AURORA, Colo. — Before the movie theater massacre last week, the suspected gunman had been seeing a psychiatrist at the University of Colorado and mailed her a package containing a notebook, according to a motion filed by James E. Holmes' public defenders.

In the filing released Friday, Holmes' lawyers say that, after law enforcement executed a search warrant at the university this week and seized the package addressed to Dr. Lynne Fenton, someone leaked information about it to the media — including allegations that Holmes had alerted law enforcement to it. The release of such information would violate a gag order issued by the judge in the case.

"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 at serious jeopardy," Holmes' lawyers wrote.

The filing did not say why Holmes, 24, was seeing Fenton, who did not return calls to her office on Friday. At the brick home in Denver where she was believed to live, the windows were closed and no one answered the door.

Fenton, 51, graduated from the University of California, Davis, in 1982 and Chicago Medical School in 1986. She completed a residency in physical medicine and rehabilitation at Northwestern University Medical Center in 1990. After working as chief of physical medicine for the U.S. Air Force in San Antonio, as a physician in Aurora, and later as an acupuncturist, she completed a second residency in psychiatry at the University of Colorado in 2008, according to a resume on the school's website.

She has been an assistant professor and, for the past three years, medical director of the student mental health service at the university's Anschutz Medical Campus in Aurora, where Holmes had been a neuroscience doctoral student until he began the process of withdrawing in June.

"Most students receive combined treatment of psychotherapy and medications from a single provider" at the center, according to a center brochure, and center staff "consults with (medical school) staff regarding students of concern."

Fenton is also listed as faculty at the medical school's Schizophrenia Research Center and has received grants to study the effect of various drugs on schizophrenics.

On May 30, Fenton helped make a presentation at the psychiatry department called "World of Warcraft: The Use of Archetypes in Psychotherapy." World of Warcraft, a popular multiplayer role-playing video game, was among those Holmes played, according to a former roommate at the University of California, Riverside.

In the motion released Friday, Holmes' lawyers demanded access to the package seized from the university mailroom, the names of the investigators involved in testing it for explosives, the chain of custody, specifics related to the questioning of Holmes about the package and potential leaks to the media.

Multiple news outlets had cited unidentified sources in reporting that Holmes mailed a notebook to the medical campus before the July 20 attack, when a gunman sprayed a crowded theater that was showing the latest Batman movie. The notebook was said to contain drawings of stick figures being shot and a written description of a coming attack, according to Fox News, which first reported its existence. The FBI and other law enforcement agencies refused to comment on the reports.

University officials confirmed they had received a suspicious package on Monday, three days after the assault that left 12 dead and 58 injured — about a dozen of whom remained hospitalized Friday, five in critical condition.

The package was "immediately investigated and turned over to authorities within hours of delivery," a university statement said — contradicting media reports that it had arrived before the attack but sat around unopened until Monday.

Arapahoe County District Attorney Carol Chambers filed a motion Friday asking the judge to reject the public defenders' request, denying authorities had leaked any information and noting as evidence the inaccuracy of media reports.

Contrary to those reports, she said, the police department took custody of the package, not the FBI; one search warrant was needed, not two; and the package remained "secured and not examined."
