A now 18-year-old Paterson teen will plead guilty to aggravated assault after a video of the attack surfaced on social media.
A video - recorded by an unidentified 16-year-old - where Kristian Gonzalez is shown punching Cesar Nejara for no reason on Dec. 7, 2015.
Nejara was transported to the hospital with serious injuries.
Gonzalez and the other teen were charged with aggravated assault and endangering an injured victim. Under the plea deal reached, Gonzalez will have to serve no less than 85 percent of a three-year sentence.
Gonzalez's sentencing is scheduled for Tuesday in Passaic County Superior Court.
