The police in Telangana's Nalgonda have cracked the sensational murder case of a 48-year-old school principal and arrested two students who allegedly planned the crime for money and lavish spending. The victim, Kallu Roopa Reddy, the principal and director of Nagarjuna Public School in Kondamallepally, was found dead with 27 stab wounds at her residence in Kondamallepally on the morning of August 12. Her body was recovered when her husband, who was away in Hyderabad, informed neighbours that she was not responding to his phone calls. The neighbours alerted the police, who found her dead.
