Inside the mind of a mass shooter: Local psychologist has treated patients with violent thoughts

JACKSONVILLE, Fla. — The mind of a mass shooter, the FBI and mental health experts will study the two men who carried out America’s latest mass shootings trying to figure out how to prevent another one from happening.

Thirty-one people are dead after two shootings in El Paso, Texas and Dayton, Ohio over the weekend, detectives are now searching for a motive.

The shooter accused in the El Paso shooting at a Walmart left a four-page manifesto behind before the shooting.

It was posted on the online messaging board 8Chan, and the third time a suspect has believed to have posted there before an attack.

The company Cloudflare announced they will no longer provide network services to 8Chan.

President Donald Trump has called on social media companies to create tools that would detect a mass shooter before the shooting took place.


Forensic psychologist Dr. Justin D’Arienzo, said manifestos are legacy tokens, shooters hoping to leave their mark.

"They typically do want to be remembered, they do want to be recognized, they want to be viewed as a superhero in some way." D'Arienzo said. 
A killer's last word could live on the internet forever, but some people seek help for their dark thoughts.

"I've seen a handful of people throughout the years that have reported having fantasies or desires of hurting other people."
In the 15 years Dr. D'Arienzo has been a psychologist, several people have come to him in the past fantasizing about carrying out a shooting.

Some saying they think about shooting up their place of work.

D’ Arenzo encourages anyone who has thoughts of hurting someone else to seek help immediately.
