A mother of two, who has been having an affair with another man, added poison to a packet of fried rice that she served to her husband,
Amsa, 35, and her lover Tirupathy managed to kill Ramesh, 45, Tamil Nesan reported.
However, Ramesh's nephew Sampath suspected something amiss and lodged a police report in Tirupattur, about 100km from Chennai. Sampath said his uncle was a healthy man, but he died suddenly on June 16.
Following the complaint, police launched an inquiry and exhumed Ramesh's body.
Under interrogation, Amsa confessed. She said Ramesh fell unconscious after eating the rice.
Tirupathy and Amsa then took him back to their village, where Amsa told villagers that her husband was suffering from an upset stomach. He died at their home later.
