— An Alaska-based soldier from Mount Pleasant will serve nearly 12 years in a military prison and be dishonorably discharged after killing a fellow soldier on Christmas morning.

Spec. Marshall D. Drake Jr. was sentenced Thursday after being convicted in a general court-martial of involuntary manslaughter.

The Anchorage Daily News reports the 23-year-old Drake was accused of shooting Pfc. Grant W. Wise, of Fairport, N.Y., in Drake’s barracks room on Joint Base Elmendorf-Richardson in Anchorage.

A witness at the court-martial said Drake and Wise continued their Christmas Eve drinking into the early morning hours, when the shooting occurred.

Prosecutors said Drake fired into Wise’s face.
