Woman was on the phone to husband when stranger stabbed her to death

A reward of $1 million to help solve the 2015 murder of Prabha Arun Kumar in Sydney has been announced today by the New South Wales government.

IT worker Prabha Kumar, aged 41, was fatally stabbed on Saturday, March 7, 2015, while she was walking through Parramatta Park in the city’s west while talking on the phone to her husband.

She has just caught a train to Parramatta Railway Station on her way home from work in Rhodes at about 9.30pm.

Walking across a dimly-lit Parramatta Park, Kumar was 400 metres from her Westmead home when she was stabbed in the neck.

Emergency services attended the scene but were unable to save her and she died from her injuries.

A crime scene was set up and detectives began to investigate the killing.

Police have pursued multiple lines of inquiries and made several public appeals for information, but the case remains unsolved.

Now a $1 million reward has been announced for information that leads to the arrest and conviction of the person or persons responsible for the murder.

Police will provide an update later today.

Anyone with information should contact Crime Stoppers on 1800 333 000.
