The James Holmes trial continues in Colorado as Aurora Police Sgt. Matthew Fyles read excerpts from the "Batman" shooter's notebook Tuesday.
According to CNN, the notebook titled "Of Life" has become a key piece of evidence in the trial as prosecutors aim to convince the jury that 27-year-old Holmes planned out his July 20, 2012, massacre during a movie screening of "The Dark Knight Rises."
Holmes reportedly sent the 29-page book — which details his thoughts on types of attacks and preferred venues in which to kill a large number of people — to University of Colorado psychiatrist Lynne Fenton before the shooting.
“The obsession to kill since I was a kid, with age became more and more realistic,” Holmes wrote in the notebook, according to CNN.
Accused of killing 12 people and injuring 70, Holmes has pleaded not guilty by reason of insanity and could face the death penalty if convicted on the 165 counts against him.
The book also explains how Holmes believed people would attribute his failures with jobs and women to the incident. Instead, Holmes wrote, “There is no message.”
“Both (failures) were expediting catalysts, not the reason. The causation being my state of mind for the past 15 years,” Holmes wrote.
He reportedly decided on targeting a large gathering despite noting a “99-percent” chance he would be caught, according to CNN.
Diagrams of the theater and plans to perform the shooting are also included in the book.
But defense attorney Daniel King, who is trying to prove Holmes' insanity, pointed at other posts to illustrate his client's confusing mindset, including several pages where the word "Why" is
repeated over and over, according to The Associated Press.
