The disease was recently diagnosed in a person who lives nearby. Officials set six traps at Frances E. Willard Intermediate School on the 1300 block of North Ross Street.
One trap caught an opossum. It was taken to be tested for typhus, which is a flea-borne bacterial infection sometimes spread by feral cats.
Officials found things thrown into the other traps, which caused them to close. There are no suspects, and police said security cameras didn't catch anything.
