Police say an arrest has been made in the killing of a Williamsbridge man who was shot in the head just steps from his home.

Jasriri Emanuel, 21, faces a murder charge for allegedly shooting Ricardo Bygrave, 22. The violence unfolded in front of a deli located at 724 Bronxwood Ave. on April 2.

Officers discovered Bygrave just before 9:30 p.m. with a gunshot wound to the head, according to authorities.

EMS rushed him to NYC Health + Hospitals/Jacobi, where he died.

Police say Emanuel lives just blocks away from both Bygrave and the deli.

Surveillance video captured the gunman arriving at the deli and walking inside. A short time later, he exits and begins arguing with Bygrave.

It's unknown if they knew each other or what sparked the confrontation.

Emanuel faces additional charges, including manslaughter and criminal possession of a weapon.
