NYPD Inspector Michael Ameri "shot himself in the head Friday" following FBI questioning in a corruption investigation targeting the police department and city hall as reported by the Daily News. Ameri "was friendly with Jeremy Reichberg, one of two Brooklyn businessmen at the center of the corruption probe involving high-ranking police officials accused of accepting gifts in exchange for favors" as reported by dnainfo. Reichberg and the other businessman under scrutiny, Jona Rechnitz, both have political ties to Mayor Bill de Blasio, and Hizzoner said he was "saddened" over Ameri's suicide. Of course, de Blasio probably didn't lose any sleep over the tragic death.
