NEW YORK (Reuters) - A man faces life in prison at his sentencing on Wednesday for the grisly murder of an 8-year old boy who got lost on his first walk home alone from camp in their close-knit Orthodox Jewish neighborhood in Brooklyn.

Levi Aron, 36, pleaded guilty on August 9 to second-degree murder and kidnapping in the death of Leiby Kletzky. The boy went missing on July 11 last year and his body was found two days later.

Prosecutors said they will seek a sentence of between 40 years and life in prison when he is sentenced in Brooklyn state court on Wednesday afternoon.

Aron kidnapped Kletzky after he sought the man's help on the street when he lost his way walking home after religious camp, prosecutors said.

Instead, Aron led the boy to his apartment and the child's disappearance triggered a massive search by the community and police.

After seeing missing child flyers plastered throughout the neighborhood, Aron said that he "panicked," and drugged the boy with prescription medication and suffocated him with a towel, according to court documents. Aron admitted that he then dismembered the body, disposing of the parts in a dumpster and his freezer, where police later found them.
