(1) The unlawful concealed carrying upon the person or within the vehicle of the carrier of any machine gun, pistol, revolver or other firearm or weapon described in this chapter capable of being concealed upon the person, or any firearm used during the commission of any felony or misdemeanor is a nuisance. Any such weapons taken from the person or vehicle of any person unlawfully carrying the same are nuisances, and shall be surrendered to the police chief.

(2) Upon the certificate of a judge of a court of record or of the district attorney that their preservation is necessary to the proper ends of justice, the police chief shall preserve any weapons seized or surrendered hereunder until the necessity therefore ceases to exist. Thereafter, unless the weapon has been stolen and its lawful owner has provided satisfactory identification of the weapon and proof of ownership so as to secure its return, the police chief shall dispose of the weapon in accordance with section 2.835(3) of this code.
