When she was on her way home in Pune from the IT company where she worked, Nayana Pujari was raped and murdered, allegedly by four men.
She was traveling in a car owned by her company. The driver and a security guard assigned to escort her home were arrested, along with two friends.
Ms Pujari was 27 when she was killed in 2009. Her husband, Abhijit, asked for a fast-tracked trial for his wife's case, but his petition was rejected by the Maharashtra Home department.
In September 2011, when he was brought to the Sassoon Hospital for a medical check-up, the cab driver, Yogesh Raut, escaped. He didn't have to try hard. He said he wanted to use the toilet. A policeman removed his handcuffs and he was allowed to wander away unsupervised.
The escape paralysed the case. Mr Raut has still not been caught. Police sources say that in narco-analysis tests conducted on him, he allegedly referred to having raped another girl.
