The motion, which was filed by defense attorneys and released Friday, was altered Tuesday to black out a section that stated Holmes was a patient of University of Colorado psychiatrist Dr. Lynne Fenton, The Denver Post reported.
The motion made headlines as very little information has been released in the case because of a gag order put in place by District Judge William Sylvester.
No explanation was given for why the motion was redacted -- five days after it had been published on the Colorado Judicial Branch's Web site.
Denver attorney Dan Recht speculated Sylvester made the redaction, not the defense or prosecution.
"It's possible the judge realized he made a mistake in releasing that motion because he may have realized that he violated his own gag order," Recht said.
Holmes is facing charges for opening fire inside an Aurora movie theater July 20, killing 12 and injuring 58.
