Special ceremonies were held to mark one year since two NYPD detectives were murdered in Brooklyn. NY1's Na'eem Douglas filed the following report.

An emotional day for the families of fallen detectives Wenjian Liu and Rafael Ramos as the NYPD unveiled plaques in their honor at the 84th Precinct stationhouse in Brooklyn where they worked.

“Everyone who enters this stationhouse will be reminded of their sacrifice,” said Police Commissioner Bill Bratton.

Sunday marked one year since their death. The two detectives were murdered while they sat in their patrol car in Bedford Stuyvesant just days before Christmas. The gunman later killed himself as police moved in on him in a nearby subway station.

The pain of their loss is still fresh for the families. Detective Liu's wife read a statement written by his father.

"I'd give anything to see him and hear his voice again,” said Pei Xia Chen. “For the past year, it has been extremely difficult for our family. Thanks to everyone who reached out to us."

Dignitaries from across the city came to pay their respects and honor the detectives, including their commanding officer, who gave a heartfelt dedication to the families.

“Thank you for sharing stories and photographs of Rafael and Joe, help us cope with the grief, enable us to learn more about these great men,” said NYPD Capt. Sergio Centa. “Know that you are forever a part of our family and that we will always keep Rafael and Joe and our hearts.

After the unveiling, the ceremony moved to Tompkins and Myrtle avenue, the site of the shooting, where there was a moment of silence and a wreath was laid at 2:47 pm., the exact moment the two officers were shot. Mayor de Blasio says the occasion is a time for the city to reflect.

"In honor of detective Ramos and Detective Liu, let's rededicate ourselves,” de Blasio said. “Let's rededicate ourselves as good as they were. To being a city worthy of their memory"

Passersby are still stopping to pay their respects, but the NYPD say the wreaths will eventually be moved to stand in front of the 84th Precinct station house.
