Dressed in an olive-green suit and tie and carrying a black bag, Mr. Johnson hid behind a van outside the firm's office, then approached Mr. Ercolino and shot him once in the head with a .45 caliber semiautomatic handgun, authorities said.
Mr. Ercolino graduated from SUNY Oneonta in 1992 with a major in business and a minor in fashion and rooted for the Mets and Jets, according to his LinkedIn profile and Myspace pages, the latter of which appeared to be last updated several years ago.
