TUSCON, Ariz (CNN/PIX11) — Five Arizona high school students, some as young as 15 years old, are accused of plotting to kill a classmate.

Now, authorities are praising a mystery student for alerting someone at the school of the alleged plot.

“Fortunately, we had one that stepped up and did the right thing and said that they knew about something that was happening,” said Tucson Police Sgt. Pete Dugan.

Police say the students, Christopher Gibson, 18, is an adult,  Anastasia Lakin and Jessica Good, both 17, and Gabriel Quiroga and Andrew Totten, both 15, were plotting to kill a fellow student at Flowing Hills High School for about a week. Several students who spoke with CNN said the target was an ex-boyfriend of someone within the group.

Tucson police say the plot was well coordinated, including several meetings before or after school. The possible murder plot got so far, one of those arrested even brought a knife to campus. “They had even decided where the murder would take place, somewhere off campus. These meetings went on for about a week,” Duggan said.

All of the teens will be charged as adults.
