Chilling video shows woman executed on NYC street

Surveillance footage obtained by The Post captured Nichelle Thomas, 52, walking on Fourth Avenue in Park Slope at around 1 p.m., apparently heading to a store on the corner of St. Marks place.

She’s about to open the door, when a woman sprints up behind her and pulls out a gun.

The attacker then shoots her target point-blank in the back of the head and runs off.
