Hello Buckwheat - S3.E18

Vinnie calls in Roger Lococco to take over the case, then holes up in a seedy hotel in Seattle. Frank is more interested in looking for Vinnie than in nailing Volchek. Paul orders Frank to continue the case and offers him another agent, which Frank refuses. Roger takes over as sheriff. Dan moves to Seattle to support Frank and look for Vinnie.
