Slain NYC Teen Saniyah Lawrence’s Grandmother Tears Up Her Accused Killer Boyfriend

The grandmother of a slain Harlem teenager tore up the girl’s teenage boyfriend who was accused of stabbing her, insisting to The Post on Tuesday he was never good enough for her “beautiful” granddaughter.

Saniyah Lawrence, 16, was killed Sunday night when her baby-faced boyfriend, 18, Zyaire Crumbley, allegedly stabbed her in the neck at an apartment on Adam Clayton Powell Jr. Boulevard and then fled, police said .

Hours after Crumbley turned himself in, Lawrence’s paternal grandmother, Eileen Lawrence, said she always had an inkling about the boyfriend.

“I only met him a few months ago and that was it. I’ve made it my mission not to even meet him again,” the grieving grandmother told the Post.

“I didn’t think he was good enough for her.”

After Tuesday night’s memorial service for the murdered teenager in Harlem, Eileen Lawrence described her eldest granddaughter as a “beautiful person.”

“Everyone loved her. Wherever she went, she was like a ray of sunshine,” she said.

“She became a magnet. People just went to her. People she didn’t know became her friends and loved being around her. That’s the kind of person she was.”

The grandmother added that Lawrence’s grieving father Justin was “devastated” over the teen’s killing.

“This is his firstborn so he’s really crushed because he knows that’s carelessness — it didn’t need her to die the way she did and it broke my son,” she said.

“My son is literally broken.”

Crumbley, who has six previous robberies to his name, has since been charged with his girlfriend’s murder.

He is accused of stabbing Lawrence around 5.40pm on Sunday after the two got into an argument.

In the moments after the fatal attack, Crumbley was caught on surveillance video fleeing the apartment building and going on the run.

Lawrence was taken to Harlem Hospital, where she was pronounced dead.

Police then released a youthful-looking mug shot of Crumbley in a bid to track him down before he surrendered to officers Monday afternoon.

While neighbors told The Post the pair had a history of fighting, police sources said it did not appear Crumbley had a history of domestic violence with the teenage victim.

Still, advocates of domestic violence were among those who addressed the mourners at Lawrence’s vigil Tuesday night.

“Unfortunately we stand before you today because we committed a senseless crime. We had a child who was murdered,” said Stephanie McGraw, founder and CEO of the Harlem-based domestic violence nonprofit WARM.

“We cannot eradicate domestic violence alone. It will take a collective village of all of us to say enough is enough,” she continued.

“If you see something, we want you to say something, because what you say could save lives.”

Around 100 people attended the vigil, where mourners released white balloons in honor of the 16-year-old.

Lawrence’s funeral will be at Harlem’s Unity Church on December 20.
