The crazed boyfriend of a Queens bar worker was charged with murder after he allegedly knifed her to death at work – then stabbed himself, cops and sources said.
Marcin Pieciak, 36, was also charged with criminal possession of a weapon after authorities found him still holding a pair of bloodied knives he used to stab 41-year-old Sarah McNally in the neck at the Ceili House pub on Maspeth’s Grand Avenue Friday evening.
Pieciak remains in the hospital suffering from his own stab wounds, which witnesses told The Post he inflicted on himself after attacking McNally.
It remains unclear what sparked the violent attack.
Both were rushed to a hospital after the attack, with McNally succumbing to her wounds before she arrived. Pieciak was initially listed in critical condition.
A native of Langford, Ireland, McNally’s murder has left communities on both sides of the Atlantic “in a state of shock” since the Friday attack.
“Rest in peace my beautiful niece Sarah, we are heart broken, Love you always,” McNally’s aunt, Mary, posted on Facebook on Easter Sunday.
“It’s very cruel. People struggle to say the right words at this time and there’s little anyone can say to make things better for Sarah’s parents,” Langford Councillor Martin Monaghan told the Irish outlet RTÉ News.
Another Langford politician, Fianna Fáil Joe Flaherty, called McNally a “wonderful young woman, bright, vivacious, witty and charismatic.”
The couple had been living together for several months, sources told The Post, and when Pieciak burst into the pub around 6:30 p.m. and attacked McNally.
By the time police arrived, McNally was lying bleeding on the floor while Pieciak was bleeding from neck and back wounds with knives in his hands.
Officers used a stun gun on Pieciak when he refused to drop the weapons, sources said.
“We’re just shocked by the news Sarah is no longer with us. She was a staple of the bar and of Maspeth. We’d always see her,” Queens resident Peter Cappelli told CBS News.
“I send all my condolences and our love to her family and everyone who is gonna miss her. She was the best,” he added.
