A widow has welcomed a “miracle baby” more than a two-and-a-half years after her husband, an NYPD, detective, was killed in the line of duty.

On Dec. 20, 2014, Detective Wenjian Liu and his partner, Detective Rafel Ramos, were both shot and killed while sitting in their police cruiser in Brooklyn. The gunman took his own life after killing the men.

On the night of the incident, Liu’s wife, Sanny Liu, asked to preserve her husband’s sperm so she could someday have a child.

According to WCBS, Sanny Liu said she had a dream the night after her husband died that he was handing her a baby girl.

“I got pregnant through the [in-vitro] fertilization procedure,” said Sanny Liu. “And I told my friend, ‘It’s going to be a baby girl.’ My friend said, ‘No, you haven’t even checked the sonograms,’ but I was right!”

Sanny Liu was thrilled to welcome baby girl Angelina and said she can’t wait to tell her that her father was a hero.
