James Holmes, the accused killer in the Aurora, Colorado Massacre, had been part of a University of Colorado-Denver research group carrying out innovative studies on the systems biology of olfaction. The scientists worked in the laboratory of Diego Restrepo, Ph.D. A National Institutes of Health (NIH) “Neuroscience Training Grant,” totaling $179,514, was awarded to Dr. Restrepo, team project leader, in 2012. Holmes had dropped out of the group and was in the process of withdrawing from the university.
