Two convicted murderers were released from prison by mistake on in the last month in Florida and are still on the loose according to authorities in that state. The men were set free after the prison system received forged papers authorizing their release.

34-year-old Joseph Jenkins, convicted of first degree murder and sentenced to life in prison for shooting a homeowner during a home invasion robbery in 1998, was released from prison on September 27th, and 34-year-old Charles Walker, convicted of second degree murder in 1999 and sentenced to life, was released on October 8th. Both prisoners were released after a forged release document with the Ninth Circuit Chief Judge Belvin Perry’s signature on it was sent to the Florida Department of Corrections.

“It is quite evident that someone had some knowledge of the judicial system and how the judicial system operates,” Judge Perry told CBS

Authorities have no idea where the documents came from or who sent them but say that the forgery was a simple one. Spokesperson for the Orange County Clerk of Court Leesa Bainbridge stated, “We have thousands of pieces of paper coming through this office. There’s no way to backtrack and say whether this was mailed in, faxed, or left in a dropbox.”

The Department of Corrections denied any wrongdoing in the incident, and a spokesperson for the department, Misty Cash said, “We initiated our typical procedure for an inmate release. The department followed our procedures and protocols to the letter.”

The paperwork, headed, “Order Granting Motion to Correct Illegal Sentence,” looked official and and the pages looked legitimate and explained that each man was not sentenced properly and so were due to be released. Both documents for each man were very similar in content.

Florida has said that the state is altering its policy on prisoner releases as a result of the incidents. No longer will the Department of Corrections just check with the Court Clerk on early releases, but will check with the Judge who’s signature is on the order.
