A veteran Mobile County Sheriff’s Office deputy walked away from the agency last week while internal affairs was still looking into his conduct — and because he resigned, the investigation ends with no findings at all.
Deputy Terry Sexton, an investigator assigned to the sheriff’s office’s SORNA unit, tendered his resignation while pending findings from the internal review, MCSO spokesperson Lori Myles confirmed in a phone call Friday.
An investigation left unresolved
Because the matter is a personnel issue, Myles said she could not provide additional information about what prompted the inquiry or what investigators had uncovered. What she could confirm is the outcome: with Sexton’s resignation, the internal investigation was closed as inconclusive, resulting in no findings.
The sheriff’s office did not release the nature of the conduct under review.
A career that crossed three agencies
Sexton brought an unusual resume to the sheriff’s office. According to online records of his career, he spent nine years as a firefighter with Mobile Fire-Rescue before joining the Mobile Police Department in 2018. He moved to the Mobile County Sheriff’s Office in 2022 and was assigned to the agency’s narcotics and vice unit through 2025. Most recently, he worked in the SORNA unit — the division responsible for tracking and verifying compliance by registered sex offenders under the federal Sex Offender Registration and Notification Act.
That kind of cross-agency background is common in South Alabama law enforcement, where officers and deputies move among municipal, county and fire service employers, carrying certifications with them. It also means an unexplained resignation raises questions across multiple former employers, none of which are obligated to disclose personnel details.
Why resignations close cases
The dynamics at play are familiar to law enforcement watchers. Internal affairs investigations are administrative proceedings, not criminal ones, and their practical leverage over an officer ends the moment the officer’s employment does. A resignation before findings are issued leaves the record without an adjudication — no suspension, no termination, no exoneration — and the officer leaves eligible to seek certification elsewhere unless the state’s peace officer standards body takes separate action.
MCSO has not said whether the matter was referred to any outside agency or whether Sexton faces any criminal exposure. With the internal file closed and the deputy gone, the public record may never say what investigators were examining.
Sexton’s departure is the second personnel exit to surface from the sheriff’s office in recent weeks as the agency works through internal reviews, and it comes as the office continues to balance transparency against the personnel privacy rules that constrain what any agency can say about a departing employee.
