When William worked in Santa Fe Springs, California, back in the 90s, he told me he thought the building he worked at was haunted. "It really is," said William. "I have had more than a few incidents happen to me while I was working alone, late at night," he continued. William was working as a manager for a very busy chemical distribution company at the time. In order to keep up with his work, he sometimes had to work at night, or go in on weekends to catch up with his paperwork.
