SAN ANTONIO (AP) — The case of an Air Force instructor accused of preying on female trainees at a Texas base embroiled by a sex abuse scandal remained in the jury’s hands Friday.

Staff Sgt. Luis Walker was a “wolf in sheep’s clothing” who took advantage of already scared Air Force trainees, a prosecutor said Friday. His attorney, Joseph Esparza, argued that authorities offered no evidence during three days of witnesses besides the testimony of alleged victims.
