From the article:
Both the student and his parents were "very cooperative" with authorities, Luque said. He said fire officials also went to the student's home and checked the garage to make sure items there were neither harmful nor explosive.
"There was nothing hazardous at the house," Luque said.
The student will not be prosecuted, but authorities were recommending that he and his parents get counseling, the spokesman said. The student violated school policies, but there was no criminal intent, Luque said.
"There will be no (criminal) charges whatsoever," Luque said.
Police and fire officials also will not seek to recover costs associated with responding to the incident, the spokesman said.
Luque said both the student and his parents were extremely upset.
"He was very shaken by the whole situation, as were his parents," Luque said.
