FORT BRAGG, N.C. (AP) — The wife of a seriously wounded soldier is expected to take the stand as the sentencing hearing for Army Sgt. Bowe Bergdahl resumes.

Prosecutors told a judge they intend to call Shannon Allen to the stand Monday to discuss a traumatic brain injury her husband suffered. National Guard Master Sgt. Mark Allen was shot in the temple during a search for Bergdahl, who walked off his post in Afghanistan in 2009.

Bergdahl has pleaded guilty to desertion and misbehavior before the enemy. He faces up to life in prison. Prosecutors are using wounds to several service members who searched for Bergdahl as evidence to convince the judge that he deserves a stiff punishment.
