When choosing a lawyer, Google his name to see what information turns up online. Many times you will see complaints about a particular lawyer from previous clients. Similarly, you can perhaps see other cases he's been involved in and the results. Combine the lawyer's name with the city to minimize the chances of getting an unrelated result.
