At first glance, the paperwork ordering the release of two convicted murderers serving life sentences in a Florida prison looked legitimate.

So the guards at Franklin Correctional Institution put one of the men on a bus and opened the gates for the other to ride away with family. Authorities now say prison officials were duped by the court documents, which included a fake motion from a prosecutor and a judge’s forged signature.

The release led to a manhunt across Central Florida, but the inmates have a significant head start. Joseph Jenkins was let out Sept. 27, and Charles Walker was freed Oct. 8. Both are 34.

Chief Circuit Judge Belvin Perry, who presided over the Casey Anthony murder trial in 2011, said Thursday there were several red flags that should have attracted attention from the court clerk’s office or the Corrections Department. Namely, it’s rare for a judge to order a sentencing reduction, and even more uncommon for the request to come from prosecutors.

“One of the things we have never taken a close look at is the verification of a particular document to make sure it’s the real McCoy,” said Perry, whose name was forged on the paperwork. “I knew that that was always a possibility, but you never want that possibility occurring in the way that it did.”

It wasn’t clear exactly who wrote the paperwork or how authorities discovered the error.In both cases, the forged paperwork included motions from an Orlando prosecutor to correct “illegal” sentences, accompanied by orders from Perry granting the motions.

“These two individuals are out. They shouldn’t be, and we want to get them back in custody,” Orange County Sheriff’s Office spokesman Angelo Nieves said Thursday. “This shouldn’t have happened, but it did, and our concern is to get these individuals into custody.”

Jenkins was found guilty of first-degree murder in the 1998 killing of an Orlando man. Jenkins and his cousin were convicted in the shooting death of Roscoe Pugh in a botched robbery.

Upon hearing of Jenkins’ release, his former attorney, Bob Wesley, said he was sure “it wasn’t a cunning master plan.”

Wesley, now the public defender for metro Orlando, recalled his client’s crime and said Jenkins broke into a home of someone he knew and was “not smart enough to pull his ski mask down.”

Jenkins’ cousin Angelo Pearson was also sentenced to life and is serving time at a different Florida prison.

Walker was convicted of second-degree murder in a 1999 slaying in Orange County. He told investigators that 23-year-old Cedric Slater was bullying him and he fired three shots intending to scare him.

Department of Corrections spokeswoman Misty Cash didn’t know which man had been dropped off at the bus station, but said prison officials routinely work with inmates who are getting out.

“If they need a bus ticket, we’ll provide that for them,” she said.

In a statement, Corrections secretary Michael Crews said his agency is reviewing records to make sure no other inmates had been released in a similar fashion. He also said the agency followed policy and procedure when it released the men.

State Rep. Darryl Rouson, the Democratic ranking member of the House Justice Appropriations Subcommittee, said the Legislature should hold hearings to examine the agency’s procedures.

“If these two convicted murderers were let go by the Florida Department of Corrections, something must change,” he said.

Leesa Bainbridge, a spokeswoman for the Orange County Clerk of Courts, said the office moves thousands of pages of court documents a day and currently has no way of authenticating those that pass through to other agencies.

“We’re kind of like the post office,” Bainbridge said. “It comes in and we move it along.”
