SAN ANTONIO – The first Air Force instructor convicted of rape in a sex scandal at one of the nation's busiest military training centers has died in prison.
Staff Sgt. Luis Walker died at a hospital Sunday night after being found unresponsive two days earlier in his cell at Fort Leavenworth, Kansas.
Prison spokeswoman Denise Haeussler says the cause of death is being investigated.
She says no further details will be available until the Army criminal investigators have completed their work.
