The University of Colorado, where Holmes was enrolled in a Ph. D. neuroscience program, has also been tight-lipped about the case. Investigators said he began stockpiling firearms and ammunition while taking classes in the spring.
In June, he made threats to a professor and on June 10 filed withdrawal papers after failing a year-end exam, prosecutors said. The next day he saw his school psychiatrist who tried to report him to a campus security committee, according to Holmes' lawyers.
