One ill-advised text message just cost a retired Tampa Army colonel two years in federal prison.
A retired U.S. Army colonel in Tampa was sentenced to 24 months in federal prison on Feb. 11, 2026, after admitting he sent a photograph of a classified U.S. Central Command email to a woman he had been dating. Prosecutors say the image revealed the number of targets and operational details for a planned U.S. military operation, information they contend could cause serious damage to national security.
U.S. Attorney Gregory W. Kehoe announced the sentence, saying Kevin Charles Luke, 62, pleaded guilty on Oct. 7, 2025, and admitted he “abused a position of public trust,” according to a press release from the U.S. Attorney's Office for the Middle District of Florida. Court documents show Luke served in both active duty and reserve components of the Army from 1981 until his retirement with the rank of colonel on June 30, 2018, and that he later worked as a civilian employee at U.S. Central Command in Tampa. The press release notes Luke held a Top Secret/Sensitive Compartmented Information security clearance while in service and as a civilian employee.
Local reporting says Luke repeatedly acknowledged his nondisclosure obligations, signing a Standard Form 312 as recently as February 2019, and that in October 2024 he texted a woman, “sent to my boss earlier, gives you a peek at what I do for a living,” then followed up by sending a photograph of a government email he had authored using a classified account, per Tampa Bay 28. The station's report cites court records saying the image contained Secret-level markings that Luke himself added and that the photograph revealed a future operational date, the means of execution and the goal of the mission.
How Prosecutors Say the Leak Unfolded
Prosecutors told the court the photo disclosed actionable details, including the number of planned targets, and that its unauthorized release could be expected to cause serious damage to national security. The investigation was handled by the U.S. Air Force Office of Special Investigations and the Federal Bureau of Investigation, and the case was prosecuted by Assistant U.S. Attorney Lindsey Schmidt and Trial Attorney Leslie Esbrook of the Justice Department's National Security Division, according to the U.S. Attorney's Office for the Middle District of Florida. U.S. District Judge James Moody Jr. imposed the 24-month federal term at sentencing.
Legal Obligations and What Is at Stake
The Standard Form 312 is the federal nondisclosure agreement signed by cleared personnel that Congress has described as imposing lifetime obligations to protect classified material, according to Congress.gov. That legal duty underpins the government's contention that Luke “abused a position of public trust,” a point reflected in local reporting by Tampa Bay 28.
Why Tampa Cares
U.S. Central Command is headquartered at MacDill Air Force Base in Tampa, which makes mishandling CENTCOM materials a local concern for both military and civilian personnel in the region, according to U.S. Central Command. Security analysts say the case highlights persistent insider-threat vulnerabilities when cleared personnel mix personal devices and classified systems, a pattern discussed in recent coverage by Military.com.
Federal prosecutors say the sentence should serve as a reminder that long service and prior clearance do not shield someone from criminal liability when they transmit classified material outside authorized channels. For Tampa's defense community, the case is an immediate prompt to review safeguards and tighten the use of personal devices around classified systems.
