Did you know that the “medical doctor” that botched two death penalty executions started out his career as a lawyer defending death penalty cases?
Dr. Mark Walton Fowler, a family medicine physician based in Union City, Tennessee, has served as the physician on Tennessee’s execution team for recent lethal injections, including the September 30, 2026, attempt on Christa Pike.
He earned a law degree from the University of Tennessee in 1984 and worked for about three years as a public defender, representing capital defendants and securing non-death sentences.
In the mid-1990s he retrained in medicine at the University of Tennessee College of Medicine. He has held a Tennessee medical license since 2000 with no reported board reprimands; his listed specialty is family medicine. His practice has included emergency-room work (including at Baptist Memorial Hospital-Tipton), family medicine, and medical directorships at weight-loss and aesthetic clinics, a wound-care facility, and the Interstate Blood Bank (corporate medical director since 2012). Court records indicate he does not currently hold hospital privileges.
Fowler has said in a deposition that he began participating in executions after a friend who was the state’s prior execution physician invited him to observe one around 2018 so he could eventually take over the role. Under the protocol he is responsible for examining the inmate to confirm death and, if needed, attempting a central line.
Reporting has placed him at the executions of Oscar Smith (May 2025) and Byron Black (August 2025), the aborted May 2026 attempt on Tony Carruthers (in which peripheral IV access failed and a central-line effort was unsuccessful; he stated he had last performed a central line around 2013), the August 2026 execution of Anthony Darrell Hines (where he reported declaring the time of death), and the September 30, 2026, attempt on Christa Pike.
So his only role is central line but he isn’t performed it since 2013 and someone thought he was good to go?
His identity became public after a warden named him following the Black execution; states generally shield execution-team members. He has written for The Patriot Post and has been described in profiles as a Methodist, outdoorsman, and political conservative.
