A police officer testified in court Colorado cinema gunman James Holmes wrote in a notebook he sent to his psychiatrist prior to opening fire in a suburban theater that he had harbored an “obsession to kill” since childhood. Prosecutors have said they will seek the death penalty for Holmes if he is convicted of killing 12 moviegoers and wounding 70 others in the July 2012 rampage. Aurora Police Sergeant Matthew Fyles read aloud excerpts from the 29-page notebook, in which Holmes allegedly wrote: “The obsession to kill since I was a kid, with age became more realistic.”
