Legal proceedings have begun for four Army soldiers charged in the sexual assault of a college student at Joint Base Lewis-McChord in October.

The defendants—Cpl. Pedro Angel Ruiz, Pvt. 2nd Class Deron J. Gordon, Spc. Jadon Bosarge, and Pfc. Kallon Curiel—face multiple charges including sexual assault, indecent recording, conspiracy, and obstruction of justice, with Curiel also charged in a separate child sexual assault case.

Gordon has pleaded guilty, while the others await trial, NBC News has reported.

Each faces potential decades in prison, and the cases are scheduled to continue through November.
