HACKENSACK, N.J. (AP) — Prosecutors have dropped a manslaughter charge against the son of a former aide to Democratic New York City Mayor Bill de Blasio's wife in the stabbing of a teenager in New Jersey.

Defense attorney Jeffrey Lichtman says the Bergen County prosecutor's office dropped the charge against 20-year-old Khari Noerdlinger after he pointed to inconsistencies in their case.

Prosecutor Gurbir Grewal says the manslaughter charge was dropped Sept. 7, but weapons charges remain.

Noerdlinger was charged in the 2016 death of 16-year-old Savion Lewallen.

Authorities said Lewallen went to Edgewater with four accomplices in an apparent bid to rob Noerdlinger. Lewallen was killed during the confrontation.

Noerdlinger's mother is Rachel Noerdlinger, who resigned in 2014 after a string of damaging disclosures about her personal life, including Khari's arrest on trespassing charges.
