The 54-year-old man who stunned workers at an upscale Manhattan cafe Sunday when he jumped out of their walk-in freezer was identified Monday as an accused double murderer who had recently been released from jail in Boston. NBC4 reports that Carlton Henderson, who fell unconscious while threatening Sarabeth’s workers with a knife and later died, had been indicted last June for his alleged role in the 1988 murders of William Medina and Antonio Dos Reis. The homicides remained unsolved for decades, NBC4 adds, but were reopened by a cold-case team in recent years. After his lawyer successfully filed a motion to suppress evidence, Henderson was released on his own recognizance on August 1. Authorities have not yet determined how or why he came to be in a freezer on the Upper West Side of Manhattan.
