A formal complaint has been filed with the Tennessee Department of Health regarding the conduct of a physician involved in the failed execution of death row inmate Tony Carruthers on May 21, 2026. The complaint, submitted by Carruthers’ sister, Tonya Hervey on July 15, alleges that Dr. Mark Walton Fowler engaged in unethical medical practices during the aborted procedure.
The state’s attempt to execute Carruthers was halted after execution team members spent over an hour unsuccessfully attempting to establish a backup intravenous (IV) line. While a primary line was established, the team’s failure to secure the secondary access required by state protocol led Governor Bill Lee to grant a one-year reprieve.
According to legal counsel for Carruthers, including ACLU attorney Maria DeLiberato, who witnessed the proceedings, the team made over a dozen attempts to access veins in the inmate’s arm, hand, and foot before Dr. Fowler attempted to place a central line. DeLiberato described the scene as distressing, noting that Carruthers exhibited visible signs of pain, including wincing and groaning, throughout the ordeal.
Allegations of Misconduct
The complaint against Dr. Fowler levels several specific accusations regarding his professional conduct and qualifications:
—Ethical Violations: The filing contends that Dr. Fowler violated medical ethics by participating in the execution process, an act widely condemned by major medical organizations such as the American Medical Association, which views involvement in capital punishment as antithetical to the mandate to "do no harm."
—Procedural Negligence: It is alleged that Dr. Fowler injected the anesthetic lidocaine without first verifying the inmate’s potential for allergic reactions.
—Lack of Recent Experience: The complaint challenges Dr. Fowler’s qualifications, noting that he had not performed a central line placement in over a decade. In a separate federal lawsuit, documents revealed that Dr. Fowler last performed the procedure around 2013 during his time in an emergency room and that he currently lacks active hospital privileges.
Dr. Fowler has declined to comment on the allegations. Representatives for the Tennessee Department of Correction have also offered no public comment, while the Tennessee Department of Health maintains that information regarding specific complaints and investigations remains confidential until formal charges are substantiated.
Medical experts have offered varying perspectives on the criticism. Dr. Ervin Yen, a retired cardiac anesthesiologist who has observed executions in Oklahoma, stated that while a decade-long gap in performing a central line procedure is not automatically disqualifying, the broader concerns surrounding the process remain significant.
Regarding the family’s claim that Carruthers suffered a stroke resulting in partial paralysis, Dr. Yen noted that such an outcome is highly unlikely to be caused by the attempts to establish an IV.
The case of Tony Carruthers, who was convicted for the 1994 murders of Marcellos Anderson, Delois Anderson, and Frederick Tucker, continues to draw scrutiny regarding the state's execution protocols and the medical professionals recruited to carry them out.
