James Holmes, who allegedly killed 12 people during the screening of 'The Dark Knight Rises' at a movie hall in the US, is mentally ill, his lawyers have claimed.
Attorneys for James Holmes, while speaking at a court hearing in Denver, also said that their client tried to get help before the massacre.
Defense attorney Daniel King made the revelation about Holmes as he argued defense attorneys need more information from prosecutors and investigators to assess their client.
"We cannot begin to assess the nature and the depth of Mr. Holmes' mental illness until we receive full disclosure," the Telegraph quoted him, as saying.
According to the paper, King also said Holmes sought out university psychiatrist, Lynne Fenton, for help.
Holmes, 24, has been accused killing dozens of people and injuring nearly 58 after he carried out a shooting rampage on July 20 during the screening of the latest Batman film at a movie hall in Colorado.
