LOS ANGELES (AP) — The Los Angeles Times is on the verge of a sale that would take it from its Chicago-based parent company and put it in the hands of a local billionaire doctor. Dr. Patrick Soon-Shiong would pay Tronc Inc. $500 million for the newspaper and the San Diego Union-Tribune, a person with knowledge of the deal told The Associated Press on Tuesday. The person, who spoke on condition of anonymity because the sale hadn't been finalized, said the deal was coming together quickly, but cautioned it could still fall apart. Soon-Shiong is a major shareholder of Tronc.
