CENTENNIAL, Colo. – The suspect in the Colorado shooting rampage tried unsuccessfully to call his university psychiatrist nine minutes before he opened fire during a Batman movie premiere, defense attorneys revealed in court Thursday.

James Holmes placed the call to an after-hours number at a hospital at the University of Colorado, Anschutz campus, where psychiatrist Lynne Fenton could be reached, defense attorney Tamara Brady said.

It wasn’t clear why he called Fenton, and she wasn’t immediately available to talk to him. Holmes, 24, is accused of opening fire during a midnight showing of “The Dark Knight Rises,” killing 12 people and injuring 58 others.
