For purposes of this subsection, encased means enclosed in a case that is expressly made for the purpose of containing a firearm and that is completely zipped, snapped, buckled, tied, or otherwise fastened with no part of the firearm exposed. (2) Any firearm possessed in violation of subsection (1) of this section shall be confiscated without warrant by a peace officer or may be confiscated without warrant by school administrative or teaching personnel. Any firearm confiscated by school administrative or teaching personnel shall be delivered to a peace officer as soon as practicable. (3) Any firearm confiscated by or given to a peace officer pursuant to subsection (2) of this section shall be declared a common nuisance and shall be held by the peace officer prior to his or her delivery of the firearm to the property division of the law enforcement agency which employs the peace officer. The property division of such law enforcement agency shall hold such firearm for as long as the firearm is needed as evidence. After the firearm is no longer needed as evidence, it shall be destroyed in such manner as the court may direct.

(1) Each school district shall adopt a policy requiring the expulsion from school for a period of not less than one year of any student who is determined to have knowingly and intentionally possessed, used, or transmitted a firearm on school grounds, in a vehicle owned, leased, or contracted by a school being used for a school purpose or in a vehicle being driven for a school purpose by a school employee or his or her designee, or at a school-sponsored activity or athletic event. For purposes of this section, firearm means a firearm as defined in 18 U.S.C. 921. The policy shall authorize the superintendent or the school board or board of education to modify the expulsion requirement on an individual basis. (2) Each school district shall provide annually to the State Department of Education: (a) An assurance that the school district has in effect the policy required by subsection (1) of this section; and (b) A description of the circumstances surrounding any expulsions imposed under the policy required by subsection (1) of this section, including: (i) The name of the school concerned; (ii) The number of students expelled from the school; and (iii) The types of weapons concerned.

(3)  The expulsion of a student for (a) the knowing and intentional use of force in causing or attempting to cause personal injury to a school employee, school volunteer, or student except as provided in subdivision (3) of section 79-267 or (b) the knowing and intentional possession, use, or transmission of a dangerous weapon, other than a firearm, shall be for a period not to exceed the remainder of the school year in which it took effect if the misconduct occurs during the first semester. If the expulsion takes place during the second semester, the expulsion shall remain in effect for summer school and may remain in effect for the first semester of the following school year. Such action may be modified or terminated by the school district at any time during the expulsion period. (4)  The expulsion of a student for the knowing and intentional possession, use, or transmission of a firearm, which for purposes of this section means a firearm as defined in 18 U.S.C. 921 as of January 1, 1995, shall be for a period as provided by the school district policy adopted pursuant to section 79-263. This subsection shall not apply to (a) the issuance of firearms to or possession of firearms by members of the Reserve Officers Training Corps when training or (b) firearms which may lawfully be possessed by the person receiving instruction under the immediate supervision of an adult instructor who may lawfully possess firearms. (5)  Any expulsion that will remain in effect during the first semester of the following school year shall be automatically scheduled for review before the beginning of the school year. The review shall be conducted by the hearing examiner after the hearing examiner has given notice of the review to the student and the student’s parent or guardian. This review shall be limited to newly discovered evidence or evidence of changes in the student’s circumstances occurring since the original hearing. This review may lead to a recommendation by the hearing examiner that the student be readmitted for the upcoming school year. If the school board or board of education or a committee of such board took the final action to expel the student, the student may be readmitted only by action of the board. Otherwise the student may be readmitted by action of the superintendent.
