CENTENNIAL, Colo. (CBS4) – CBS4 has learned from reliable law enforcement sources that James Holmes has made multiple suicide attempts in recent days, and at least one of the attempts led to a brief hospitalization.

Defense attorneys for Holmes went to court Wednesday to request a hearing for Holmes set for Thursday be postponed, but they were vague about precisely what happened.

A public defender declined in court to say what was ailing Holmes.

“It’s not as simple as a migraine,” she said.

Law enforcement contacts, speaking on the condition of anonymity, told CBS4 investigator Brian Maass that Holmes jailhouse suicide attempts were viewed as being “half-hearted,” with one of them involving him running into a wall in his jail cell, another involving him jumping off his bed.

CBS4 has learned that the hospital trip Tuesday was for diagnostic testing following one of the attempts.

Reached by phone Wednesday afternoon, Arapahoe County Sheriff Grayson Robinson declined to confirm the CBS4 report, citing an ongoing gag order in the Holmes case.

Over prosecution objections, a judge went along with the defense motion to postpone the hearing until Dec. 10.
