Woman fatally stabbed in NYC bar was ‘sweet innocent’ worker from Ireland whose beau killed her: police sources

The bar worker fatally stabbed in an Irish pub in Queens over the weekend was a “sweet innocent girl” from Ireland whose boyfriend attacked her, police sources and witnesses told The Post on Sunday.

Sarah McNally, 41, who lived in Glendale, died on the floor of the Ceili House pub on Grand Avenue in Maspeth after the 6:30 p.m. assault left her bleeding from stab wounds to her neck, police sources said.

It’s not clear what sparked the slaying.

But sources said McNally’s boyfriend — with whom she’d been living for several months — barged into the bar, knifed her, then tried to leave the hole-in-the-wall bar, whose Gaelic name means social gathering.

“She was just standing there talking,” said a female patron who witnessed the chaos. “Her boyfriend came in … and he just walked right in and stabbed her. Then he started trying to stab himself. Horrible. Just horrible!”

When the cops rolled up, the suspect had a blade in each hand and was bleeding from his self-inflicted knife wounds, sources said.

Officers told him to drop the knives and tased him with their stun guns when he didn’t, sources said.

Authorities transported the unidentfied stabber to NYC Health + Hospitals Elmhurst in critical condition, according to police.

Charges against him are pending, sources said.

There was no history of domestic violence between the couple that hinted at McNally’s gruesome end, sources said.

Mike Lambe, a 62-year-old landlord who has lived about two blocks away from the bar for two decades, told The Post on Sunday that McNally was a “sweet, innocent girl from Longford,” a county in the heart of the Emerald Isle.

She had been working at the bar less than a year, he said.

“She was an innocent!” he said.

The resident said the street has its issues, including druggies and their dealers.

“It’s been getting worse and worse,” he said.
