SAN ANTONIO (AP) The jury is deliberating the case of a Texas Air Force instructor accused of preying on female trainees in a broad military sex abuse scandal.

Maj. Patricia Gruen delivered the prosecution’s closing argument Friday and called Staff Sgt. Luis Walker a “wolf in sheep’s clothing” who took advantage of already scared Air Force trainees. But Walker’s attorney, Joseph Esparza, argued authorities offered no other evidence during three days of witnesses besides the testimony of alleged victims.
