San Juan  is the capital of Puerto Rico.
Two days after an encounter with the ghost of Esme Torres, on May 12, Special Agent Melanie Ortiz paid a visit to the FBI Field Office in San Juan. She met with Special Agent Santos and confirmed everything was back to normal. Santos inquired about the Cigar Factory Ghost Dog he read about. Melanie revealed she, Egon Spengler and Kylie Griffin concluded the entity was benevolent and only trying to warn people about Torres. Santos thanked Melanie for looking into the case and saw her off.
