Answer:
On Christmas Day, Mr. Tonto received a call from Sakasaka police station asking for him to go to the station.
The narrator (Mr. Tonto´s daughter or son) accompanied him in the car ride, and ten minutes later they arrived at the station.
There, an officer explained that the narrator´s elder brother had been arrested for having cocaine in his shop.
They asked if they were allowed to prove his innocence and the officer agreed.
Mr. Tonto then brought out a machine from his car to scan both his son's fingers and the fingerprints on the substance to prove they didn´t match so he was exonerated and freed.
