It’s a deal a Northwest Side man may be wishing he had refused. The 44-year-old man told San Antonio police he paid more than $12,000 for a used car that never materialized

In an arrest affidavit, police said the man pointed the finger at Alfonso Hernandez, 33, telling them he’s the person who accepted and cashed his check for $12,600, and promised to deliver a used car.

The man told police Hernandez had led him to believe that he buys vehicles at auctions. He said after he paid Hernandez, he was told the vehicle would be delivered within a few days, but he never heard back from him, the affidavit stated.

The alleged victim said he sent Hernandez a letter in May, demanding the return of his money, but the letter was returned by the post office, the affidavit stated. Police arrested Hernandez Sunday on a theft charge.
