Officials on Tuesday added 18 names to a memorial wall for New York Police Department officers who died in the line of duty.
Mayor Bill de Blasio and Police Commissioner William Bratton oversaw the annual dedication ceremony in Battery Park, in lower Manhattan.
Many of the officers whose names were inscribed died from illness related to their search and recovery efforts after the terror attacks on Sept. 11, 2001. One detective honored died in 2003. Twelve of the officers honored died last year.
Among the names unveiled were those of Detective Rafael Ramos and Detective WenJian Liu, who were shot and killed inside their patrol car in December by an anti-police protester who later killed himself.
