At 1 pm on Friday, July 4th 2014, a rich man was killed in his own house in New York. His wife called the police and the police suspected all the people there. The wife said she was sleeping. Their neighbors said they had gone to a wedding. His driver said he went to the bank. Their maid said she went to the supermarket. The guard said he visited his wife. After questioning these people, the police arrested one person at once. Who do you think the police arrested and why?

The police arrested the driver, and the reason for this is that his alibi didn't hold up given the specific date of the crime. The driver claimed he went to the bank, but the crime occurred on July 4th, which is Independence Day—a national holiday in the United States. On this day, banks are typically closed, so his statement about going to the bank was likely false, making him a prime suspect.
