The wife of a murdered New York policeman has given birth to their daughter two and a half years after his death.

Wenjian Liu was killed in December 2014 while sitting in his patrol car in Brooklyn. His partner, Rafael Ramos also died when Ismaaiyl Brinsley walked up to their vehicle and fatally shot them.

Hours earlier, Brinsley wrote on Instagram: “I’m Putting Wings on Pigs Today.’’ He later committed suicide.
