The military is moving forward with a court martial against accused Fort Hood shooter Major Nidal Hasan.

An Article 32 hearing is scheduled to begin March 1. It's similar to a civilian grand jury.

A special investigator will give a recommendation on moving forward based on the evidence presented. The army appointed Colonel James Pohl as the investigating officer.

Hasan is charged with 13 counts of murder and 32 counts of attempted murder.

His lawyer has said that Hasan may plead not guilty by reason of insanity.
