Washington ? Supervisors of the Army psychiatrist accused in the massacre at Fort Hood sanitized his performance appraisals in the years prior to the shootings, according to government documents obtained by The Associated Press that reveal concerns about Nidal Hasan at almost every stage of his Army education.

Officers in charge of Hasan piled praise into the alleged gunman’s record despite knowing he was chronically late for work, saw few patients, disappeared when he was on call and confronted those around him with his Islamic views.

The materials also disclose concerns that the psychiatrist-in-training might have been developing a psychosis, according to the documents, yet no mental health evaluation was done.

Defense Secretary Robert Gates released an internal Pentagon review last week that found several unidentified medical officers failed to use “appropriate judgment and standards of officership” when reviewing Hasan’s performance as a student, internist and psychiatric resident.
