Patrolman John J. Madden, Sr. (1923-1968) was a 19-year veteran of the NYPD. He was assigned to the 104th Precinct when, on September 11, 1968, he was pursuing several suspects on foot on Stockholm Street in Brooklyn. When he complained of chest pains, Madden was taken to Wycoff Heights Hospital in Queens, where he died from a heart attack. Prior to the NYPD, Madden had served in World War II in the United States Navy Reserve. He was survived by his wife and three children. In 2023 City Councilmember Robert F. Holden proposed co-naming 70th Street, where Madden had lived, in his honor. A dedication ceremony was held on June 1, 2024. \*also known as Patrolman John Madden, Sr.
