James Holmes (Centre) offered to plead guilty, but prosecutors rejected

A psychiatrist who's husband accused of killing 12 massacre in Colorado in July before police had treated cinema warned he was a danger to the public.

New released documents that show Dr. Lynne Fenton told police of threatening text messages that James Holmes sent after he stopped attending counselling Court.

Mr Holmes, 25, has been charged with multiple counts of murder at the attack during a Prime Minister of a Batman movie.

Prosecutors have rejected a guilty plea and seek the death penalty.

The process had planned for August, but a judge has pushed it back until February 2014.

Burned accounts

In an affidavit taken after the shooting and unsealed on Thursday, University of Colorado Denver police officer Lynn Whitten told investigators that Dr Fenton had contacted her in June.

Dr Fenton followed a legal claim to the report of a specific threat to the authorities, according to the document.

MS Whitten said the psychiatrist was making the report "as a result of murderous statements [Mr Holmes] had made" and that Dr. Fenton said he sent threatening text messages to her after he stopped attending counseling sessions.

Mr Holmes was a graduate student in Neuroscience at the University of Colorado in Denver but was retires from his studies on in the absence of an important exam.

Earlier reports said that Dr. Fenton had told campus authorities about Mr Holmes, but not that they had made a report of specific threats.

A warrant also unsealed on Thursday described a package sent to Dr Fenton before the massacre, apparently by Mr Holmes. It included a Brown laptop labeled "of life" that officials believe like a diary, as well as partially burned $ 20 bills.

The documents were previously sealed, but a new judge overseeing the case ordered them released in response to requests from the media organizations.

Separately, Judge William Sylvester has removed themselves from the case after prosecutors announced they would seek the death penalty.

Judge Sylvester said en route that the case would take so much time, that he is not of his administrative duties as Chief Judge of a busy four-county district could carry.

The district judge Carlos Samour took the case on Monday.
