- How was the knocking on the door?

P answered, first 2 hours light, then 3 strong hours.

- I thought it was the ticket driver, so I opened the door. A fat man came in and a skinny man followed shortly after. They both covered their faces, only showing their eyes, they also wore gloves. Just seeing me they beat me down.

Police S again asked:

- What is the wound on your face?

P rubbed the wound with her hand and said, it was caused by the bandit's ring. S continues to ask:

- What's the ring?

P said it was a gold ring, with green stone on his face. Police S nodded in agreement and let P continue:

Answer:

Sheriff S has discovered conflicting statements of P in details:

1. First : The bandit wears a face mask, only open eyes cannot smoke.Therefore, the robber cannot be the owner of two half-smoked cigarettes on the floor in front of the wagon.
2. Second : The attendant wears gloves, why P can see exactly what color ring is.According to P's testimony, the bandit ring worn is a gold ring with green stone face.
3. Third : Two bandits said something the witness could not hear because of the loud train, but could recognize different light knocking on the door.

Only from these 3 details, police S was able to correctly judge the thief of this money theft.
