Delia Johnson: cops nab suspect in shocking killing of NYC mom

It was a crime that shocked not only New York City, but the entire nation: the execution style slaying of a mother on a crowded Brooklyn sidewalk.

Now, more than three months after Delia Johnson was killed, cops have finally taken a suspect into custody.

The 42-year-old suspect was picked up by authorities in Jacksonville, Fla. on Monday and will now be extradited to the Big Apple to face charges for the Aug. 4 killing of Johnson in Crown Heights.

NYPD Police Commissioner Dermot Shea expressed relief over the arrest in a post to Twitter.

You can run, but the long arm of the law will find you,” Shea wrote.

“The woman responsible for the August 4th murder of a #Brooklyn woman has been apprehended by our partners in Jacksonville, Florida.”

Johnson was shot at point-blank range from behind as she was talking on the phone on Franklin Avenue, a busy street in the central Brooklyn neighborhood.

Harrowing surveillance footage released by police shows the suspect walk up to Johnson and shoot her in the head before nonchalantly walking back to a double-parked SUV and driving away.

Johnson’s relatives had previously said they recognized the female shooter as a one-time close family friend. The NYPD has not confirmed any connections between the two.

“I just hope that you realize what you did and [I] wonder what made you do such a thing,” Johnson’s 17-year-old daughter, Ladeya Jenkins, had said at her mother’s wake.
