(AURORA, Colo.) — Colorado shooting suspect James Holmes was being treated by a psychiatrist, according to a legal document filed by his attorneys.
The documents reveal that Holmes was under the psychiatric care of Dr. Lynne Fenton and the documents confirm that he mailed a package to his doctors that authorities have since seized.
Holmes, 24, is accused of going on a shooting spree in an Aurora, Colo., movie theater during a midnight showing of The Dark Knight Rises on July 20. Twelve people were killed and 58 wounded.
Investigators are analyzing a notebook believed to be written by Holmes that could be a roadmap to a massacre.
Holmes’ attorneys filed the motion demanding that the court “immediately produce all discovery pertaining to the seizure of the package.”
The attorneys claim that seizing the package was a breach of confidentiality and they accuse the government of leaking the existence of the package to the media.
“The government’s disclosure of this confidential and privileged information has placed Mr. Holmes’ constitutional rights to due process and a fair trial by an impartial jury in serious jeopardy,” his attorneys wrote.
When investigators first found the Holmes package on Monday in the mailroom at the University of Colorado, where Holmes recently dropped out as a neuroscience student, they were so concerned it — like Holmes’ apartment — would be rigged with explosives that they sent in a robot to handle it.
Inside the notebook they reportedly found plans for a massacre, including drawings of a stick-figure gunman mowing down his victims.
Holmes is expected to make his second court appearance on Monday where he will be formally charged for his alleged crimes.
