The mother of a young Chinese immigrant beaten to death by a drunken, pipe-wielding rapist—a total stranger to his victim—confronted the killer in a Queens courtroom on June 1.

Guihua Yu wailed in her native Mandarin, “I want to kill that man. I want to kill him now. I want him dead now,” as the accused killer was walked into court to face charges in the May 16 murder of Yu Yao.

Giuhua, 55, tried to jump over people in the courtroom to reach Carlos Salazar Cruz, but was restrained by five court officers who moved in and carried her out. As the court officers carried Giuhua from the courtroom, the sobbing woman cried out in Mandarin, “I want my daughter back.”

Guihua was later wheeled out on a stretcher and taken by ambulance to a nearby hospital for observation, authorities said.

Inside the courtroom, prosecutors said they plan to seek an indictment upgrading charges faced by Cruz to include second-degree murder and possibly first-degree murder. Cruz is currently charged with attempted murder and aggravated sexual assault in the May 16 attack.

Yao, 22, was left brain dead after Cruz stalked her along a Flushing street and pulled her into an alley where he raped her and beat her with a metal pipe.

Police sources said Cruz was “very drunk” when he dragged the woman into an alley on 41st Road near Main Street at about 9 p.m. on May 16 and viciously beat and raped her.

Eyewitnesses told police the drunken, pipe-wielding Cruz grabbed Yao as she was walking on 41st Road. Cruz smacked Yao in the head with the pipe and dragged her, nearly unconscious, into the alley.

An eyewitness called 911 when he spotted Cruz fighting with Yao at the beginning of the attack. “It only took a few minutes before she was unable to fight back,” police sources said.

Cops responding to the call arrived as a bloodied Cruz was trying to leave the scene.

If convicted of murder, Cruz would be sentenced to life in prison without the possibility of parole.
