ST. GABRIEL — An Iberville Parish Grand Jury returned a true bill for Warren Mitchell, III, 25, of St. Gabriel, in connection to the stabbing death of Captain Devin Boutee of the St. Gabriel Police Department. Officials said Mitchell was Boutee’s boyfriend and an argument between the duo led up to the deadly stabbing on July 6, 2025.
The grand jury returned an indictment for second-degree murder on Friday morning, Oct. 10, 2025. That means the grand jury found there was enough evidence to proceed to a trial with formal charges against Mitchell.
UWK learned that the officer was the subject of what the Iberville Sheriff said was a request for a corruption investigation. Sheriff Stassi said days before the murder, he had asked the Louisiana Attorney General’s Office to look into allegations of corruption against Boutte.
A 911 call early Sunday morning in July reported that a man had been killed in St. Gabriel. The deceased was identified as St. Gabriel Police Captain Devin Boutte.
Iberville Parish Sheriff’s deputies, who are leading the murder investigation, arrived at the scene on Legion Dr. on July 6 to learn Boutte had been stabbed to death.
Mitchell was arrested and during questioning, documents say “Mitchell admitted to killing Devin Boutte by striking and stabbing Boutte multiple times.” It’s why a warrant was issued for his arrest and he’s now behind bars, charged with second-degree murder.
Capt. Boutte had been with St. Gabriel PD since 2012.
The Mayor of St. Gabriel, Lionel Johnson, issued a statement on Capt. Boutte’s passing:
It is with deep sadness that we announce the passing of Captain Devin Boutte, a dedicated and respected member of the St. Gabriel Police Department. Captain Boutte served our community with honor and distinction for approximately 12 years, having joined our department as an eager young man determined to make a difference.
Over the years, Devin rose through the ranks through sheer dedication and an unwavering commitment to service. At the time of his passing, he served as Captain over our Uniform Patrol Division—a role in which he led with integrity, compassion, and strength. His presence was not just felt in the department, but throughout the city of St. Gabriel. He was cherished by our residents, and his actions clearly reflected the deep love and respect he held for this community.
This year has already been profoundly difficult for our department, and the loss of Captain Boutte weighs heavily on us all. Yet, in his honor, we will carry on his legacy by continuing to uphold the mission he championed every day: to provide safety and security for all who call St. Gabriel home—and for those who visit us.
Captain Boutte will be deeply missed by all who had the privilege to know him and serve alongside him. Our thoughts and heartfelt prayers are with his family, friends, and loved ones. We ask the community to keep us in your prayers as we mourn the loss of another life taken far too soon.
