In this blog series, we explore historical events to teach us what pre-incident indicators were present to decrease the chance of bad things from happening in the future.

The Background:

In 2011, Jared Lee Loughner killed six and wounded thirteen people at a public and scheduled event for U.S. Representative Gabrielle Giffords. Loughner was a high school drop-out with a history of mental illness, drug and alcohol abuse, a fixation on firearms, inability to keep a job, and displayed bizarre and disruptive behaviors in the classroom. Loughner was very active in the online world, to include postings of disturbing and threatening statements on MySpace and YouTube, while referencing suicidal ideations and threats against police officers. 

Loughner’s fixation with Giffords began in 2007 after the two met at a community event. Allegedly, Loughner did not like the way Giffords responded to one of his questions, which culminated in the attack approximately four years later (reported by CNN). It doesn’t appear that Loughner attempted direct contact with Giffords between that period of time, but it’s unclear if he stalked her online.   

Summary of Incident Events:

  • On January 8, 2011 at 10:10 am in Tucson, AZ, 22-year-old Jared Loughner, a Caucasian white male, killed six and wounded thirteen people with a Glock 19 9mm handgun. Congresswoman Giffords was the intended target. She was shot and wounded. (Reported by the Department of Homeland Security)
  • Loughner had four magazines (two were extended 30 round magazines) and a knife on his person. The attack took place at a public venue where Giffords had set up a constituent meeting in front of a Safeway supermarket. Loughner approached the tables set up for the meeting and began firing at 10:10am. All of the victims were shot during this time. The incident ended with the attacker being subdued by people who were attending the meeting at 10:15am. (Reported by Advanced Law Enforcement Rapid Response Training)
  • Communications discovered after the attack indicated that Loughner may also have been seeking fame as an assassin.
