The US man accused of being the Golden State Killer did not enter a plea during his first court appearance.
Joseph James DeAngelo was formally charged on Friday in Sacramento County Superior Court on two counts of murder.
He was handcuffed in a wheelchair and five police officers surrounded him as he listened to the judge with his eyes barely open.
A court official read the details of the charges that DeAngelo is facing and a judge asked if he had a lawyer.
In a frail voice, DeAngelo responded: "I have a lawyer."
An attorney from the public defender's office was with him in court.
DeAngelo has been denied bail.
