SHREVEPORT, La. (AP) — An Air Force electronic warfare journeyman has pleaded innocent to a murder charge accusing him of stabbing and slitting his roommate's throat while they were temporarily assigned to a base in Guam. 

News agencies report that court-martial proceedings began Monday for Isaiah Edwards. He is charged with killing 20-year-old Bradley Hale of Montgomery County, Texas.

The Air Force says it cannot release Edwards' age, and won't release his hometown out of privacy and safety concerns for his family.
