A granddaughter of the 92-year-old Queens woman who was raped and murdered last month by an illegal immigrant spoke at a White House event on border security Friday — and slammed New York’s city’s sanctuary city policy.

Daria Ortiz, one of victim Maria Fuertes’ grandchildren, spoke at the invitation of President Trump, who also delivered remarks on border security to members of the National Border Patrol Council, the union repping Border Patrol agents.

“I am the granddaughter of the 92-year-old woman who was raped and murdered in Queens. She raised her grandchildren while working hard to give us a future. Unfortunately, my grandmother had to be example of why something like this, [these] horrific crimes should never happen,” an emotional Ortiz said in the South Court Auditorium in the Eisenhower Executive Office Building.

“Our families hope is that her death was not in vain and that preventive measures are put into place to ensure nothing like this ever happens to anyone again. The tragedy is that this could have been avoided had there been no sanctuary law,” she continued, struggling to maintain her composure.

“The tragedy is my grandmother is not ever going to be here again. The man that is responsible for this should have never had the opportunity had his multiple offenses been ignored. The system not only failed our family, but they failed our city.”

Trump — who also mentioned the tragedy in his State of the Union Address — ripped Gotham’s sanctuary city policy, asserting that Fuertes would be alive if her alleged assailant, Reeaz Khan, 21, an illegal immigrant from Guyana, had been turned over to the feds after earlier busts.

“I asked for the criminal to be taken in, but he was released under New York sanctuary laws. If ICE was allowed to do what they could she would still be alive right now,” the president said.

As The Post reported last month, Immigration and Customs Enforcement said it lodged a detainer request with the NYPD for Khan on Nov. 27 — the same day he was busted for allegedly attacking his father during a fight in their South Richmond Hill home.

Khan, 21, was accused of using a broken ceramic mug to slash the chest and arm of his father, 41, who then had to be hospitalized.

Khan was charged with misdemeanor assault, criminal possession of a weapon and harassment, and released without bail after being slapped with a temporary order of protection for his dad, records show.

About six weeks later, Khan was busted in the sexual abuse and slaying of Fuertes after she was found with her clothes pulled above her waist and near death on a Richmond Hill sidewalk at about 2 a.m. on Jan. 6.

Trump echoed the criticism of Thomas Decker, New York field officer of enforcement and removal operations for ICE.

“It was a deadly choice to release a man on an active ICE detainer back onto the streets after his first arrest included assault and weapon charges, and he now faces new charges, including murder,” Decker told The Post.

The president also touted construction of his long-promised border wall, saying it was “virtually impossible to climb over the top” because of its design and the fact that it will be painted black.

The black paint, he said, would make it “virtually untouchable … because of the sun hitting it. The black absorbs the heat.”

He said that immigrants entering the country illegally would “not only have to be a very good climber,” but that they would have to bring in a hose to spray it and cool it down, noting there weren’t many hoses available at the border.

He added “cameras, drones [and] a lot of different contraptions” would make it nearly impossible to breach or jump.
