Public prosecutor R.K. Saini said the case comes under the “rarest of rare” category.
Counsel for the Talwars sought leniency from the court. Special CBI Judge Shyam Lal reserved the verdict for 3.30 p.m.
The Talwars were Monday held guilty of murdering their 14-year-old daughter Aarushi and domestic help Hemraj, 45 and from Nepal.
Both were found dead with their throats slit at the Talwar residence in Noida in May 2008.
The Talwars were in the court during the arguments on the quantum of their sentence. They insist that they are innocent. IANS
