Faced with possibly spectral contamination, the property manager of a Conifer Road business complex asked JCSO to investigate the unearthly residue haunting her hallways. Sometime the night before, she said, entities unknown had discharged the full contents of a fire extinguisher inside the building’s dark and forbidding service passage, leaving the place thickly coated with fire suppressant chemicals. Eerily, the depleted extinguisher was found still attached to the wall in its accustomed position. It could have been someone who works in the building, she said, or any member of the public. She didn’t say it could also have been ghosts, but it could also have been ghosts.
