Monroe County Marathon Jail

The Monroe County Marathon Jail is located in Marathon, Florida. It is one of three Monroe County Detention Facilities that is operated by the Monroe County Sheriff's Office.

This facility houses adult males and females—both misdemeanor and felony inmates—who have been arrested by local county or municipal law enforcement.

Some of the inmates have been tried and sentenced to jail or the Florida Department of Corrections. However, most inmates have not yet been tried by the courts, so they are presumed innocent until proven guilty.

Florida VINE

The Florida VINE system is a service through which victims of crime can search for information regarding the custody status of their offender, and to register to receive phone calls and e-mail notifications when the offender’s custody status changes. 

This service is provided to assist Victims of Crime who have a right to know about their offender's custody status. Click this link to register.

Inmates being held for U.S. Immigration and Customs Enforcement (ICE), the Florida Department of Corrections (DOC), or charges from other counties will not be found by going to the VINE Link above. You will have to call the jail.

Bonding someone out of the Monroe County Jail

If an inmate has bondable charges, he or she can bond out at any time. For further information on bonding out an inmate, or to find out the bond amount on an inmate, call 

There are several ways for an inmate to be released from jail including posting bond, qualifying for pretrial release, being released resulting from a court hearing, etc.

The method (cash/surety) and amount of money needed for bonding someone out of the Pre-Trial Detention Center depends on their charges. Most crimes, but not all crimes, are bondable offenses.

When you pay a cash bond, it is refunded to you when all court appearances have been made and the case is discharged, dismissed, or a not guilty verdict rendered. If the arrestee fails to appear or is found guilty, the money will be forfeited. 

When you use a Bail Bondsman for a surety bond, you will not get a refund.
