US Says Accused Bike-Path Killer Saipov Threatened to Behead Jail Officer Reuters NEW YORK - A man charged with killing eight people by driving a truck down a lower Manhattan bike path in October 2017 recently threatened to decapitate an officer at the jail that has housed him since his arrest, U.S. prosecutors said. In a Tuesday night court filing, the Department of Justice said Sayfullo Saipov made the threat on Dec. 18, after the officer's supervisor told Saipov to stop obstructing a security camera in his cell at the Metropolitan Correctional Center in Manhattan. Prosecutors said they want to introduce the incident as "proof of future dangerousness" during the penalty phase of Saipov's case, if he is convicted at his April 20 trial. .
