Jury retire at husband's fire murder trial

A jury has begun deliberating at the trial of a Sydney man accused of murdering his wife by setting her on fire.

Kulwinder Singh, 41, has pleaded not guilty in the NSW Supreme Court to murdering Parwinder Kaur, 32, on December 2, 2013, at their Rouse Hill home.

Ms Kaur, who sustained burns to 90 per cent of her body in the petrol-fuelled blaze, was seen by neighbours on fire, slowing moving down the driveway with her husband behind her.

The Crown alleges Singh was responsible for her death, while he told police "she did it to herself" when he was upstairs in their bedroom before he rushed down after hearing her scream.

His lawyer submitted the "tragic accident" occurred when Ms Kaur was seeking some sort of attention.

After a two-month trial before Justice Natalie Adams, the jury retired on Monday.
