Jacob Westervelt (sheriff)
Jacob Westervelt (1794–1881) is often confused with his brother-in-law John Jacob V.B. Westervelt (1805–1866), who was a Deputy Sheriff under him, and subsequently High Sheriff of New York City himself too (1846–1849), as well as Assistant Alderman from the 16th Ward (1844–1846). Another namesake is Jacob Aaron Westervelt (1800–1879), the shipbuilder, Alderman from the 13th Ward and later Mayor of New York City (1853–1855).
J. D. Tippit
Jefferson Davis Tippit (September 18, 1924 – November 22, 1963) was an American police officer who was an 11-year veteran with the Dallas Police Department. About 45 minutes after the assassination of President John F. Kennedy on November 22, 1963, Tippit was shot dead in a residential neighborhood in the Oak Cliff section of Dallas. Lee Harvey Oswald was initially arrested for the murder of Tippit and was subsequently arrested for the killing of President Kennedy. Oswald was charged with both crimes shortly after his arrest. However, Oswald denied involvement in either of the cases. Because Oswald was shot and killed by nightclub owner Jack Ruby two days after the killings, he could not be prosecuted for either.
