Q: Do I have to move the group token if I confirm a clue card matching an adjacent space on the escape track?
A: No, it is your choice whether to move the group, and you may move up or down the track depending on how you plan to catch the Suspect.
Q: Can I move the group token multiple spaces on the same turn?
A: Yes. Each time you confirm a clue card matching the color of an adjacent space on the escape track, you may choose to move the group token. Since it is possible to confirm 3 cards on a turn, it is possible to move the group token up to 3 spaces within that turn (if the clue cards confirmed are the correct colors for doing so).
