Judge Perry on Monday ordered that judicial assistants begin logging all demands for changes to inmates’ sentences and that the clerk of the courts verify with the judge or his judicial assistant whether an order was issued legitimately.

At the news conference on Tuesday, Mr. Bailey said investigators were particularly interested in the activities and procedures in the Orange County Clerk of Courts office, which received the forged documents for Mr. Jenkins and Mr. Walker in the mail and processed them. “We’re going to be camping out with the clerk’s office,” he said.

An inmate named Nydeed Nashaddai succeeded in getting out of a Pinellas County jail in 2009 by using fake release forms. He was captured 16 hours later and sentenced to 20 years for escape. He was then sent to the same Franklin County prison from which the two most recent escapes occurred. Mr. Bailey said he did not yet know whether Mr. Nashaddai passed along his scheme to fellow inmates like Mr. Walker and Mr. Jenkins.

Another escape was thwarted in 2011 when a former Orange County sheriff’s office homicide detective found that release documents filed with the county clerk contained inconsistencies. The Orlando Sentinel reported that the inmate, Jeffery Forbes, 30, was serving a life sentence for attempting to kill a deputy sheriff, who was paralyzed in the shooting. Mr. Forbes, who was trying to get out of the Franklin Correctional Facility, was charged with forgery and escape on Oct. 8, the same day that Mr. Walker was released from the prison using similarly faked documents.

Given that Mr. Forbes’s attempt had been investigated shortly before the two most recent escapes, Mr. Bailey was asked whether there had been carelessness in the handling of such matters, and whether word should have gone out to prison authorities and others about additional potential forgeries.

“There was no carelessness — we talked about it with 20 state attorneys in the summer,” he said. “We’re trying to confirm whether there are more out there.” As for the two inmates, he said, “I don’t know what talents they had, but somewhere along the line some documents that looked good were produced.”
