A former New York City police officer has been sentenced to 27 years in prison for shooting and wounding her ex-girlfriend and killing the ex-girlfriend’s new love interest.

Former officer Yvonne Wu, 34, was sentenced Wednesday in state court in Brooklyn after pleading guilty in June to manslaughter and attempted murder for shooting Jenny Li and Jamie Liang.

Wu was off duty on Oct. 13, 2021, when she used her NYPD-issue gun to shoot Li, her former girlfriend, and Liang, Li’s new partner. Liang was killed and Li survived with serious injuries.

“The moment was a living nightmare, having to watch a life being taken in front of my eyes and being able to do nothing about it,” Li said at the sentencing, according to the Daily News.
