OKLAHOMA CITY - Today, CHARLES DEAN LACK, 56, of Wayne, Oklahoma, entered a plea of guilty on a federal charge of threatening to murder federal law enforcement officers, announced United States Attorney Robert J. Troester.
According to an affidavit filed in support of the criminal complaint, on or about August 5, 2022, the Federal Bureau of Investigation learned that Lack had communicated an intention to travel to Will Rogers World Airport (WRWA) and kill federal officers when he arrived. The affidavit further alleges Lack had previously visited WRWA on three separate occasions to determine the location of certain federal law enforcement officials within the WRWA.
On Aug. 17, 2022, a federal grand jury returned a two-count indictment against Lack. Count 1 charged him with threatening to murder federal law enforcement officers, and Count 2 charged him with interstate transmission of a threatening communication.
Today, Lack entered a plea of guilty to Count 1 of the indictment before U.S. District Judge Timothy D. DeGiusti. A sentencing hearing will be scheduled in approximately 90 days. At sentencing, Lack faces a maximum penalty of 10 years of imprisonment, three years of supervised release, and a $250,000 fine. Lack has been in federal custody since August 8, 2022.
