On Monday afternoon, Nanuet FD's 8-Tower joined forces with New City FD's 9-Tower to display the American Flag over the funeral procession of fallen NYPD Detective Joseph Lemm as it traveled down the NYS Thruway.

Joseph Lemm, 45, a 15-year NYPD veteran, was killed in a Dec. 21 suicide bombing in Afghanistan while serving with the 105th Base Defense Squadron. Five other American service members also were killed in the bombing, including New York Guardsman Staff Sgt. Louis Bonacasa, 31, of Coram.

Several other Rockland County fire departments also lined the various highway overpasses of the NYS Thruway as the procession traveled from Steward Air Force Base in Orange County to Lemm's hometown of West Harrison, NY.

The NYPD said viewing will be at Saint Anthony of Padua Church in West Harrison in Westchester County on Tuesday, from 2 to 5 p.m. and 7 to 9 p.m.

A funeral Mass will be celebrated at St. Patrick’s Cathedral in midtown Manhattan on Wednesday at 10 a.m.

Lemm will be buried at Gate of Heaven Cemetery in Hawthorne, the NYPD said.
