Frustrated over her teenage son's prolonged ailment, a 45-year-old woman killed him by setting him on fire before immolating herself here today.
Police said Vijayalakshmi was upset as her 15-year-old son Manikandan had been suffering from tuberculosis and could not be cured despite hospitalisation and huge treatment cost.
She took the extreme step when her husband, a cook, had gone out for work.
