Prosecutors and defense lawyers are preparing to deliver closing arguments in the court martial of a Hawaii-based Marine accused of pouring sand in the face of a fellow lance corporal who fell asleep on watch in Afghanistan.

The arguments are scheduled for Friday morning. 

Lance Cpl. Carlos Orozco III is the last of three Marines to be court-martialed for the alleged hazing of Lance Cpl. Harry Lew, who committed suicide April 3 shortly after the incident.

Orozco has been charged with assault, humiliating Lew, and cruelty and maltreatment

Another lance corporal last month pleaded guilty to assault and was sentenced to 30 days in jail and a reduction in rank to private first class. A jury later found their squad leader, a sergeant, not guilty in a separate trial.
