MUSKOGEE, Okla. - The Muskogee County District Attorney's office is under investigation by the Oklahoma State Bureau of Investigation (OSBI).
The OSBI launched the investigation on Monday at the request of Muskogee County District Attorney Larry Moore.
Investigators will look into whether any state laws were violated during the period of time when Moore's office had access to the county courthouse security system.
The OSBI requested assistance from the FBI to determine whether any federal laws were broken.
The investigation is a result of the transfer of computers from the sheriff's office, who runs the surveillance system, to the district attorney's office.
The computers may have contained software that would have potentially allowed access to monitor the county courthouse security system.
Moore said his office did nothing wrong or illegal.
A group of attorneys also called on the OSBI to open an investigation.
Cameras and microphones, which are part of the security system, are located in hallways and inside courtrooms.
Attorneys say they often meet with their clients inside empty courtrooms whenever there is a recess.
While they knew about the security system, they were not aware that the D.A.'s office had access.
"The concern is that when we had those conversations, was somebody listening in? And if they were listening in, what disadvantage did that cause our clients?" said Muskogee attorney Lowell Howe.
Moore's office no longer has access to the feeds.
A judge delayed the start of four criminal trials until the investigation is complete.
