WICHITA, Kan. — Authorities in south-central Kansas say a 20-year-old McConnell Air Force Base airman has been killed and three others injured in an east Wichita shooting.

The shooting occurred around 2 a.m. Saturday at an apartment where a party was being held. Police say arriving officers found the wounded 20-year-old unresponsive and performed CPR, but he died at the scene.

Two other men, ages 21 and 22, were taken to a hospital with injuries not believed to be life-threatening. A 19-year-old woman had already been taken by a private vehicle to hospital with serious injuries. Police say she is expected to survive.

Col. Richard Tanner, commander of the 22nd Air Refueling Wing, tells station KAKE that the base “is deeply saddened by the loss of one of our airmen.” Air Force officials are withholding the man’s name pending notification of his family.

No arrests had been reported by midday Saturday.
