RALEIGH, N.C. (AP) – Military and civilian authorities have charged an HIV-positive soldier with assault with a deadly weapon, accusing him of having unprotected sex with a partner he did not tell about the infection.

Military and civilian prosecutors have not decided who will prosecute the case against Pfc. Johnny Lamar Dalton, said Maj. Tom Earnhardt, a spokesperson for the 82nd Airborne Division at Fort Bragg.

Dalton, 25, was arrested last week and was being held Tuesday in county jail on a $50,000 bond, said sheriff’s department spokesperson Debbie Tanna. She said inmates were not allowed to give interviews, and a jailer said the soldier had not been appointed an attorney.

Along with the assault count, Dalton faces civilian charges of committing a crime against nature and misdemeanor assault inflicting serious injury. Earnhardt said he faces the same charges in the military’s criminal justice system.

An arrest warrant filed by county officials accuses Dalton of not telling his male partner, an 18-year-old civilian, that he has HIV, the virus that causes AIDS. The teen’s mother alerted authorities to the relationship after her son fell ill and told her about it; he has tested positive for HIV. Tanna said she did not know whether Dalton was the source of the teen’s infection.

Dalton is assigned to the 22nd Aviation Support Battalion, which is part of the 82nd Airborne, Earnhardt said. He was ordered by his commander in November not to have unprotected sex after it was discovered he was HIV positive. State law also prohibits a person infected with HIV from having sex unless condoms are used and requires that sexual partners be notified.
