Karen Sisco is a fictional Deputy United States Marshal created by novelist Elmore Leonard. Karen was born and raised in Miami, Florida. She grew up in law enforcement, as her father was a Miami police officer. He had hoped Karen would steer clear of a dangerous career and settle down with someone safe, like a doctor or a lawyer. But she always knew she was destined to follow in her father's law enforcement footsteps. Deputy U.S. Marshal Karen Sisco is one investigator who does all the hard work to keep Miami's Gold Coast clean of fugitives, and she does it in a right way.
