A Colorado judge has scheduled an Aug. 5 trial for the man charged with a deadly movie theater shooting.

The judge entered a not guilty plea on behalf of James Holmes Tuesday after the former graduate student's defense team said he was not ready to enter one.

Prosecutors plan to announce whether they'll seek the death penalty at an April 1 hearing.

Holmes is charged with multiple counts of murder and attempted murder in the July 20 attack at an Aurora movie theater that killed 12 people and injured 70.

He sat silently through Tuesday's proceedings and wore a red jail jumpsuit. He sported a thick, bushy beard and unkempt dark brown hair.

His parents, James and Arlene Holmes, sat silently at the front of the courtroom.

One of the upcoming hearings in the Colorado theater shooting case will focus on who leaked information about a notebook that James Holmes sent to a psychiatrist.

The judge in the case says he'll hold a hearing the week of April 1 to find out who violated a gag order in the case.

One of Holmes' lawyers said Tuesday that a judge in New York has signed a subpoena for Fox News reporter Jana Winter to testify about her story, which cited unidentified law enforcement officials.

Holmes' attorneys are trying to get Winter to disclose her sources. Her lawyer has said that shield laws in New York and Colorado protect Winter from demands to reveal her sources.
