Just read on how she executed her plans.

Mallika knew that Elizabeth (52), a Christian woman would not accept teertha (holy water offered in temples). Mallika took her to Kabbalamma temple in Sathnur cajoling her to conduct ‘Mandal Pooja’ saying that her missing son would return home. She requested Elizabeth to hold her nostrils with her fingers and offer prayers. When Elizabeth was about to follow the directions, Mallika intervened saying the procedure was wrong and she would show how to hold the nostrils. Mallika tightly held the victim’s nostrils which forced her to open her mouth. Immediately Mallika thrust cyanide into Elizabeth’s mouth and strangulated.

“Common sense tells you that a person will open mouth if his/her nose is closed,” she reportedly told the police. She would tell the victims to wear gold ornaments, while conducting the Mandal Pooja as the devotees should look like Goddess Lakshmi. If you don’t wear ornaments and don’t look like  Goddess, then the pooja won’t yield results,” she told the victims.

She would take the rooms in choultries attached to temples for three to four days and would commit the murder on the first day and vanish. This she did to mislead the police as the bodies would be decomposed after two to three days.

Mallika, the 840!
Pillamma (60), another victim, was a cheat. She, like Mallika, used to claim that she would end the problems of women by conducting poojas in a temple in Hebbal. Both became friends. Mallika won Pillamma’s confidence claiming that she had been possessed by many goddesses. She suggested Pillamma to construct a ‘gopura’ for a temple and also offered financial assistance. Mallika thrust cyanide into Pillamma’s mouth and killed her in Maddur on October 17, 2007. “It’s not a big deal to find out where the cyanide is available. Everyone knows those who are into gold polishing vocation use it. But, I learnt the effects of consuming the cyanide by watching the movies,” Mallika is said to have told the police.

Madivala link
Chandramma (35), a resident of Madivala and a worker in a garment factory, in whose house Mallika was serving as a maid in 2005, went outside along with Mallika. But, Chandramma didn’t return. Mallika cooked up some story when Chandramma’s daughter Vijaya asked why her mother didn’t return. Vijaya approached the police, but Mallika consumed some powder and fell unconscious. The police rushed her to a hospital and never bothered to revisit the hospital. They registered a missing complaint about Chandramma and kept quite. Now, the Kalasipalya police are trying to ascertain if Mallika killed Chandramma too.

Jailed in 2001
The Bidadi police arrested her in 2001 on charges of house theft in broad daylight. The court convicted her in the case and she underwent imprisonment for 168 days. When Mallika told them that only the devotee should be present and she should wear gold ornaments while conducting the pooja, the family members of the woman grew suspicious. They immediately alerted the police. When grilled, she said she wanted to commit theft, but never disclosed her intention of committing a murder.

Mallika arrested
Eventually, Mallika landed in the Kalasipalya police net when police inspector S K Umesh decided to investigate after reading about the deaths of Nagaveni (in Ghatisubramanya) and Pillamma. When Umesh collected call details of Yashodamma, he found a person had called Yashodamma’s number several times from a cellpone. He concluded on December 23 that it was the same woman who had been committing murders. Based on the number, police zeroed in on Mallika.
