In 2010, a Tumkur court sentenced her to death for the murder of Muniyamma, in Yediyur Siddalingeshwara temple in Kunigal taluk and on Mar 30, 2012 she was again given a death sentence for the murder of a housewife Nagaveni in Doddaballapur on December 18, 2007.
The housewife was found dead in the premises of a temple in Doddaballapur. She was a resident of Allalasandra, near Yelahanka New Town.
Malllika had befriended Nagaveni, who was childless. The victim visited various temples to pray for a child.
She told the would-be mother that she would perform a special puja to help her realize her desire.
She led her victim to a temple in Doddaballapur that morning, and pretending to give her holy water, instead provided water laced with cyanide. Nagaveni drank it and died instantly.
Later, the killer removed the victim's gold ornaments and escaped.
She was awarded death penalty in 2010, which was later reduced to life imprisonment in August 2012.
