Steven Deering #

Introduction #

Steven Deering is a former K-9 officer with the Clarksville Police Department in Clarksville, Tennessee, whose employment ended after an internal investigation into his deployment of a police dog during the June 29, 2026 arrest of Darius Chappell, a 34-year-old man who died in custody five days later. The department announced that Deering was no longer employed as of September 1, 2026, after completing an internal investigation and disciplinary process connected to the K-9 use-of-force incident. Cellphone video of the arrest circulated widely on social media, drawing an August protest, demands for transparency, and scrutiny of the department’s K-9 policies, while the Tennessee Bureau of Investigation continues a separate, ongoing investigation into Chappell’s death.

Background Information #

Deering served with the Clarksville Police Department as a K-9 officer working alongside a police dog partner. In April 2026, the department announced that he had been recognized as its 2026 Officer of the Year by the American Legion CSM Gary W. Crisp Post, citing his service to the community alongside his K-9 partner. After the incident that ended his career, FOX 17 News obtained Clarksville PD’s K-9 policies, which outline when officers may deploy a dog and the medical care and reporting requirements that follow a deployment.

The man at the center of the case, Darius Chappell, had moved to Clarksville for a fresh start, according to his family. Earlier in June 2026, he was arrested on domestic assault charges for allegedly slapping a woman, and days later an order of protection was filed against him. At the time of the June 29 encounter, he was subject to an outstanding warrant for a parole violation.

The Controversy or Incident That Led to Their Cancellation #

Allegations. The use-of-force claims in this section arise from a Clarksville Police Department internal investigation whose findings were never disclosed. They were never admitted by Deering, never criminally charged, and never adjudicated in court; his termination is an administrative employment outcome, not a judicial finding of misconduct. Deering is entitled to the presumption of innocence, and Chappell’s death remains unadjudicated, with the TBI investigation ongoing.

On June 29, 2026, Montgomery County sheriff’s deputies — with Deering assisting — attempted to arrest Chappell on the outstanding warrant outside a Dutch Bros. store on Fort Campbell Boulevard. Authorities said Chappell ran from officers as they approached, resisted arrest, and tussled with them, and that he was tased several times. Cellphone video showed Chappell on the ground as several officers tried to take him into custody; a police K-9 was deployed and appeared to bite him while officers held him down, remaining on him for nearly a minute before an officer pulled the dog away.

The Montgomery County Sheriff’s Office said Chappell was taken to a hospital after his arrest, treated, and medically cleared for booking into the Montgomery County Jail. He was found unresponsive in his cell during a routine security check around 3 a.m. on July 3 and pronounced dead at Vanderbilt of Clarksville — five days after the arrest. His cause and manner of death have not been released. Deering was placed on administrative leave while CPD conducted an internal review of the K-9 deployment.

On September 3, 2026, the department announced that Deering had been terminated effective September 1, stating that “the investigation and resulting personnel actions were handled in accordance with departmental policy, City Code, and personnel procedures.” CPD did not disclose its specific findings, identify any policy violations, or explain the basis for the termination.

Public Reaction and Consequences #

Allegations. The accounts below come from Chappell’s family and supporters, not from any court or disclosed investigative finding. No criminal charge has been brought against Deering, and he is presumed innocent.

In August 2026, Chappell’s family and supporters held a protest calling for more transparency and access to records related to his death. After the firing was announced, family spokesperson Marquell Bridges of Building Bridges spoke on the family’s behalf, saying Chappell’s mother “breaks down every day into tears” and describing Chappell as “the light of their family.” “We want a conviction. We want arrest and charges against the officer that operated in evil and inhumane way,” Bridges said.

Current Status #

Deering is no longer employed by the Clarksville Police Department as of September 1, 2026. No criminal charge against him has been reported, and CPD has released no findings, citing the ongoing TBI investigation: “Due to the ongoing TBI investigation, no other information will be released at this time,” the department said. The TBI’s investigation into Chappell’s death remains ongoing, and his cause of death has not been made public.

Impact on Their Career/Life #

The termination ended Deering’s tenure as a Clarksville K-9 officer roughly five months after the department celebrated him as its 2026 Officer of the Year. The case has kept pressure on the department over its K-9 deployment policies — including the medical care and reporting rules that follow a deployment — and over its refusal to disclose the investigation’s conclusions while the TBI’s death inquiry continues. The video of the arrest spread widely enough to make the K-9 deployment a local flashpoint, and Chappell’s family continues to demand criminal charges, a decision that now rests with authorities separate from the department that fired Deering.
