The gunman shot dead by cops after opening fire on the steps of the Cathedral of St. John the Divine on Sunday had a long rap sheet that included an attempted murder bust, according to records and sources. Luis Vasquez, 52, was arrested on the Upper West Side for attempted murder in 1990, and on an assault charge there a year earlier, sources said Monday. Vasquez, of the Bronx, was also hit with a drug sale charge in 1989, as well as a marijuana charge in the Bronx in 2012 and a turnstile-jumping offense in 2007.
