Answer:
The owner reasonably believed that the traveler committed felonies.
Step-by-step explanation:
Considering the fact that "the owner had just received an alert about a suspect in several armed robberies of service stations. And that the traveler and her car matched the description of the suspect."
Hence, If the jury finds in favor of the owner, the likely reason is that "The owner reasonably believed that the traveler committed felonies, " which is obvious.
Also, from the narration, it can be understood that the owner of the service station made the call to the best of his knowledge and not because he intentionally tried to delay the owner of the car.
