A man is in custody and accused of fatally stabbing his mother and brother at their Teaneck home on Wednesday night.

Bergen County Prosecutor John Molinelli tweeted that 60-year-old Keith Knight stabbed his 84-year-old mother Victoria Knight and his 52-year-old Ronald Knight in the home across from the Teaneck Armory.

Molinelli did not offer motive for the stabbings or any other information and said an investigation is ongoing.
