Nitin P Singh will have to serve 85 per cent of the sentence before being eligible for parole under the terms of the sentence handed down by the apex court judge Linda Lawhun in Salem, New Jersey.
The accused killed his 42-year-old wife Seema Singh, who was a Collingswood shopkeeper, in July last year in their own apartment while their three children slept nearby. The children were not injured, according to NJ.com.
The accused attacked his wife after she said she was leaving him and would be taking all of his money and their children with her, according to a statement registered by the Indian-origin man himself.
He said that he went into a rage and picked up the first thing he saw, a knife, and began stabbing her. Nitin then called 911 to say his wife was not breathing. He was later charged with murdering her by stabbing her nearly 40 times.
