The Sheriff said the “Hero” player foiled a massive school shooting planned in California town.

Officials touted the young Tennessee gamers as heroes after the boy foiled a mass shooting allegedly planned and discussed by two Tehama County teenagers on the gamer chat website.

Tehama County Sheriff Dave Dave Kain said in a press conference Tuesday that two boys, aged 14 and 15, planned to conduct a shooting at the Evergreen Institute of Excellence in Cottonwood, Northern California town, and they are expected to kill up to 100 people. Before the fatal attack, the two close friends allegedly planned to kill a set of parents.

“It’s serious,” Kane said. “This will change our entire community.”

The two friends allegedly wrote a manifesto for the fatal attack, took pictures of themselves in the 1999 Columbine mass shooting, posing as teenage killers, and talked about the planned shooting in a chat in online games.

It was during that game chat that a Tennessee boy realized the possible attack and decided to call Tehama County Sheriff’s office on the evening of May 9 for the disturbing chat.

Kane said gamers decided to call authorities about possible attacks that could save lives.

Kane said: “This young man has the courage and heroic instinct to call our agents and inform us to mitigate any possible threat to our citizens and our young people.”

Gamers provide investigators with game tags for suspects, chat content, and shared photos, one of which poses like a Columbine School shooter.

Kane said the shared image helped investigators contact school administrators, identify two students and detain them both.

“Our investigators took this technique seriously from the beginning,” Kane said.

Investigators provided a search warrant at the homes of two suspects who found they believed to be improvised explosive devices used in school attacks. Kane said the gun was also seized.

He said the two friends planned to launch an attack on May 9, but not because one of them quit. It is not clear what the motive for the school shooting was, but Kane said a teenage suspect was bullied during an interview with investigators.

Kane said the two suspects were booked in the case of alleged criminal threats, possession of destructive devices, manufacturing of destructive devices and conspiracy to commit a felony. Investigators also work with prosecutors and study the possibility of conspiracy to commit mass murder.

The two teenagers appeared in court Thursday and were ordered to be detained at the request of the Tehama County District Attorney’s Office, according to an office statement.

Kane said sheriff’s officers had spoken with school administrators to provide additional security at the school, but said the threat of quarantine was quarantined to two suspects who had been detained.

For confidence, the sheriff said his son returned to the same middle school on Monday for classes.

Kain declined to provide any details about underage gamers who reported threats, but said he and his parents were invited to visit Tehama County to gain recognition.
