NYPD said  the robbery took place just before 1 a.m. at the Burger King on East 116th Street near Lexington Avenue on January 9th, where Kristal Bayron Nieves was working as a cashier when an unknown masked man, dressed in all black, entered the restaurant and demanded money. 

During the altercation a female manager at the restaurant was punched in the face and a male customer was likely pistol whipped. Kristal gave the gunman the money, according to reports it was $100. The gunman went to leave, turned around and shot the teen in the torso according to the New York Post. 

Kristal was rushed to hospital where she died of her injuries. 

Police have released a video of the suspect.

Update: Winston Glynn, 30, a former employee of the same East Harlem Burger King was arrested for the murder of Kristal Bayron-Nieves.

According to the New York Post “Investigators pored over hours and hours of surveillance footage from the 116th St. 6 train subway stop and recognized the suspect walk into the station hours before the deadly shooting wearing different clothing and carrying a backpack. Police identified him as the gunman by the way he walked and the white cord from a pair of earbuds hanging from his pants. They spotted him on camera going back into the station after the shooting.”
