Wichita ? An airman accused of having unprotected sex without telling partners he was HIV positive faces a military hearing to determine if there’s enough evidence for a court-martial.

The hearing for Tech. Sgt. David Gutierrez is Tuesday at McConnell Air Force base, where he is stationed. No immediate decision is expected.

The 43-year-old sergeant is accused of violating military law by having unprotected sex with at least 11 different people, including some he met at so-called swinger parties.

Gutierrez is charged with assault and violating his squadron commander’s October 2009 order to notify his sexual partners about his HIV status. Gutierrez also has been charged with indecent acts, adultery and obstruction of justice.
