Reacting to the Delhi High Court sentence of life imprisonment to Manu Sharma in the Jessica Lal [Images] murder case, Bina Ramani, key witness in the case, said on Wednesday that she cannot rejoice at somebody's sentencing.

"I can't rejoice at somebody being sentenced but it's true that karma of justice has been done," Ramani told reporters at her Goa [Images] residence.

Ramani said she cannot celebrate the sentencing as it has brought grief to someone's house.

"But it's been a long struggle and finally justice is delivered," she said in a short interaction with mediapersons.
