This is the moment a woman calmly walked up to a mum-of-one and shot her dead in an 'execution-style' murder.
Delia Johnson, 42, was gunned down on a busy street in Brooklyn, New York, on Wednesday, the Daily Star reports.
She suffered a serious gunshot wound to the head and injuries to her leg, with the mum later dying in hospital.
Police are now hunting down the woman who killed her and officers have released footage of the shocking murder.
The CCTV footage shows Delia standing in front of a shop on a street, where a group of people are hanging around.
The suspect, described as a dark-skinned adult female in her mid-20s, walks up behind Delia and pulls out a handgun before firing a shot towards the back of her head.
Delia falls to the ground and the gunwoman turns around and gets in a white car, which then flees the scene.
Officers patrolling nearby arrived within moments and found a faint pulse and began performing CPR despite the victim lying unconscious and unresponsive.

She was taken to a hospital where doctors pronounced her dead.
Delia's brother, Mathis Johnson, told the Daily News that the attacker may have followed his sister from the funeral of a pal earlier in the day.
He said: "She was at a funeral earlier in the evening for an old neighbourhood friend to pay her respects, and then this happened.
"It was horrible. That lady executed my sister."
"The woman was heartless, she took a sister, a daughter away, she took a mother."
Investigators have a possible suspect ID but have not yet made an arrest, a police source told Fox News.
New York Police said the shooter was with a heavy build and long blonde hair. She was last seen wearing a black long-sleeve shirt, black tights, a silver belt, black and white sneakers, and a white purse.
