A Long Island woman tried to resuscitate the father of her child moments after he was shot to death in his own home.

James Creekmore, 41, was shot and killed around 10 p.m. Friday as he opened the door to his North Bay Shore home, cops said.

“They saw their father get killed. There’s no words,” mourned the victim’s girlfriend Patience Daniels, 30. “I’m numb. It’s just pathetic. It’s cowardly. I can’t even call them human.”

“I have to tell my 4-year-old her father will never play with her again.”

Daniels and Creekmore shared a home near Sagtikos Parkway and North Gardiner Drive, and the gunman blasted away from inside the house — though it’s unclear whether the killer forced his way inside or was let in, police sources said.

At home at the time were the couple’s 4-year old daughter Jayla, and Creekmore’s 16-year-old twins, a boy and a girl.

Daniels’ efforts to administer CPR failed, and Creekmore was pronounced dead at the scene.

Cops have not said whether the victim knew his assailant.

“I don’t know whether it was a robbery or a vendetta,” said Daniels’ father, who refused to give his name. “I think we ought to stop making guns. When are we going to wake up?”

A neighbor said that until last night, she thought the area was safe.

“This is a quiet neighborhood,” said Latoya Jones, 34. “I’ve been here a year and a half and I’ve never had any problems. I’m shocked.”

A still stunned Daniels begged the killer to turn himself in.
