‘I Told You Not to Mess with Me’: 5-Year NYPD Veteran Allegedly Shot Her Ex-Girlfriend, Killed Other Woman in Love Triangle


Yvonne Wu crime scene

A 31-year-old officer with the NYPD allegedly shot and killed her ex-girlfriend’s new lover at Bensonhurst, Brooklyn home on Wednesday, then matter-of-factly and in a “calm, collected” manner admitted to police that she shot “someone.”

Yvonne Wu is accused of shooting her 23-year-old ex-girlfriend Jenny Li and killing Li’s new love interest Jamie Liang, 24. Wu’s ex survived. Liang was found in the living room, shot in the chest (possibly multiple times); Li was found shot once in a bedroom. Police believe all three parties knew each other and that the suspect was in the residence when the two victims came home. Wu was scheduled to work a night shift hours later.

Here’s the police account of what happened, as obtained by Law&Crime:

On Wednesday, October 13, 2021 at approximately 1700 hours, police responded to a 911 call of two females shot inside of 7901 19th Avenue within the confines of the 62 Precinct. Upon arrival, officers observed a 24-year-old female with a gunshot wound to the chest and a 23-year-old female with a gunshot wound to the torso. EMS also responded to the scene and transported the victims to Maimonides Hospital where the 24-year-old female was pronounced deceased, and the 23-year-old female remains in serious but stable condition. A 31-year-old female was taken into custody at the scene and the investigation remains ongoing. Charges are pending.

An NYPD spokesperson confirmed that Liang, of East 20th Street in Manhattan, was the homicide victim.

Patrol Borough Brooklyn South Assistant Chief Michael M. Kemper briefed reporters on Wednesday night outside of the crime scene.

He said that the suspect is a 5-and-a-half-year veteran of the NYPD assigned a Patrol Borough Brooklyn South precinct, reportedly the 72nd Precinct. Kemper did not name the officer during the press briefing, but he did say she was in custody and taken to a hospital for an evaluation. He said the motive was believed to be domestic in nature and that the suspect confessed to shooting someone.

“I would describe her as calm, collected and very forthcoming,” Kemper said of Wu. “Simply put, she confessed. That’s all I’m going to say.”

Kemper said that that the residence belonged to a 23-year-old woman, who he believed to be Wu’s ex-girlfriend. Video at the scene from earlier in the day showed Wu being taken into custody.

Subsequent reporting from the New York Daily News and New York Post said that when Jenny Li called 911, Wu could be heard in the background yelling “I told you not to mess with me!” and “That’s what you get”— even as the victims pleaded for their lives.

Kemper said he could not confirm that the weapon was a service weapon, but he did say the weapon and ballistic evidence were recovered at the scene.

The Daily News quoted an unnamed friend of Liang’s, who called Wu a “psychopath.” The friend said that Wu and Li broke up about a month ago:

One of the dead woman’s friends told the Daily News that Li and Wu lived together in Bay Ridge until about a month ago, when they broke up.

“She was possessive. Jenny Li just couldn’t take it anymore,” the 21-year-old friend said. “This cop is a psychopath. She was stalking her ex for a month.”

Wu was sitting on Li’s bed when she and her new girlfriend came home, the friend said.
