BUNNELL, Fla. — The Flagler County Sheriff’s Office has concluded its internal investigation into an off-duty shooting involving former Master Deputy Bryan Jackson, finding he violated agency policies before resigning from the department.
According to the sheriff’s office, Jackson submitted his resignation Thursday after investigators determined he violated agency firearms and standards of conduct policies stemming from an Aug. 27, 2025, shooting in the Mondex area.
The incident occurred when Jackson was firing at a makeshift berm on a neighboring lot. During the shooting, a stray bullet struck a nearby home and grazed an 11-year-old boy inside.
On May 1, the Flagler County Sheriff’s Office submitted a criminal charge of culpable negligence, a misdemeanor under Florida law, to the State Attorney’s Office for the Seventh Judicial Circuit.
After reviewing the evidence, including a reconstruction of the incident and forensic firearms analysis conducted by FBI experts in Quantico, Virginia, prosecutors declined to file criminal charges against Jackson.
Following that decision, the sheriff’s office reopened its administrative investigation.
Investigators concluded Jackson violated agency policy by using an agency-issued or approved firearm loaded with non-issued ammunition and by using the weapon for practice outside an authorized Flagler County Sheriff’s Office firing range.
The investigation also found Jackson violated the agency’s Standards of Conduct policy, which carries penalties up to and including termination.
Because Jackson resigned before the disciplinary process concluded, the sheriff’s office said it could not impose discipline. However, as required by Florida law, the completed internal investigation will be forwarded to the Florida Criminal Justice Standards and Training Commission for review and any action it deems appropriate.
The sheriff’s office said Jackson is not eligible for rehire.
“After a lengthy and thorough investigation, the State Attorney’s Office reviewed the facts in this case and decided not to file criminal charges against Mr. Jackson,” Chief of Staff Mark Strobridge said. “Mr. Jackson’s decision to resign concludes the administrative process, but our commitment to professionalism, accountability, and public trust remains unchanged.”
The sheriff’s office also noted that before the internal investigation concluded, Jackson’s daughter, who had been employed as a probationary deputy sheriff, also resigned from the agency.
Jackson joined the Flagler County Sheriff’s Office in 2013.
