An investigator said Thursday that Aurora, Colorado mass shooter James Holmes’ computer showed records of a Bing search of the words “rational insanity.”
Holmes pled not guilty by reason of insanity for the shooting the killed 12 people and injured 70 who were watching the midnight showing of the Batman movie on July 20, 2012.
Aurora police detective Michael Leiker testified about the search during a pretrial hearing, but he wasn’t asked by the prosecution or defense to elaborate when the search was done and who it was done by, the AP reports.
This isn’t the first piece of online evidence the prosecution might use to argue Holmes knew the difference between right and wrong. Monday, prosecutors claimed to have found posts like “Will you visit me in prison?” on Holmes’ online dating profiles.
Holmes’ lawyers are arguing that the digital evidence may have been uncovered through an unlawful search, and therefore should be excluded.
Jury selection is scheduled to begin in February.
