The victim’s family claims in a lawsuit that two cops heard the desperate screams of the Chinatown woman who was stalked by a homeless stranger and murdered in her apartment — and even spoke to her killer through the door — but failed to help.

Christina Yuna Lee, 35, was attacked as she entered her Chrystie Street building around 4:20 a.m. on Feb. 13, 2022, by an assailant who snuck in behind her.

Neighbors called 911 after hearing her cries for help “for at least five minutes” while she was being brutally butchered.

Two unidentified officers from the 5th Precinct, located about three blocks away, responded to the 911 calls in four minutes “and heard Ms. Lee screaming for help,” according to the Manhattan Supreme Court filing against the city and the cops.

They “failed to gain entry to Ms. Lee’s apartment until Ms. Lee had been stabbed more than 40 times by her attacker and succumbed to her injuries,” according to her aunt, Boksun Lee, in a court filing.

They even spoke to her alleged killer “through the closed door of Ms. Lee’s apartment,” according to the lawsuit.

“Despite having reason to believe Ms. Lee’s life was in imminent danger, [the officers] failed to gain entry to Ms. Lee’s apartment or otherwise provide her with any potentially life-saving police or medical assistance at that time,” the lawsuit claims.

It took more than an hour for additional officers to arrive, and the Emergency Services Unit cops finally forced open the apartment door.

Lee’s body was discovered inside, and Assamad Nash, 25, whose lengthy criminal record included robbery and petty larceny, was discovered hiding under a mattress.

He was arrested and charged with murder.

“Ms. Lee’s death was caused by the wrongful acts of the defendants,” her family alleges in the litigation, which was first reported by the Daily Beast.

The NYPD declined comment on the litigation.
