Last Saturday the 40-year-old Breitkopf was wearing plainclothes, and carrying a rifle pointed down when he walked into a scene that would ultimately cost him his life.
Breitkopf was accidentally shot by an MTA police officer in a case of mistaken identity.
After police had shot and killed 21-year-old Anthony DiGeronimo, a self described anarchist, his colleagues are said to be devastated.
Today Breitkopf was remembered as a devoted husband and father of two young boys and his dedication to the community.
Brietkopf, a 12-year veteran of the force, was assigned to the elite special operations bureau.
He was a volunteer firefighter as well.
Mourners attended a tearful wake for him Wednesday, at the Selden firehouse where he volunteered.
