Special Judge S Lal, who is retiring soon, will give his decision after a 15-month-long trial of dentist couple Rajesh and Nupur Talwar, both out on bail at present, on charges of murder and destruction of evidence in the killing of their 14-year-old daughter and servant on the intervening night of May 15-16, 2008 at their Jalvayu Vihar residence in Noida.

The probe followed a sine curve with varied theories from the investigating agencies--Uttar Pradesh Police and CBI--starting with father Rajesh Talwar being a suspect to the domestic servants of their friends and back to the dentist and his wife.
