Sergeant Thomas F. J. O’Grady (1879 - 1916) served in the New York Police Department for 12 years, until his death in 1916. While responding to a report of a stabbing at Dexter Park in Woodhaven, his horse slipped on cobblestones. O’Grady was subsequently thrown from his horse and the horse fell on top of him. Four days later, he succumbed to his injuries in Saint Mary’s Hospital. He had been assigned to the Mounted Squad at the Richmond Hill (102nd) Precinct.

In 2018, O’Grady’s name was added to the State of New York Police Officers Memorial in Albany, NY. The street co-named in O'Grady's honor in 2024 is near the site of his fatal accident.
