A soldier who worked as a corrections officer at the military’s primary detention facility will spend more than a decade on the other side of prison bars for sexual offenses and domestic violence.
Pfc. J Quan Fields, 23, was sentenced by a military judge to 13 years at the Naval Consolidated Brig Miramar in California as part of a plea deal, according to an Army statement Tuesday.
In addition, Fields will be reduced to the rank of private and dishonorably discharged. He was a prison guard at Fort Leavenworth, Kan.
Fields had pleaded not guilty to one count each of rape and communicating a threat, but last week he was convicted on both charges by the judge in his general court-martial.
In addition, he pleaded guilty to one specification each of sexual assault, domestic violence, communicating a threat and violating a military protection order.
As part of the plea agreement, another domestic violence charge and one other charge of violating a military protection order were dismissed, the statement said.
An investigation into Fields was launched in 2024 after his pregnant wife, who was also a service member, reported that he had grabbed her by the neck during a fight at their home and had previously threatened to kill her, according to the statement.
Investigators also learned of a sexual assault accusation stemming from a dispute at a party he hosted at his home in October 2024. The woman in that case was a co-worker of Fields, the Army statement said.
Authorities also found a second woman who said Fields sexually assaulted her at her home in December 2024 after the two met at a local bar, according to the statement.
Fields was placed in pretrial confinement in April 2025 after repeatedly violating a military protection order issued for his wife by the Army Criminal Investigation Division.
Fields’ crimes “represent a profound betrayal of the trust placed in him as a service member and a corrections specialist,” Derek Tilton, an Army CID special agent, said in Tuesday’s statement.
After completing his sentence, Fields will be required to register as a sex offender.
