HAWKINS COUNTY, TN (WBIR) - Hawkins County Sheriff Ronnie Lawson said two teenagers created an extensive plan to kill as many students and staff as possible at Volunteer High School.

"I want you to know that this wasn't just a threat - it was a planned attack," said Lawson during a press conference Friday morning.

During a search of one of the suspect's home, investigators said they uncovered several guns, gunpowder, firecrackers, floor plans of Volunteer High School, and journals, detailing the attack.

The plans in the journals specified where to block the school's exits, how to kill the school security officers first, and research on how to kill the most people, according to Lawson.

"[The journals] studies the maximum amount of students in the lunchroom and hallways, where to block the exits, and to eliminate the SRO officer first," said Lawson.

The sheriff said the suspects even tried to recruit other students; officials have interviewed all of them.

Lawson said the mass school shooting at Columbine High School in 1999 inspired planned attack on Volunteer High School.
