James Holmes, the alleged shooter in the Aurora movie theater massacre, was taken to a hospital after running headfirst into a jail cell wall.
Law enforcement authorities described his self-inflicted injuries as "half-hearted" attempts to commit suicide, CBS4 Denver reported.
Holmes was hospitalized on Tuesday although he was not seriously hurt.
Though he was released yesterday, the judge accepted a request from his attorneys to postpone a hearing today due to Holmes' stay in an area hospital.
Holmes is accused of shooting 70 people, killing 12 of them, at a midnight screening of "The Dark Knight Rises" on July 20.
The 24-year-old's lawyers were deliberately vague about their client's medical condition.
"It's not as simple as a migraine," public defender Tamara Brady said, "and it's not something that will resolve itself by [this] morning."
Sources told KOAA that Holmes stood on his bed and fell backwards, apparently trying to crack his head. He followed that by running headfirst into his jail cell wall and on a third try to hurt himself, hit his head against the wall.
The prosecution objected to the request to reschedule the hearing, saying that the defense needed to give an explanation of what happened to Holmes, the Denver Post reported.
