The night of 9 June 2006 was her 19th birthday. Both you and she were working as employees of Pizza Hut, although at different outlets. You collected her from the Cranbourne shop. You returned to, and finished your shift at, the Dandenong shop. Around 11.30 p.m., the two of you went back to the home of your parents. Just after midnight, there was an argument over a mobile phone of yours which she was using. After words were exchanged, you snatched at the mobile phone, and it broke. Each was left holding a piece. She went to her bedroom. She picked up her handbag. She said that she was leaving. She left the house. You went after her. On the footpath outside a nearby house, the two of you talked. You appeased her. The two of you walked back towards your home. She then said she wanted to make a report to the police that you had been harassing her. That led to further argument. Again she walked off along the footpath heading north.
Again you followed her. You came up behind her. You pulled on her and said: "Let's go home." She stood her ground and said: "You can't pull me." You then pushed her with both hands. That caused her to fall onto the concrete footpath. You heard a noise of her head hitting the footpath. You saw that she was shaking. You got no response when you talked to her. You left her and went to your home. You went back to her. Blood was coming out of her mouth. You chose not to call for help. Instead, you dragged her to the other side of the road. On that side there is a slope. You dragged her down the slope. The slope leads down to a body of still water. You took her close to the water. You left her there.
When the police spoke to you first later that morning, you chose to deceive them. In your final account later that day to the police, you were to say a number of things. Those things cannot, by independent evidence, be shown to be correct, or not to be correct. I am unable to be satisfied beyond reasonable doubt that there are incorrect. Accordingly I sentence you on the basis that they are correct. One of the things you said in your final account was that you initially laid Nileshni on her back about 2 feet from the water. Another was that you noted that she was not breathing from her mouth, but that her stomach or lungs were pumping up and down slowly.
You later went back to where you had pushed her causing her to fall. You took from that place her shoes and handbag, and put them next to her. You went home and cleaned up your shoes, which had got muddy. You took the cleaning of the shoes to be a priority. You told your mother that Nileshni had left the home following an argument with you. You said nothing to your mother as to the pushing, the fall, the dragging to the water, or Nileshni's compromised condition. You went out with your mother purporting to look for Nileshni. The body of Nileshni was then found. She was not close to, but face down in the water and substantially submerged.
Nileshni Singh died from upper airway obstruction in association with head injury. From the time you heard the noise of her head hitting the ground after you pushed her, it was obvious that she was in need of medical attention. You should have summoned such attention. You chose not to do so. That choice was grossly negligent. Instead of choosing to get help, you grossly increased the risk of causing an even more serious result. That was because, while aware of her being still unconscious, you dragged her to a position of great danger. You then continued to choose not to seek medical attention. Indeed, you aggravated the situation in how you deceived your mother as to what had happened. In my assessment, yours is a particularly serious case of manslaughter, although far from the top end of the scale.
