Married cop in Hiram’s slash is unmasked

The PBA union card that sent state Sen. Hiram Monserrate into a jealous rage after he found it in his girlfriend’s pocketbook belongs to a married cop who claims he doesn’t know her, The Post has learned.

The police officer is Walter Loor, 48, a 17-year NYPD veteran assigned to the 28th Precinct in Harlem.

Sources say Loor told police investigators that he met Karla Giraldo, 30, a year ago, possibly just before Monserrate, 42, stepped into the picture.

But Loor told The Post: “I don’t know anything about it. I don’t know her. Maybe she’s a friend.”

Prosecutors say the Queens Democrat, an ex-cop and ex-Marine, flew into a jealous rage last Dec. 19 when he found Loor’s Patrolmen’s Benevolent Association card in Giraldo’s pocketbook after she attended a Christmas party.

The two argued loudly, and Monserrate allegedly shattered a glass into Giraldo’s face, cutting her about the left eye, and leaving wounds that required 30 to 40 stitches.

The 2007 PBA card, entered into evidence at Monserrate’s assault trial, didn’t have a shield number.

In the place where the shield number is supposed to be are the words “US Navy.”

Loor’s name and precinct phone and cellphone numbers are written on the back.

The sources said Loor’s name came up in the Monserrate investigation because of the card, and the cop was questioned by Internal Affairs Bureau officers.

The bureau cops determined there was no problem because Loor’s relationship with Giraldo had nothing to do with his job or the Dec. 19 incident, the sources said.

Loor, who lives in The Bronx, told The Post that he gives out a lot of PBA cards without keeping track of whom he’s given them to.

In a dramatic video shown in Queens Supreme Court last Tuesday, Monserrate is seen throwing the card down the trash chute in the hall outside his Jackson Heights apartment.

Giraldo, wearing a black camisole, shoves him with two hands and then runs to the chute in a vain bid to recover the card.

Later, he drags her from the building as she tries to hold onto a stairway railing and a door frame.

Defense attorney Joseph Tacopina says Giraldo suffered the cuts in a freak accident when a clumsy Monserrate tripped while bringing her a glass of water.

The trial resumes tomorrow.
