Yvonne Wu was allegedly holding out hope to reunite with ex-girlfriend

The off-duty NYPD officer who allegedly shot her ex-girlfriend and killed the woman’s new lover may have snapped because she was clinging to hope that they’d get back together, a high-ranking police source told The Post Thursday.

Officer Yvonne Wu, 31, had recently split with her ex, Jenny Li, 23, but was still spending the night on occasion at Li’s home in Brooklyn — and may have lost it when she saw her there with another woman, the source said.

“She was still staying there on and off. She was still staying there some nights. It’s not that strange, maybe she thought it could still work out,” the source said.

Wu, who works at the 72nd Precinct and lives on Staten Island, allegedly opened fire on Li and her 24-year-old new lover, Jamie Liang, at the home on 19th Avenue near 79th Street in Bensonhurst Wednesday night, according to police.

“When the cops get there, she says, ‘I shot them both. The gun’s inside,’ calm as can be,” the source said.

Liang was found with a bullet wound to the chest and was taken to Maimonides Medical Center, where she died. Li was in serious but stable condition on Thursday, police said.

The tragic love triangle came after Wu and Li dated for two years then broke up three weeks ago, according to cops.

“This is a shock. Wu was a quiet sweet person,” another police source said.

Wu, a five-year NYPD veteran, was likely waiting inside the home before the two victims arrived but it wasn’t immediately clear how she entered, according to police.

She was undergoing an evaluation at the NYU Langone hospital in Brooklyn Thursday.
