The airman found dead Oct. 8 at F.E. Warren Air Force Base in Wyoming was a security officer under investigation for the fatal shooting of an airman at the base on July 25, the Air Force said Friday.
Airman 1st Class Marcus White-Allen was identified Friday as the airman found dead on base. He was assigned to the 90th Security Forces Squadron, 90th Missile Wing, at the base.
“White-Allen was under investigation as a subject in relation to an on-base shooting incident in July 2025 that resulted in the death of Airman Brayden Lovan,” the base said in a statement. “White-Allen was being investigated as a subject on suspicion of making a false official statement and involuntary manslaughter in connection with the July incident.
The Air Force did not describe the circumstances of White-Allen’s death. Lovan’s and White-Allen’s deaths remain under investigation.
The Air Force confirmed that an obituary for Marcus Tyione White-Allen posted online by a Fort Wayne, Ind., funeral home was the airman who died at the base. White-Allen joined the Air Force and completed basic training at Lackland Air Force Base in Texas in 2023 before being assigned to F.E. Warren.
Lovan, 21, from Greenville, Ky., was killed July 20, 2025, at F.E. Warren Air Force Base. He was a Remote Targeting Engagement System Operator with the 90th Security Forces Squadron. The squadron provides security for the base, which is a key operations center for nuclear-armed Intercontinental Ballistic Missiles.
Lovan was killed by a Sig Sauer M18 pistol. The Air Force initially investigated whether the gun had discharged without the gun user pulling the trigger. Air Force Global Strike Command ordered a pause on the use of the pistol, and the Air Force mandated a service-wide safety inspection of all Sig Sauer M18s.
The Air Force previously reported that a service member had been arrested on charges of involuntary manslaughter, obstruction of justice and making a false official statement. The statement Friday did not explicitly say White-Allen was the person facing the charges.
When it announced an airman’s Oct. 8 death, the 90th wing’s commander, Col. Terrance Holmes, offered condolences for the fatality.
“It is with deep sadness that we face the loss of a member of the Mighty Ninety, and on behalf of our entire team, I offer my deepest condolences to the family and friends of the lost individual.”
Col. Jeremy Sheppard, commander of the 90th Security Forces Group, issued a statement this month regarding the deaths.
“If your intentions are pure, I will ALWAYS have your back,” Sheppard said.
Sheppard told the group that while most members were “doing the right thing every day,” those who were not should consider “then this might not be the right place for you.”
Sheppard called on the security group to return to its role of safeguarding the base.
“We did talk about the recent fatalities, but the larger message was a call to action: to block out the noise, refocus and recalibrate on what matters most,” he said.
White-Allen’s death was the fourth involving an airman from F.E. Warren. An airman was found dead Sept. 30, and authorities linked the death to the fatal shooting of a female victim in Fort Collins, Colo., that was classified by local law enforcement as a murder-suicide.
Airman Jadan Orr was charged with involuntary manslaughter for the Aug. 16 shooting death of Senior Airman Joshua Aragon, 23, when he fired an AK-47-style rifle through the wall of his off-base apartment, hitting Aragon. Orr has pleaded not guilty to the charge and is awaiting trial.
