A council worker found Gurshan's body in grass in Melbourne's north on the evening of Thursday, March 4, six hours after he was reported missing.

Speaking on SBS Radio's Punjabi program yesterday, his mother Harpreet Kaur Channa said she was horrified by her boy's death.

''How could the perpetrator not think that he was making such a small child the victim of such a big crime? How could he inflict such a painful death to my child? How would my child have borne that terrible death?'' she said.

''May God punish the person who perpetrated such a heinous crime.'' Mrs Channa sobbed as she described the last time she heard her boy.

''When I went into the shower, he was knocking on the door. Maybe he wanted to say, 'Mum don't go','' she said.

She said she wanted Australians to pray for her to have another baby.

''Our families are supporting us. They keep saying that we'll have another baby soon,'' she said.

''Please pray for me, that I have another child so Gurshan comes back.''

Mrs Channa said her son was a happy boy who was developing quickly and loved Melbourne, even though he was scheduled to leave Australia for India with his parents the weekend after he disappeared.

''He had called his grandmother [in India], just a few hours before he went missing that day,'' she said.

Gursewak Dhillon, 23, has been charged with manslaughter by criminal negligence. He appeared briefly in the Melbourne Magistrates' Court on Tuesday and has been remanded in custody to reappear on June 29. AAP
