Washington: James Holmes, who allegedly killed 12 people during the screening of the latest Batman film ``The Dark Knight Rises,`` could face a dozen first-degree murder charges, according to court documents.
The anticipated counts were mentioned in a judge`s order directing the University of Colorado, where Holmes was a student, not to disclose information about him.
First-degree murder can be punishable by death in Colorado, The Sydney Morning Herald reports.
Colorado State Public Defender Douglas Wilson, who is representing Holmes, didn`t comment on the filing.
Holmes, 24, made an appearance on July 23 in a Centennial, Colorado, courtroom where he was advised of his rights.
He has been in custody since his arrest the night of the shootings.
According to the paper, the recent shooting incident was the deadliest in Colorado since the Columbine High School massacre in April 1999 and the worst mass shooting in the US since November 2009, when 13 people were killed at Fort Hood in Texas.
