As authorities hunt for two killers who were mistakenly freed by bogus court documents, prison officials and prosecutors across Florida scrambled to make sure no other inmates had been let out early.

The review comes three weeks after convicted murderer Joseph Jenkins walked out of prison, despite a life sentence. A week after he was let go, Charles Walker, who was also serving life, also was released.

It's not clear exactly who worked up the fake documents ordering their release. Authorities say the paperwork in both cases was filed in the last couple of months and included forged signatures from the same prosecutor's office and Chief Circuit Judge Belvin Perry. The documents also called for 15-year sentences.
