Mixon, Zachary

Tenure Summary

Zachary Mixon entered the Georgia Department of Corrections in 2015 as a corrections officer and moved up through the ranks: correctional sergeant from 2016 through 2019, correctional lieutenant in 2020, and correctional assistant superintendent across 2021 and 2022. On July 1, 2022, he became Superintendent at Treutlen Probation Detention Center — the only facility-lead posting in these records tied to a specific institution. That tenure ran through December 31, 2024. Separate annual salary records also list him as a Correctional Superintendent for calendar years 2023, 2024 and 2025, though those entries do not identify a facility. His status is listed as active; no other status is documented with a source.

One death is attributed to a facility-leadership tenure. David Eugene Schmitt, 60, died at Treutlen Probation Detention Center on January 31, 2024, when Mixon held the Superintendent role there, per the death records compiled in this file. No lawsuits naming Mixon as a defendant, no intel reports or intel events dated inside his Treutlen tenure, and no news reports naming him directly appear in the records provided.

What happened on their watch

Treutlen Probation Detention Center — Superintendent, July 1, 2022 to December 31, 2024. One death is attributed to this posting. David Eugene Schmitt, age 60, died on January 31, 2024, according to the GDC mortality record compiled in this file, which lists Mixon's role at the time as Superintendent. The record assigns the death cause category 6 and carries no public narrative; the materials provided do not describe the circumstances of the death beyond that coding, and none of the available fields establish a cause or a finding of fault. A separate record dates Mixon's Correctional Superintendent title at Treutlen to November 22, 2023.

No lawsuits against Mixon are recorded while he held the Superintendent position, and no intel reports or intel events dated within his Treutlen tenure appear in this file. Records for his earlier, non-leadership postings — corrections officer in 2015, sergeant from 2016 to 2019, lieutenant in 2020, and assistant superintendent in 2021 and 2022 — list only the roles and dates; those years are not covered by the intel-item lists, and nothing here speaks to conditions at any facility during them.

For the 2025 Correctional Superintendent salary entry, the records identify no facility, so no deaths are attributed to that entry.
