A judge denied bond for two teens charged with attempted murder after a sheriff said on Thursday that they were planning a ‘Columbine-style’ attack on their high school in Georgia.

According to WGCL, police said a tip from a parent led them to the teens and their homes, where officers found flammable devices, a container filled with an undetermined powder and a journal detailing their plans.

Investigators said the teens likely had access to their parent’s weapons, but said neither teen had weapons in their possession at the time of their arrests. Sheriff Frank Reynolds told WGCL Thursday that the device was similar to a Molotov cocktail.

He said the tip from a parent likely saved lives, calling the person who alerted authorities to the plot a “hero,” according to WSB.

“To me that person is a hero, that’s what we want to do. We want to have the support of our community and the number one thing we want to have with our community is trust,” Reynolds said.

Alfred Dupree, 17, and Victoria McCurley, 17, have reportedly been charged as adults.

Both teens reportedly attended Etowah High School in Cherokee County, which is located approximately 30 miles northwest of Atlanta.

Classmates described the teens to WGCL as ‘loners’ and said they wondered whether Dupree and McCurley had other people helping them with the plan.

At this time, Reynolds said authorities believe the teens charged were the only ones involved in the plan.

Both suspects face three counts of criminal attempt to commit murder, four counts of terroristic threats and acts, criminal attempt to commit arson and possession and/or transportation of destructive device/explosive with intent to kill, injure or destroy any public building.

A judge has sealed the teen’s arrest warrants, WGCL reported, so additional information available regarding the case remains limited.
