Killer Brooklyn mom haunted by thoughts of slain 4-year-old

The 26-year-old mom was arrested Thursday for the savage killing of her little boy Zamair, who became the target of her homicidal rage when he accidentally dropped an egg on the floor, sources said.

Zamair was just three months old when his dad carved up his grandmom with a 2-foot Black & Decker electrical saw and stuffed the body parts into plastic trash bags.

McLean-Smith said the couple met in a group home, and her family was opposed to the wedding.

“We weren’t against her, we were against Bahsid,” said McLean-Smith. “My nephew was no good. He was a bully, he didn’t work, he lived off his mother. We couldn’t understand what she saw in him.”

Bahsid McLean is serving 25 years to life in prison for the killing, which he punctuated by posing for a selfie while clutching his mother’s head.

McLean-Smith said she only learned about the fatal beating of the little boy via a Saturday morning phone call from an old acquaintance.

She had only seen Zamair once, when the boy was less than a year old, and will now never see him again, she said.

“I cried this morning,” said McLean-Smith. “I did a lot of crying. How do you beat a child that bad? How do you beat a child to death with a broom? What made you so angry? He’s 4 years old.”

Court papers indicated Bahsid and Zarah filed for divorce in April 25, 2016, and the case was settled on Nov. 15, 2016.

McLean’s sister said she was still grappling with the twin tragedies.

“I would have never thought my brother would have done that to my mother,” Lovett said. “I would have never wanted my nephew to die like that. She (Zarah) was a sweet girl. I just don’t understand.”

Lovett added that she was outraged that Zarah told reporters during a jailhouse interview that her boyfriend was Zamair’s father.

“No, she didn’t. She was going to hide it.”

Lovett was also curious if anyone notified her brother of his son’s death.

“He should be notified,” she said. “It’s a death in the family.”
