Police have identified the body of a man found dead a day after the Kentucky Derby in a barn at Churchill Downs. Adan Fabian Perez, a 48-year-old from Guatemala, had been working for a horse groomer since 2008. A Louisville police spokeswoman says there is evidence of foul play, though it's unknown if there is a connection to the race. "We are still trying to determine what led to the incident. At this point we don't have anything pointing to the fact that this had any association with Churchill Downs or the Derby itself," she said.
