Editor's note: Theย man accused of opening fire in a crowded movie theater in Aurora, Colorado, is set to make his first court appearance Monday, giving the public its first look at the suspect since his arrest in an attack that authorities say was planned months in advance. We're live blogging the court appearance, which begins at 11:30 a.m. ET.
[Posted at 12:11 p.m. ET] The district attorney's press conference has concluded.

[Posted at 12:09 p.m. ET] Asked by a reporter if any medication or sedatives had been provided by the jail to Holmes, Chambers said she had no information about it.
[Posted at 12:07 p.m. ET] "It's still a very active and ongoing investigation," Carol Chambers, Arapahoe County district attorney, said Monday.

[Posted at 11:27 a.m. ET] ย The public information officer for Colorado courts tweets that the district attorney in the James Holmes case will hold a press conference after the hearing.
[Posted at 11:09 a.m. ET] ย James E. Holmes, 24, is likely to face charges of first-degree murder - an offense that carries a possible death penalty, if he is convicted - in the shooting deaths, given allegations over the weekend by police that there is evidence to suggest "calculation and deliberation" in the rampage.
Holmes is being held in connection with the early Friday morning shootings that left 12 dead and 58 wounded, and the subsequent discovery of his booby-trapped apartment, which authorities believe he rigged before leaving for the Century Aurora 16 multiplex.
Authorities have been tight-lipped about a possible motive in the case, and police spokesman Frank Fania told CNN late Sunday that Holmes has been uncooperative with investigators and requested an attorney.
Arapahoe County public defender James O'Connor has been assigned to the case. The Colorado Judicial Department declined to say whether Holmes requested a public defender. A telephone call by CNN to O'Connor's office was not immediately returned.
Holmes' court appearance will come a few hours before his family is expected to break their silence with a statement.
The family, which lives in San Diego, has not spoken publicly since the allegations against Holmes. They issued a short statement Friday saying they did not wish to be disturbed "at the time of this tragic event."
