An off-duty female NYPD officer is accused of shooting her ex-girlfriend and killing that woman’s new partner inside a Brooklyn home Wednesday, and the state Attorney General’s office is now investigating.

It happened just after 5 p.m. at the ex-girlfriend’s home in Bensonhurst, where police say 31-year-old Officer Yvonne Wu was waiting for the couple to arrive. Wu opened fire, wounding her 23-year-old ex-girlfriend and killing that woman’s new partner, 24-year-old Jamie Liang.
