Jack Rybakoff, a former boxing promoter, was murdered in Manhattan's Lower East Side on July 19, 1947. An ex-convict who'd served time in Sing Sing for kidnapping, he became the third gangland murder in the span of three days. Only days earlier two longshoremen were gunned down in a Brooklyn ambush. Rybakoff was walking with a companion when he was slain. In 1933 Rybakoff turned himself in after a short time as a fugitive in Massachusetts. He was charged with two Queens' Policemen in the kidnapping of rum runner Ernest Schoening.
