A 40-year-old man was sentenced Friday to 50 years in New Jersey state prison for the 2016 fatal stabbing of the 37-year-old Burlington County mother of his child, prosecutors said.

Rashon A. Causey, of Burlington City, was found guilty by a jury in October of killing Shanai Marshall in her Mount Holly home on Nov. 14, 2016.

He must serve more than 42 years of his sentence to become eligible for parole.

Assistant Burlington County Prosecutor Courtney J. O'Brien argued for life in prison, pointing out that Causey had an extensive criminal record as a juvenile and an adult: 92 arrests and 11 felony convictions.

More than 20 of the victim's family members and friends attended the sentencing, including two who addressed the court about the magnitude of their loss, prosecutors said in a statement. Causey was sentenced by Judge Jeanne T. Covert.
