The 4th additional sessions judge G. Venkata Krishnamraju also held an aide of the duo guilty for murder and handed him down the rigorous life term under various charges, including hatching a criminal conspiracy, of Indian Penal Code.
The court has imposed fine of Rs 500 on each of the three convicts.
The court examined 14 witnesses in the 2001 case in which accused Aruna (32), a resident of Bommareddypalli village in the district, hatched a conspiracy to murder her husband, Gaddam Ravinder Reddy (35) with the help of her lover Singireddy Sudhakar Reddy (34).
According to the prosecution, Singireddy with his friend Kyatam Pritviraj (20) axed Reddy to death while he was on his way to kothur village on May 18, 2001, and dumped his body into bushes at the spot.
Aruna later lodged a missing person's complaint with police.
