What evidence found in James Holmes’ apartment says about him

While accused killer James Holmes’ attorneys have said he's mentally ill, the items investigators recovered from his apartment send a strong signal that he was not mentally debilitated, a former FBI profiler tells Yahoo News.

“Let’s put the labels aside and look at the behavior,” says Mary Ellen O'Toole, who worked for 15 years in the bureau's Behavioral Analysis Unit where she studied psychopaths and helped capture killers.
Holmes, a former neuroscience student at the University of Colorado at Denver, is charged with killing 12 people and wounding 58 others when he opened fire inside a packed Aurora, Colo., movie theater nine months ago. Previously sealed evidence logs and related search warrants from the investigation were made public on Thursday.
At Yahoo News’ request, O'Toole—who retired in 2009 and has no direct connection to the case—reviewed 17 pages of items taken from Holmes’ apartment.
“There were items he needed to carry out his game plan,” O’Toole said of the evidence. “They show the thinking and the logic and the strategy.”

Bomb materials, supply lists, gun-cleaning tools all point to Holmes being in touch with reality, she said.
“The amount of planning and thoughtfulness, and money and time that had to go into this is really reinforced here,” she added. “You can’t put together a list like this overnight.”
From his bathroom, police recovered Sertraline, an antidepressant, and Clonazepam, which is often used to treat anxiety, bipolar and panic disorders. Over-the-counter allergy, cold and pain medications were found as well.
Investigators also removed 50 cans and bottles of beer, whiskey and rum. But finding the pills and booze doesn’t prove that Holmes was consuming them or consuming them as prescribed, O’Toole said.
“If you’re a bombmaker, you don’t want to think fuzzy,” she said. “He couldn’t afford to make a mistake.”

In addition to the theater shooting rampage, investigators have testified, Holmes tried to blow up his third-floor apartment to distract emergency workers from the theater.
Among other items police seized:
  • Batman mask
  • Numerous textbooks related to biology, neuroscience and psychology
  • Posters for movies including "Pulp Fiction" and video games including Skyrim
  • Hard-core action books
  • Several computers and electronic storage devices
  • Role-playing action video games including Oblivion and StarCraft
Holmes’ defense team recently said he would plead guilty in exchange for a sentence of life in prison. Prosecutors rejected the offer and will seek the death penalty. The trial is tentatively scheduled for February 2014.
O’Toole said she hopes the jury doesn’t “jump over the wealth of behavior within the crime scene” and merely label Holmes as being crazy.
“Most people who do suffer from a debilitating mental illness are just not violent … not in this predatory, cold-blooded way,” she said.
