A. The governing board shall:

• 30. Report to local law enforcement agencies any suspected crime against a person or property that is a serious offense as defined in section 13-706 or that involves a deadly weapon or dangerous instrument or serious physical injury and any conduct that poses a threat of death or serious physical injury to employees, students or anyone on the property of the school. This paragraph does not limit or preclude the reporting by a school district or an employee of a school district of suspected crimes other than those required to be reported by this paragraph. For the purposes of this paragraph, “dangerous instrument”, “deadly weapon” and “serious physical injury” have the same meanings prescribed in section 13-105.

G. A school district or charter school shall expel from school for a period of not less than one year a pupil who is determined to have brought a firearm to a school within the jurisdiction of the school district or the charter school, except that the school district or charter school may modify this expulsion requirement for a pupil on a case by case basis. This subsection shall be construed consistently with the requirements of the individuals with disabilities education act (20 United States Code sections 1400 through 1420). For the purposes of this subsection:

• 1. “Expel” may include removing a pupil from a regular school setting and providing educational services in an alternative setting.
• 2. “Firearm” means a firearm as defined in 18 United States Code section 921.
