The zero-tolerance policy on letting probation violators out early followed the slaying of six people Aug. 6 at a Deltona house and the February slaying of an 11-year-old Sarasota girl, Carlie Brucia.
Prosecutors say both cases involved felons who weren't sent back to jail before the killings when they violated their probation.
State corrections officials in August ordered probation officers to lock up violent offenders for any violation of the conditions governing their release, which could be as simple as missing an appointment.
Statistics obtained by The Associated Press showed the number of probation violations pending statewide rose about five percent more than 38,000. That is nearly 2,000 more than in July.
