Dog Kill' and mixed it with Annamma's mutton soup to kill her," KG Simon, who heads the SIT, told local media on Monday. While her first alleged attempt at poisoning Annamma failed as the quantity of dog poison she added was less, Jolly allegedly mixed the poison in the 57-year-old's soup again on August 22, 2002, murdering her.
