BENGALURU: A 55-year-old security guard confessed to murdering his 14-year-old nephew on Aug 4 over his incessant demands for money to buy a mobile game. He surrendered to police Thursday night after initially attempting to commit suicide.Cops recovered the teenager’s decomposed body from accused Naga Prasad’s rented room at Vinayaka Layout, Soladevanahalli, northwest Bengaluru.In his confessional statement, Prasad told police he slit his nephew Amogha Keerti’s throat with a knife after the argument over his demand for money for a mobile game.“Keerti was a short-tempered boy and would behave arrogantly with me. All these years, I was looking after him as he refused to live with his mother. But his demand for money, particularly for playing mobile games, was affecting me,” Prasad told police.After killing his nephew, Prasad locked his rented room from outside and tried to die by suicide by jumping into a nearby lake. However, he didn’t drown as there wasn’t enough water, police said. “He then went to KSRTC bus terminal in Majestic and spent time loitering on the platforms, eating at a hotel and sleeping on the benches. Finally, he decided to surrender Thursday night,” an investigating officer said.
