Hurricane season and heavy tourist traffic can impact response times and jail processing. Many residents in Key Largo and Marathon recommend checking the inmate search tool early in the morning or late evening when updates are more frequent. Always keep important documents secure due to the risk of flooding. Beware of phone scams claiming to be from the sheriff’s office demanding immediate payment — MCSO will never ask for payment over the phone for warrants or bonds. When calling, have the full name, date of birth, and any known booking details ready to speed up assistance.
