The funeral service for Officer Wenjian Liu, the second NYPD officer killed while seated in a patrol car last month, will be held today. Liu was killed along with Officer Rafael Ramos by Ismaaiyl Brinsley in Brooklyn on Dec. 20. Ramos was buried last weekend. 

According to the Associated Press, thousands of police officers who have traveled from all over the country are expected to gather for the 32-year-old's service this morning. A traditional Chinese ceremony led by Buddhist monks will be followed by the standard police ceremony. Thousands also attended Liu's wake at Aievoli Funeral Home in Brooklyn yesterday

NYPD Commissioner Bill Bratton issued a memo to the department yesterday asking officers to refrain from making bold statements at Liu's wake. This comes after officers turned their backs to Mayor Bill de Blasio while he spoke at Ramos' funeral last Saturday. The following day, Bratton called the stunt "very inappropriate." The Associated Press adds that de Blasio will also speak at Liu's funeral. 

Liu, a seven-year veteran of the police department, was covering for another officer who was late when he was killed. The Associated Press reports that he will be buried at Cypress Hills Cemetery.
