Chief McGinnis is the chief of police in River Heights.
He is on good terms with Nancy, considering how much detective work she does.
Nancy mentions that the Chief vouched for her when she asked for a copy of the tape that came with the bomb in Rick Arlen's dressing room in 1999.
Chief McGinnis has to arrest Nancy when she is under suspicion of setting the old Town Hall on fire in 2011, but he lets her out of her cell to put together evidence in the police station. When her friends collect enough evidence and she presents it to him, he lets her out.
- A McGinnis stayed in room #18 of the Ryokan Hiei.
