Answer:
The agent probably knew about the murderer, because the accused only bought a ticket to return from the trip.
Explanation:
When the friend bought the travel tickets, he did not buy two tickets back, but only one, that is, he knew that his friend would not return, although he did buy two one-way tickets.
