As attorneys for the suspect in a Colorado movie theater rampage fight to find the source of media leaks about his case, more details are emerging about the psychiatrist who documents show treated him.

Attorneys for 24-year-old James Holmes disclosed he was a "psychiatric patient" of Dr. Lynne Fenton in a court motion Friday, as they sought to discover the source of leaks to media outlets that he sent the psychiatrist a package containing a notebook with descriptions of an attack.

The revelation is the first indication that Holmes may have sought help before the rampage that killed 12 people and wounded 58.

Records show Fenton has faced some trouble in her career. She was disciplined by the Colorado Medical Board in 2004 for prescribing herself Xanax while her mother was dying, state records show. She also was disciplined for prescribing the sleep aid Ambien and the allergy medicine Claritin for her husband, and painkillers for an employee who suffered from chronic headaches.

The University of Colorado's website identified Fenton as the medical director of the school's Student Mental Health Services. An online resume stated that she sees 10 to 15 graduate students a week for medication and psychotherapy, as well as 5 to 10 patients in her general practice as a psychiatrist. Schizophrenia was listed as one of her research interests.

Fenton worked for the U.S. Air Force in Texas as an acupuncturist before joining the University of Colorado in 2005.

A 1998 Denver Post article quotes a Colorado acupuncturist named Lynne Fenton discussing how acupuncture could be used to enhance women's busts.

In the motion, defense attorneys seek to discover the source of leaks to the media about the package Holmes sent, which was first reported Wednesday by FoxNews.com, citing unnamed sources. Other media outlets scrambled to report the story and may have also talked to sources in position to know about the notebook.

The package was seized by authorities Monday after it was discovered in a mailroom at the school's Aurora campus.

A law enforcement source told FoxNews.com that the notebook contained sketches and other details that appear to have foreshadowed the horrific attack, in which Holmes allegedly burst into a theater and shot 70 people, killing 12.

"Inside the package was a notebook full of details about how he was going to kill people," the source told FoxNews.com. "There were drawings of what he was going to do in it -- drawings and illustrations of the massacre."

Among the images shown in the spiral-bound notebook’s pages were gun-wielding stick figures blowing away other stick figures.

The notebook is now in possession of the FBI, sources told FoxNews.com.

The source told FoxNews.com the package was mailed well before the attack took place, but had not been delivered to its intended recipient. The school issued a statement Wednesday evening confirming that a suspicious package was found, but said it was delivered Monday and found on the same day.

The motion said the leaks jeopardized Holmes' right to a fair trial and violated a judge's gag order.

Holmes' lawyers added that the package contained communications between Holmes and Fenton that should be shielded from public view.

The motion did not reveal when Holmes began seeing Fenton or whether he was being treated for a mental illness. Legal analysts expect Holmes' attorneys to use an insanity defense at trial. Holmes is scheduled to be arraigned Monday. A hearing on the new defense motion also is scheduled that day.

Calls to Holmes' lawyer and the state public defender's office were not immediately returned, nor was a message left with Fenton's office. A spokeswoman for the Arapahoe County prosecutor's office declined comment.
