The universities attended by James Holmes, who faces charges in the killings in Aurora, Colo., offered some information about Holmes on Friday, but little that would explain what happened.

• Timothy P. White, chancellor of the University of California at Riverside, held a news conference Friday in which he said that Holmes enrolled as an undergraduate in 2006 and graduated in 2010 as an honors student in neuroscience, earning merit scholarships along the way. White said that there was no evidence of any contact between Holmes and law enforcement while he was enrolled at Riverside.
• The University of Colorado at Denver issued a brief statement that Holmes was in the process of withdrawing from a graduate program in neurosciences.
• On Sunday, the University of Colorado said it was investigating whether Holmes used his graduate student position to have materials shipped to the university for his use setting up booby traps in his apartment, the Associated Press reported.
