Over the next two years, an extensive manhunt was conducted in both the United States and Europe, with reports of Buchalter hiding in Poland and Palestine. On July 29, 1939, Thomas Dewey requested that the City of New York offer a $25,000 reward for Buchalter's capture, citing a string of unsolved gangland murders. On August 24, 1939, Buchalter surrendered to FBI chief J. Edgar Hoover in front of a Manhattan hotel. The surrender deal was allegedly negotiated by the columnist and radio broadcaster Walter Winchell. It was later revealed that Buchalter had been hiding in New York City during his entire time as a fugitive.
