The daughter of fallen officer Wenjian Liu and his wife Pei “Sanny” Xia Chen was baptized at St. Patrick’s Cathedral on Saturday surrounded by her NYPD family.

Commissioner James O’Neill and Chief Terence Monahan were among the many officers present for the christening of Angelina Liu at the landmark church.

The girl’s hero dad was slain alongside his partner, NYPD officer Rafael Ramos by a cop-hating madman, while the pair sat in their patrol car in Bedford-Stuyvesant, Brooklyn, on Dec. 20, 2014.

The night of the murder, Liu’s devastated widow had a foreshadowing dream in which her husband handed her a baby and told her “Baby, here’s the baby. Here’s a girl.”

Liu and Chen were only married three months and were planning to start a family. As the officer lay dying in the hospital, his wife asked the doctors if they could preserve his sperm.

Chen gave birth to their baby, Angel – whose full name is Angelina – on July 25, 2017, after conceiving through in-vitro fertilization.
