The Pre-Trial Services unit of the department was established in February 1990 to offer a supervised release program for felony defendants who are released from jail on surety or PR bonds. This program helps to alleviate jail overcrowding and allows defendants to hire their own attorneys. The primary focus of supervision is to offer a means of accountability to the courts for defendants facing convictions for any felony level offenses. Pre-Trial Supervision will sometimes include a requirement for ignition interlock devices, in home alcohol monitors, SCRAM units or electronic monitoring equipment. Pre-Trial Supervision Officers monitor the defendants to ensure they appear for their court hearings and abide by the terms of release.
