BARTLESVILLE, Okla. - Bartlesville police say a .22-caliber rifle was found in the home of a student suspected of plotting to shoot and bomb Bartlesville High School.
The Associated Press is reporting notes about a possible attack were also found at the home of Sammie Chavez.
A review of information obtained from the school computer used by Chavez showed searches from Nov. 30 for a .22 caliber rifle built on a machine gun platform, police say.
Police also say students witnessed Chavez not only “researching the Columbine High School massacre and remorseful letters on the 'in Memory' page," they also saw him looking at a website on how to build pipe bombs.
Early Friday morning police arrested Chavez, 18, after a tip from another student.
Investigators say Chavez wanted to lure kids to the high school auditorium, chain the doors and start shooting.
They also say he planned to leave bombs at the doors to kill officers as they approached. No bomb-making materials were found at the home, according to the AP.
Chavez is jailed on $1 million bond and is due in court Jan. 11.
Counselors were made available Monday for students returning to school for the first time since the alleged threats were made public.
In a message to parents, Superintendent Gary Quinn said there will be more police officers at schools in the district over the next several weeks.
Quinn said administrators will also talk with students about what to do if they hear about a threat to the school or other students.
During a press conference Monday, Tulsa Police Chief Chuck Jordan joined other officials to address changes to Tulsa Public Schools' security procedures. Jordan weighed in on the success of students, teachers and officers in Bartlesville in stopping a potential school shooting.
“[Communication] is one of the key factors in preventing these things is, gathering information before this happens, recognizing people who are having emotional issues who are talking about doing things like that," said Jordan. "We [have to] encourage the students and the families and everyone in our community when they hear or see anything like this."
Chris Tanea, community relations coordinator for the Bartlesville Public School District, says Monday's increased security presence is an opportunity for the district to show that while Friday's attack was thwarted, it is not backing off of tight security.
"Obviously it's a time of heightened awareness, and we felt it's really important to increase our security measures, do even more than we've been doing," Tanea said. "Our students were never in danger, but we feel like we can-- if we can add that extra level of security, we feel the need to do that."
Linda Derkez says she found the increased security encouraging Monday morning. She and her daughter Madeline, a pre-kindergarten student at Richard Kane Elementary, walked to school Monday morning and experienced the increased police presence firsthand.
"We walked to school hand-in-hand and thinking about the events on Friday and whether it's safe or not and when we got near the school there were two policeman at the door and it was very good to see," Derkez said. "And I said to them, 'I would like to see you here every day.'"
Derkez, who lives closer to the high school, says the increased security is a necessity.
"I live right next -- near the school -- that school, so I mean it's just a shock and at the same time not a shock anymore because it keeps happening and you worry that it's going to continue happening, so they need to make these steps."
Chavez's arrest came on the same day as one the country's deadliest school shootings.
Around 9:30 a.m., a gunman entered Sandy Hook Elementary School in Newtown, Conn. and opened fire on adults and children alike.
Within 10 minutes, 20-year-old Adam Lanza had shot and killed 20 children and six adults and then turned the gun on himself.
Investigators later learned Lanza started the massacre with his own mother at the home they shared.
